EnerVenue raises $100M to accelerate clean energy using nickel-hydrogen batteries
In order to support a buildout of renewable energy, which tends to over-generate electricity at certain times of day and under-generate at others, the grid is going to need a lot of batteries. While lithium-ion works fine for consumer electronics and even electric vehicles, battery startup EnerVenue says it developed a breakthrough technology to revolutionize stationary energy storage.
The technology itself — nickel-hydrogen batteries — isn’t actually new. In fact, it’s been used for decades in aerospace applications, to power everything from satellites to the International Space Station and the Hubble Telescope. Nickel-hydrogen had been too expensive to scale for terrestrial applications, until Stanford University professor (and now EnerVenue chairman) Yi Cui determined a way to adapt the materials and bring the costs way, way down.
Nickel-hydrogen has a number of key benefits over lithium-ion, according to EnerVenue: it can withstand super-high and super-low temperatures (so no need for air conditioners or thermal management systems); it requires very little to no maintenance; and it has a far longer lifespan.
The technology has caught the eye of two giants in the oil and gas industry, energy infrastructure company Schlumberger and Saudi Aramco’s VC arm, which together with Stanford University have raised $100 million in Series A funding. The investment comes around a year after EnerVenue raised a $12 million seed. The company is planning on using the funds to scale its nickel-hydrogen battery production, including a Gigafactory in the U.S., and has entered a manufacturing and distribution agreement with Schlumberger for international markets.
“I spent almost three and a half years prior to EnerVenue looking for a battery storage technology that I thought could compete with lithium-ion,” CEO Jorg Heinemann told TechCrunch in a recent interview. “I had essentially given up.” Then he met with Cui, who had managed through his research to bring the cost down from around $20,000 per kilowatt hour to $100 per kilowatt hour within line of sight — a jaw-dropping decrease that puts it on-par with existing energy storage technology today.

Think of a nickel-hydrogen battery as a kind of battery-fuel cell hybrid. It charges by building up hydrogen inside a pressure vessel, and when it discharges, that hydrogen gets reabsorbed in water, Heinemann explained. One of the key differences between the batteries in space and the one’s EnerVenue is developing on Earth is the materials. The nickel-hydrogen batteries in orbit use a platinum electrode, which Heinemann said accounts for as much as 70% of the cost of the battery. The legacy technology also uses a ceramic separator, another high cost. EnerVenue’s key innovation is finding new, low-cost and Earth-abundant materials (though the exact materials they aren’t sharing).
Heinemann also hinted that an advanced team within the company is working on a separate technology breakthrough that could bring the cost down even further, to the range of around $30 per kilowatt hour or less.
Those aren’t the only benefits. EnerVenue’s batteries can charge and discharge at different speeds depending on a customer’s needs. It can go from a 10-minute charge or discharge to as slow as a 10-20 hour charge-discharge cycle, though the company is optimizing for a roughly two-hour charge and four- to eight-hour discharge. EnerVenue’s batteries are also designed for 30,000 cycles without experiencing a decline in performance.
“As renewables get cheaper and cheaper, there’s lots of time of the day where you’ve got, say, a one- to four-hour window of close to free power that can be used to charge something, and then it has to be dispatched fast or slow depending on when the grid needs it,” he said. “And our battery does that really well.”
It’s notable that this round was funded by two companies that loom large in the oil and gas industry. “I think nearly 100% of the oil and gas industry is now pivoting to renewables in a huge way,” Heinemann added. “They all see the future as, the energy mix is shifting. We’re going to be 75% renewable by mid-century, most think it’s going to happen quicker, and those are based on studies that the oil and gas industry did. They see that and they know they need a new play.”

Don’t expect nickel-hydrogen to start appearing in your iPhone anytime soon. The technology is big and heavy — even scaled down as much as possible, a nickel-hydrogen battery is still around the size of a two-liter water flask, so lithium-ion will definitely still play a major role in the future.
