The man behind Tesla’s Powerwall is now pitching an all-in-one power management system for homes

Published September 19, 2019

Arch Rao, the former head of product at Tesla who was behind the company’s Powerwall home energy storage is system, is back with a new company pitching energy management and efficiency for homes.

Span is looking to upgrade the electrical fuse box for homes with a digital system that integrates into the existing circuit breaker technology that has been the basis for home energy management for at least a century.

Rao and his team are looking to make integrating renewable power, energy storage and electric vehicles easier for homeowners by redesigning the electrical panel for modern energy needs.

“We packaged the metering controls and compute between the bus bar and the breaker,” says Rao. “Energy flows through the panel through a breaker bar and the breaker bar has tabs that you slot your breakers into… that tab is usually a conductor. We have designed a digital sub-assembly that packages current metering, voltage measurement and the ability to turn each circuit on or off.”

The technology is meant to be sold through channels like solar energy installers or battery installers. The company already has plans to integrate its power management devices with energy storage systems like the ones available from LG .

Initially, Span expects to be selling its products in states like California and Hawaii where demand for solar installations is strong and homeowners have significant benefits available to them for installing renewable energy and energy efficiency systems.

For homeowners, the new power management system means that they have control over which parts of the home would be powered in the event of an outage. The company’s technology connects the entire home to a renewable system. Using existing technologies, installers have to set up a separate breaker and rewire certain areas of the home to receive the power generated by a renewable energy system, Rao says.

That control is handled through a consumer app available to download on mobile devices.

Span is backed by a slew of early investors, including Wireframe Ventures, Wells Fargo Strategic Capital, Ulu Ventures, Hardware Club, Energy Foundry, Congruent Ventures and 1/0 Capital, and intends to raise fresh cash before the end of the year. Rao said the round would be “in the low double digits” of millions.

Bellwether Coffee, ‘the fastest-growing company in coffee,’ raises $40M Series B

Published September 4, 2019

There’s an arms race in retail to produce better coffee, and one startup, Bellwether Coffee, thinks it has the solution for retailers to sell the very best beans.

The business, headquartered in Berkeley, is today announcing a $40 million Series B financing led by DBL Partners and SolarCity co-founders Peter and Lyndon Rive. The round brings its total funding to $56 million, including a $10 million Series A last summer.

The hardware and software business manufactures tech-enabled zero-emission commercial coffee roasters designed to sit in cafes, grocery stores, on college campuses and any other place people buy coffee. Purchase of a roaster, which are sold for $75,000 or leased for $1,000 per month, comes with access to an online marketplace for coffee beans. The goal is to give coffee shops the power to roast their own beans, forgoing the middle men that have historically sold wholesale pre-roasted beans at a premium to cafes around the world.

“We want to create this connected coffee experience from the farm in Ethiopia all the way to the roaster at the cafe and the customer,” Bellwether chief executive officer Nathan Gilliland tells TechCrunch.

With roughly 140 customers, Bellwether plans to expand manufacturing capabilities and grow its customer-facing team with the infusion of venture capital funding. After growing revenues 6x in 2019, the startup is also unlocking its global ambitions, with launches in Southeast Asia and Europe scheduled for next year.

Gilliland credits the company’s growth to a larger movement at play: The “premiumization of coffee,” in which consumers are in search of higher quality cups of joe.

“You saw it happen with wine, you saw it in craft beer,” he said. “You were drinking Bud Light and now you’re drinking craft beer. You see it in higher-end grocery stores pushing out these products; it’s the premiumization of the category.”

“Thirty years ago, everyone drank Folgers, then Starbucks changed how everyone thought about coffee in the 80s, then Blue Bottle took it to the next step and that’s the backdrop,” he added.

Bellwether was founded in 2013 by Ricardo Lopez. The company is also backed by FusionX, Congruent Ventures, Coffee Bell, Tandem Capital, Spindrift Equities, XN Ventures, Balius Partners and Hardware Club.
