Light Raises $46 Million to Sell Other Brands' Electricity

Light raised $46 million in a Series A round announced Sept. 1, led by Matrix with Activate Capital joining as a new investor, according to the company's own announcement. Existing backers Spark Capital, Mischief, Gigascale Capital, MCJ and BoxGroup also participated. The round brings Light's total funding to about $60 million, and the company said its full capital base, including a credit facility, now exceeds $100 million.

Light, founded in 2023 by chief executive Baker Shogry, a former head of product at Plaid, operates as what the company calls an API platform for electricity: partner brands design their own retail power plans and launch them in about two weeks, while Light handles the regulatory licensing, wholesale power procurement, billing and grid operations underneath, per its announcement. Adam Compain, Light's head of go-to-market and the former CEO of ClearMetal before its 2021 acquisition, leads that commercial build-out, according to MCJ's investor writeup of the round.

The customer list is the pitch

Light's partners include Palmetto, GoodLeap, Emporia, Public Grid, Lunar Energy and Moved, and the company says its network now touches more than 30 percent of U.S. residential solar sales, over 500,000 homeowners and more than 1 million multi-family housing units, per its announcement. Every new electricity brand that launched in Texas in the first half of 2026 ran on Light's platform, the company said, and its run-rate revenue grew tenfold over the 12 months ending in mid-2026. MCJ, one of the round's backers, said in its newsletter that it is pricing Light against infrastructure platforms like Stripe, Plaid and Twilio rather than against retail energy competitors, on the theory that the enablement layer, not the electricity itself, is where the value sits.

Why the round is aimed past Texas

Light said it will use the new capital to expand outside Texas into the PJM Interconnection, the transmission territory covering New Jersey, Pennsylvania and Illinois, and to grow its regulatory and energy-procurement teams accordingly, per its announcement. The company also named hyperscale data center developers as a specific target for its business-development pipeline, the same demand source Oracle cited when it tripled its own GPU deliveries to 300,000 units and 850 megawatts of capacity in its most recent quarter. Light did not disclose a valuation for the round, a gap it shares with fellow September Series A recipient Graph AI, whose $13.3 million round also went unpriced publicly.

The $100 million capital-base figure includes debt, which is standard for a company that has to prepay wholesale power markets before it collects a single customer bill; it is not a valuation and Light did not offer one. What the round actually tests is whether the sell-power-under-your-own-brand pitch that worked for solar installers and proptech firms extends to data center operators with far larger, far less predictable load profiles than a homeowner's rooftop panels. Light's next disclosed number to watch is how many megawatts, not how many households, show up in its PJM filings once it is licensed to operate there.