Stationary energy storage may have a different future. EnerVenue is currently in “late-stage” discussions on the site and partner for a United States factory to produce up to one gigawatt-hour of batteries annually, with the goal of eventually scaling even beyond that. Heinemann estimates that the tooling cap-ex per megawatt hour should be just 20% that of lithium ion. Under the partnership with Schlumberger, the infrastructure company will also be separately manufacturing batteries and selling them in Europe and the Middle East.
“It’s a technology that works today,” Heinemann said. “We’re not waiting on a technology breakthrough, there’s no science project in our future that we have to go achieve in order to prove out something. We know it works.”

Brazilian proptech startup QuintoAndar lands $300M at a $4B valuation
Fintech and proptech are two sectors that are seeing exploding growth in Latin America, as financial services and real estate are two categories in particular dire need of innovation in a region.
Brazil’s QuintoAndar, which has developed a real estate marketplace focused on rentals and sales, has seen impressive growth in recent years. Today, the São Paulo-based proptech has announced it has closed on $300 million in a Series E round of funding that values it at an impressive $4 billion.
The round is notable for a few reasons. For one, the valuation — high by any standards but especially for a LatAm company — represents an increase of four times from when QuintoAndar raised a $250 million Series D in September 2019.
It’s also noteworthy who is backing the company. Silicon Valley-based Ribbit Capital led its Series E financing, which also included participation from SoftBank’s LatAm-focused Innovation Fund, LTS, Maverik, Alta Park, an undisclosed U.S.-based asset manager fund with over $2 trillion in AUM, Kaszek Ventures, Dragoneer and Accel partner Kevin Efrusy.
Having backed the likes of Coinbase, Robinhood and CreditKarma, Ribbit Capital has historically focused on early-stage investments in the fintech space. Its bet on QuintoAndar represents clear faith in what the company is building, as well as its confidence in the startup’s plans to branch out from its current model into a one-stop real estate shop that also offers mortgage, title, insurance and escrow services.
The latest round brings QuintoAndar’s total raised since its 2013 inception to $635 million.
Ribbit Capital Partner Nick Huber said QuintoAndar has over the years built “a unique and trusted brand in Brazil” for those looking for a place to call home.
“Whether you are looking to buy or to rent, QuintoAndar can support customers through the entire transaction process: from browsing verified inventory to signing the final contracts,” Huber told TechCrunch. “The ability to serve customers’ needs through each phase of life and to do so from start to finish is a unique capability, both in Brazil and around the world.”
QuintoAndar describes itself as an “end-to-end solution for long-term rentals” that, among other things, connects potential tenants to landlords and vice versa. Last year, it expanded also into connecting a home buyers to sellers.

TechCrunch spoke with co-founder and CEO Gabriel Braga and he shared details around the growth that has attracted such a bevy of high-profile investors.
Like most other businesses around the world, QuintoAndar braced itself for the worst when the COVID-19 pandemic hit last year — especially considering one core piece of its business is to guarantee rents to the landlords on its platform.
“In the beginning, we were afraid of the implications of the crisis but we were able to honor our commitments,” Braga said. “In retrospect, the pandemic was a big test for our business model and it has validated the strength and defensibility of our business on the credit side and reinforced our value proposition to tenants and landlords. So after the initial scary moments, we actually felt even more confident in the business that we are building.”
QuintoAndar describes itself as “a distant market leader” with more than 100,000 rentals under management and about 10,000 new rentals per month. Its rental platform is live in 40 cities across Brazil, while its home-buying marketplace is live in four. Part of its plans with the new capital is to expand into new markets within Brazil, as well as in Latin America as a whole.
The startup claims that, in less than a year, QuintoAndar managed to aggregate the largest inventory among digital transactional platforms. It now offers more than 60,000 properties for sale across Sao Paulo, Rio de Janeiro, Belho Horizonte and Porto Alegre. To give greater context around the company’s growth of that side of its platform: In its first year of operation, QuintoAndar closed more than 1,000 transactions. It has now surpassed the mark of 8,000 transactions in annualized terms, growing between 50% and 100% quarter over quarter.
As for the rentals side of its business, Braga said QuintoAndar has more than 100,000 rentals under management and is closing about 10,000 new rentals per month. The company is not profitable as it’s focused on growth, although it’s unit economics are particularly favorable in certain markets such as Sao Paulo, which is financing some of its growth in other cities, according to Braga.
Now, the 2,000-person company is looking to begin its global expansion with plans to enter the Mexican market later this year. With that, Braga said QuintoAndar is looking to hire “top-tier” talent from all over.
“We want to invest a lot in our product and tech core,” he said. “So we’re trying to bring in more senior people from abroad, on a global basis.”
Some history
CEO Braga and CTO André Penha came up with the idea for QuintoAndar after receiving their MBAs at Stanford University. As many startups do, the company was founded out of Braga’s personal “nightmare” of an experience — in this case, of trying to rent an apartment in Sao Paulo.
The search process, he recalls, was difficult as there was not enough information available online and renters were forced to provide a guarantor, or co-signer, from the same city or pay rent insurance, which Braga described as “very expensive.”
“Overall, I felt it was a very inefficient and fragmented process with no transparency or tech,” Braga told me at the time of the company’s last raise. “There was all this friction and high cost involved, just real tangible problems to solve.”
The concept for QuintoAndar (which can be translated literally to “Fifth Floor” in Portuguese) was born.
“Little by little, we created a platform that consolidated supply and inventory in a uniform way,” Braga said.
The company took the search phase online for the first time, according to Braga. It also eliminated the need for tenants to provide a guarantor, thereby saving them money. On the other side, QuintoAndar also works to help protect the landlord with the guarantee that they will get their rent “on time every month,” Braga said.
It’s been interesting watching the company evolve and grow over time, just as it’s been fascinating seeing the region’s startup scene mature and shine in recent years.

Geothermal technology has enormous potential to power the planet and Fervo wants to tap it
Tapping the geothermal energy stored beneath the Earth’s surface as a way to generate renewable power is one of the new visions for the future that’s captured the attention of environmentalists and oil and gas engineers alike.
That’s because it’s not only a way to generate power that doesn’t rely on greenhouse gas emitting hydrocarbons, but because it uses the same skillsets and expertise that the oil and gas industry has been honing and refining for years.
At least that’s what drew the former completion engineer (it’s not what it sounds like) Tim Latimer to the industry and to launch Fervo Energy, the Houston-based geothermal tech developer that’s picked up funding from none other than Bill Gates’ Breakthrough Energy Ventures (that fund… is so busy) and former eBay executive, Jeff Skoll’s Capricorn Investment Group.
With the new $28 million cash in hand, Fervo’s planning on ramping up its projects, which Latimer said would “bring on hundreds of megawatts of power in the next few years.”
Latimer got his first exposure to the environmental impact of power generation as a kid growing up in a small town outside of Waco, Texas near the Sandy Creek coal power plant, one of the last coal-powered plants to be built in the U.S.
Like many Texas kids, Latimer came from an oil family, and got his first jobs in the oil and gas industry before realizing that the world was going to be switching to renewables and the oil industry — along with the friends and family he knew — could be left high and dry.
It’s one reason he started working on Fervo, the entrepreneur said.
“What’s most important, from my perspective, since I started my career in the oil and gas industry, is providing folks that are part of the energy transition on the fossil fuel side to work in the clean energy future,” Latimer said. “I’ve been able to go in and hire contractors and support folks that have been out of work or challenged because of the oil price crash… And I put them to work on our rigs.”

When the Biden administration talks about finding jobs for employees in the hydrocarbon industry as part of the energy transition, this is exactly what they’re talking about.
And geothermal power is no longer as constrained by geography, so there are a lot of abundant resources to tap and the potential for high-paying jobs in areas that are already dependent on geological services work, Latimer said (late last year, Vox published a good overview of the history and opportunity presented by the technology).
“A large percentage of the world’s population actually lives next to good geothermal resources,” Latimer said. “[There are] 25 countries today that have geothermal installed and producing and another 25 where geothermal is going to grow.”
Geothermal power production actually has a long history in the Western U.S. and in parts of Africa where naturally occurring geysers and steam jets pouring from the earth have been obvious indicators of good geothermal resources, Latimer said.
“Fervo’s technology unlocks a new class of geothermal resource that is ready for large-scale deployment. Fervo’s geothermal systems use novel techniques, including horizontal drilling, distributed fiber optic sensing and advanced computational modelling, to deliver more repeatable and cost effective geothermal electricity,” Latimer wrote in an email. “Fervo’s technology combines with the latest advancements in Organic Rankine Cycle generation systems to deliver flexible, 24/7 carbon-free electricity.”
Initially developed with a grant from the TomKat Center at Stanford University and a fellowship funded by Activate.org at the Lawrence Berkeley National Lab’s Cyclotron Road division, Fervo has gone on to score funding from the DOE’s Geothermal Technology Office and ARPA-E to continue work with partners like Schlumberger, Rice University and the Berkeley Lab.
The combination of new and old technology is opening vast geographies to the company to potentially develop new projects.
Other companies are also looking to tap geothermal power to drive a renewable power-generation development business. Those are startups like Eavor, which has the backing of energy majors like bp Ventures, Chevron Technology Ventures, Temasek, BDC Capital, Eversource and Vickers Venture Partners; and other players including GreenFire Energy and Sage Geosystems.
Demand for geothermal projects is skyrocketing, opening up big markets for startups that can nail the cost issue for geothermal development. As Latimer noted, from 2016 to 2019 there was only one major geothermal contract, but in 2020 there were 10 new major power purchase agreements signed by the industry.
For all of these projects, cost remains a factor. Contracts that are being signed for geothermal that are in the $65 to $75 per megawatt range, according to Latimer. By comparison, solar plants are now coming in somewhere between $35 and $55 per megawatt, as The Verge reported last year.
But Latimer said the stability and predictability of geothermal power made the cost differential palatable for utilities and businesses that need the assurance of uninterruptible power supplies. As a current Houston resident, the issue is something that Latimer has an intimate experience with from this year’s winter freeze, which left him without power for five days.
Indeed, geothermal’s ability to provide always-on clean power makes it an incredibly attractive option. In a recent Department of Energy study, geothermal could meet as much as 16% of the U.S. electricity demand, and other estimates put geothermal’s contribution at nearly 20% of a fully decarbonized grid.
“We’ve long been believers in geothermal energy but have waited until we’ve seen the right technology and team to drive innovation in the sector,” said Ion Yadigaroglu of Capricorn Investment Group, in a statement. “Fervo’s technology capabilities and the partnerships they’ve created with leading research organizations make them the clear leader in the new wave of geothermal.”

Swedish battery manufacturer Northvolt receives a $14 billion order from VW
Northvolt, the Swedish battery manufacturer which raised $1 billion in financing from investors led by Goldman Sachs and Volkswagen back in 2019, has signed a massive $14 billion battery order with VW for the next 10 years.
The big buy clears up some questions about where Volkswagen will be getting the batteries for its huge push into electric vehicles, which will see the automaker reach production capacity of 1.5 million electric vehicles by 2025.
The deal will not only see Northvolt become the strategic lead supplier for battery cells for Volkswagen Group in Europe, but will also involve the German automaker increasing its equity ownership of Northvolt.
As part of the partnership agreement, Northvolt’s gigafactory in Sweden will be expanded and Northvolt agreed to sell its joint venture share in its Salzgitter, Germany factory to Volkswagen as the car maker looks to build up its battery manufacturing efforts across Europe, the companies said.
The agreement between Northvolt and VW brings the Swedish battery maker’s total contracts to $27 billion in the two years since it raised its big $1 billion cash haul.
“Volkswagen is a key investor, customer and partner on the journey ahead and we will continue to work hard with the goal of providing them with the greenest battery on the planet as they rapidly expand their fleet of electric vehicles,” said Peter Carlsson, the co-founder and chief executive of Northvolt, in a statement.
Northvolt’s other partners and customers include ABB, BMW Group, Scania, Siemens, Vattenfall and Vestas. Together these firms comprise some of the largest manufacturers in Europe.
Back in 2019, the company said that its cell manufacturing capacity could hit 16 gigawatt hours and that it had sold its capacity to the tune of $13 billion through 2030. That means that the Volkswagen deal will eat up a significant portion of expanded product lines.
Founded by Carlsson, a former executive at Tesla, Northvolt’s battery business was intended to leapfrog the European Union into direct competition with Asia’s largest battery manufacturers — Samsung, LG Chem and CATL.
Back when the company first announced its $1 billion investment round, Carlsson had said that Northvolt would need to build up to150 gigawatt hours of capacity to hit targets for 2030 electric vehicle sales.
The plant in Sweden is expected to hit at least 32 gigawatt hours of production, thanks in part to backing by the Swedish pension fund firms AMF and Folksam and Ikea-linked IMAS Foundation, in addition to the big financial partners Volkswagen and Goldman Sachs.
Northvolt has had a busy few months. Earlier in March the company announced the acquisition of the Silicon Valley-based startup company Cuberg.
That acquisition gave Northvolt a foothold in the U.S. and established the company’s advanced technology center.
The acquisition also gives Northvolt a window into the newest battery chemistry that’s being touted as a savior for the industry — lithium metal batteries.
Cuberg spun out of Stanford University back in 2015 to commercialize what the company called its next-generation battery, combining a liquid electrolyte with a lithium metal anode. The company’s customers include Boeing, BETA Technologies, Ampaire and VoltAero, and it was backed by Boeing HorizonX Ventures, Activate.org, the California Energy Commission, the Department of Energy and the TomKat Center at Stanford.
Cuberg’s cells deliver 70% increased range and capacity versus comparable lithium ion cells designed for electric aviation applications. The two companies hope they can apply the technology to Northvolt’s automotive and industrial product portfolio with the ambition to industrialize cells in 2025 that exceed 1,000 Wh/L, while meeting the full spectrum of automotive customer requirements, according to a statement.
“The Cuberg team has shown exceptional ability to develop world-class technology, proven results and an outstanding customer base in a lean and efficient organization,” said Peter Carlsson, CEO and co-founder, Northvolt in a statement. “Combining these strengths with the capabilities and technology of Northvolt allows us to make significant improvements in both performance and safety while driving down cost even further for next-generation battery cells. This is critical for accelerating the shift to fully electric vehicles and responding to the needs of the leading automotive companies within a relevant time frame.”

La Haus is bringing US tech services to Latin America’s real estate market
The alchemy for a successful startup can be hard to parse. Sometimes, it’s who you know. Sometimes it’s where you go to school. And sometimes it’s what you do. In the case of La Haus, a startup that wants to bring U.S. tech-enabled real estate services to the Latin American real estate market, it’s all three.
The company was founded by Jerónimo Uribe and Rodrigo Sánchez Ríos, both graduates of Stanford University who previously founded and ran Jaguar Capital, a Colombian real estate development firm that had built over $350 million worth of retail and residential projects in the country.
Uribe, the son of the controversial Colombian President Daniel Uribe (who has been accused of financing paramilitary forces during Colombia’s long-running civil war and wire-tapping journalists and negotiators during the peace talks to end the conflict) and Sánchez Ríos, a former private equity professional at the multi-billion-dollar firm Lindsay Goldberg, were exposed to the perils and promise of real estate development with their former firm.
Now the two entrepreneurs are using their know-how, connections and a new technology stack to streamline the home-buying process.
It’s that ambition that caught the attention of Pete Flint, the founder of Trulia and now an investor at the venture capital firm NFX. Flint, an early investor in La Haus, saw the potential in La Haus to help the Latin American real estate market leapfrog the services available in the U.S. Spencer Rascoff, the co-founder of Zillow, also invested in the company.
“Latin America is very early on in its infancy of having really professional agents and really professional brokerages,” said Flint.
La Haus guides home buyers through every stage of the process, with its own agents and salespeople selling properties sourced from the company’s developer connections.
“The average home in the U.S. sells in six weeks or less,” said La Haus chief financial officer Sánchez Ríos in an interview. “That timing in Latin America is 14 months. That’s the dramatic difference. There is no infrastructure in Latin America as a whole.”
La Haus began by reaching out to the founders’ old colleagues in the real estate development industry and started listing new developments on its service. Now the company has a mix of existing and new properties for sale on its site and an expanded geographic footprint in both Colombia and Mexico.
“We have a portal… that acts as a lead-generating machine,” said Sánchez Ríos. “We aggregate listings, we vet them. We focus on new developers.”
The company has about 500 developers using the service to list properties in Colombia and another 200 in Mexico. So far, the company has facilitated more than 2,000 transactions through its platform in three years.
“Real estate now is turning fully digital and also in this market professionalizing,” said Flint. “The publicly traded online real estate companies are approaching all-time highs. People are just prizing the space that they spend their time in… the technologies from VR and digital walkthroughs to digital closes become not just a nice to have but a necessity. “
Capitalizing on the open field in the market, La Haus recently closed on $10 million in financing led by Kaszek Ventures, one of the leading funds in Latin America. That funding will be used to accelerate the company’s geographic expansion in response to increasing demand for digital solutions in response to the COVID-19 epidemic.
“Because of Covid-19, consumers’ willingness to conduct real estate transactions online has gone through the roof,” said Sánchez Ríos, in a statement. “Fortunately we were in the position to enable that, and we expect to see a permanent shift online in how people conduct all, or at least most, of the home-buying process. This funding gives us ample runway to build the end-to-end real estate experience for the post-Covid Latin America.”
Joining NFX, Rascoff, and Kaszek Ventures are a slew of investors, including Acrew Capital, IMO Ventures and Beresford Ventures. Entrepreneurs like Nubank founder David Velez; Brian Requarth, the founder of Vivareal (now GrupoZap); and Hadi Partovi, CEO and founder of Code.org, also participated in the financing.
“We backed La Haus because we saw many of the same ingredients that resulted in a fantastic outcome for many of our successful companies: A world-class team with complementary skills; a huge addressable market; and an almost religious zeal by the founders to solve a big problem with technology,” said Hernan Kazah, co-founder and managing partner of Kaszek Ventures.

Marietje Schaake is ‘very concerned about the future of democracy’

In the ten years she spent as a member of the European Parliament, Marietje Schaake became one of Brussels’ leading voices on technology policy issues.
A Dutch politician from the centrist-liberal Democrats 66 party, Schaake has been called “Europe’s most wired” politician. Since stepping down at the last European Parliament elections in 2019, she has doubled down with her work on cyber policy, becoming president of the CyberPeace Institute in Geneva and moving to the heart of Silicon Valley, where she has joined Stanford University as both the International Director of Policy at Stanford’s Cyber Policy Center, as well as an International Policy Fellow at its Institute for Human-Centered Artificial Intelligence.
I spoke with her about her top cyber policy concerns, the prospects of greater U.S.-EU cooperation on technology and much more.
Can you tell me about your journey from MEP in Brussels to think tank in academia?
There were a variety of reasons why I thought a third term was not the best thing for me to do. I started thinking about what would be a good way to continue, focusing on the fight for justice, for universal human rights and increasingly for the rule of law. A number of academic institutions, especially in the U.S. reached out, and we started a conversation about what the options might be, what I thought would be worthwhile. [My goal] was to understand where tech is going and what does it mean for society, for democracy, for human rights and the rule of law? But also how do the politics of Silicon Valley work?
I feel like there’s a huge opportunity, if not to say gap, on the West Coast when it comes to a policy shop — both to scrutinize policy that the companies are making and to look at what government is doing because Sacramento is super interesting.
So from a policy perspective, what areas of tech are you thinking about most?
I’m very concerned about the future of democracy in the broadest sense of the word. I feel like we need to understand better how the architecture of information flows and how it impacts our offline democratic world. The more people get steered in a certain direction, the more the foundations of actual liberalism and liberal democracy are challenged. And I feel like we just don’t look at that enough.

As wildfire season approaches, AI could pinpoint risky regions using satellite imagery
The U.S. has suffered from devastating wildfires over the last few years as global temperatures rise and weather patterns change, making the otherwise natural phenomenon especially unpredictable and severe. To help out, Stanford researchers have found a way to track and predict dry, at-risk areas using machine learning and satellite imagery.
Currently the way forests and scrublands are tested for susceptibility to wildfires is by manually collecting branches and foliage and testing their water content. It’s accurate and reliable, but obviously also quite labor intensive and difficult to scale.
Fortunately, other sources of data have recently become available. The European Space Agency’s Sentinel and Landsat satellites have amassed a trove of imagery of the Earth’s surface that, when carefully analyzed, could provide a secondary source for assessing wildfire risk — and one no one has to risk getting splinters for.
This isn’t the first attempt to make this kind of observation from orbital imagery, but previous efforts relied heavily on visual measurements that are “extremely site-specific,” meaning the analysis method differs greatly depending on the location. No splinters, but still hard to scale. The advance leveraged by the Stanford team is the Sentinel satellites’ “synthetic aperture radar,” which can pierce the forest canopy and image the surface below.
“One of our big breakthroughs was to look at a newer set of satellites that are using much longer wavelengths, which allows the observations to be sensitive to water much deeper into the forest canopy and be directly representative of the fuel moisture content,” said senior author of the paper, Stanford ecoydrologist Alexandra Konings, in a news release.
The team fed this new imagery, collected regularly since 2016, to a machine learning model along with the manual measurements made by the U.S. Forest Service. This lets the model “learn” what particular features of the imagery correlate with the ground-truth measurements.
They then tested the resulting AI agent (the term is employed loosely) by having it make predictions based on old data for which they already knew the answers. It was accurate, but most so in scrublands, one of the most common biomes of the American west and also one of the most susceptible to wildfires.
You can see the results of the project in this interactive map showing the model’s prediction of dryness at different periods all over the western part of the country. That’s not so much for firefighters as a validation of the approach — but the same model, given up to date data, can make predictions about the upcoming wildfire season that could help the authorities make more informed decisions about controlled burns, danger areas and safety warnings.
The researchers’ work was published in the journal Remote Sensing of Environment.

Edtech startups prepare to become ‘not just a teaching tool but a necessity’
As Stanford, Princeton, Columbia and others shutter classrooms to limit the coronavirus outbreak, college educators around the country are clambering to move their classes online.
At the same time, tech companies that enable remote learning are finding a surge in usage and signups. Zoom Video Communications, a videoconferencing company, has been crushing it in the stock market, and Duolingo, a language teaching app, has had 100% user growth in the past month in China, citing school closures as one factor.
But Kristin Lynn Sainani, an associate professor of epidemiology and population health at Stanford, has a fair warning to those making the shift: scrappiness has its setbacks.
“[The transition to online] is not going to be well planned when you’re doing it to get your class done tomorrow,” said Sainani, who has been teaching online classes since 2013. “At this point, professors are going to scramble to do the best they can.”
As the outbreak spreads and universities respond, can edtech startups help legacy institutions rapidly adopt online teaching services? And perhaps more tellingly, can they do so in a seamless way?

Lumineye helps first responders identify people through walls
Any first responder knows that situational awareness is key. In domestic violence disputes, hostage rescue or human trafficking situations, first responders often need help determining where humans are behind closed doors.
That’s why Megan Lacy, Corbin Hennen and Rob Kleffner developed Lumineye, a 3D-printed radar device that uses signal analysis software to differentiate moving and breathing humans from other objects, through walls.
Lumineye uses pulse radar technology that works like echolocation (how bats and dolphins communicate). It sends signals and listens for how long it takes for a pulse to bounce back. The software analyzes these pulses to determine the approximate size, range and movement characteristics of a signal.
On the software side, Lumineye’s app will tell a user how far away a person is when they’re moving and breathing. It’s one dimensional, so it doesn’t tell the user whether the subject is to the right or left. But the device can detect humans out to 50 feet in open air; that range decreases depending upon the materials placed in between, like drywall, brick or concrete.
One scenario the team gave to describe the advantages of using Lumineye was the instance of hostage rescue. In this type of situation, it’s crucial for first responders to know how many people are in a room and how far away they are from one another. That’s where the use of multiple devices and triangulation from something like Lumineye could change a responding team’s tactical rescue approach.
Machines that currently exist to make these kind of detections are heavy and cumbersome. The team behind Lumineye was inspired to manufacture a more portable option that won’t weigh down teams during longer emergency response situations that can sometimes last for up to 12 hours or overnight. The prototype combines the detection hardware with an ordinary smartphone. It’s about 10 x 5 inches and weighs 1.5 pounds.
Lumineye wants to grow out its functionality to become more of a ubiquitous device. The team of four is planning to continue manufacturing the device, selling it directly to customers.
Lumineye’s device can detect humans through walls using radio frequencies
Lumineye has just started its pilot programs, and recently spent a Saturday at a FEMA event testing out the the device’s ability to detect people covered in rubble piles. The company was born out of the Boise, Idaho cohort of Stanford’s Hacking4Defense program, a course meant to connect Silicon Valley innovations with the U.S. Department of Defense and Intelligence Community. The Idaho-based startup is graduating from Y Combinator’s Summer 2019 class.

Nowports raises $5.3 million to become Latin America’s digital shipping answer to Flexport
Nowports, a developer of software and services to track freight shipments from ports to destinations across Latin America, has aims to become the regional answer to Flexport’s billion-dollar digital shipping business.
Almost 54 million containers are imported and exported from Latin America each year, and nearly half of them are either delayed or lost due to mismanagement.
Nowports is pitching shippers on its digital management software to keep track of each container, and has signed on a number of leading venture capital firms to fulfill its mission.
The Monterrey, Mexico-based company raised $5.3 million in its seed round of financing. The round was led by Base10 and Monashees, with participation from Y Combinator and additional investors like Broadhaven, Soma Capital, Partech, Tekton and Paul Buchheit.
“In Nowports we saw a very strong combination: well prepared and ambitious team using technology to help thousands of customers to improve their importing and exporting processes. By adding efficiency, reliability, and transparency to change a multi-billion dollar industry, Nowports has been able to attract many clients that saw significant improvements in their daily routines by using the solution” said Caio Bolognesi, general partner from Monashees, in a statement.
The company said it would use the money to expand into new markets, grow its team and integrate with more companies involved in the (very fragmented) Latin American logistics industry. It’s a market that needs a range of better logistics technologies.
“Even though over 90% of the world’s trade is carried by sea, the most cost-effective way to move goods en masse, there has yet to be a solution that’s able to connect suppliers, customs brokers, carriers and transportation companies to provide an efficient and reliable service,” said Maximiliano Casal, founder and chief executive of Nowports, in a statement. “This is why we launched Nowports, combining our 10 years of industry expertise to fill this void and are currently working with over 40 customers in the region and growing.”
The company now has offices in Chile and Uruguay, and is planning to expand to Brazil, Colombia and Peru.
“With platforms, algorithms with AI and integrations, our platform allows companies to take control of their shipments and plan and predict the best timing to move the freight based on the needs of their own company,” said Alfonso De Los Rios, founder and CTO of Nowports.
As the company looks to expand, it has a strategic road map it can follow in the growth of Flexport, the Silicon Valley startup that has become a billion-dollar business by applying technology to the outdated shipping industry.
The two co-founders of Nowports met at a program at Stanford University, with De Los Rios hailing from a family with deep ties to the shipping industry. He and Casal linked up and the two began plotting a way to make the deeply inefficient industry more modern and transparent. To familiarize himself with the market for which he’d be developing a technology, Casal worked in a freight forwarder in Kansas City that had been operating for more than 30 years.
In all, freight providers are getting paid nearly $40 billion per year to move freight into Latin America.
“Alfonso and Max are the ideal founders we look to invest in as they are industry experts and passionate about evolving the industry using technology and automation,” said Adeyemi Ajao, general partner from Base10. “We are proud to be investors in Nowports alongside our friends at Monashees and look forward to watching the company’s continued growth.”
