DateStageInvestorsRaisedDeal Summary
Feb 2026Series BAndreessen Horowitz (lead); Breakthrough Energy Ventures (lead); Gigascale Capital; Valor Equity Partners; Energy Impact Partners; Capricorn Investment Group$140MHeron Power, an energy infrastructure startup founded in 2025 by former Tesla executive Drew Baglino, develops solid-state transformers under the Heron Link product for critical energy projects including utility-scale solar, energy storage, battery sites, and AI data centers. The technology addresses grid bottlenecks by offering faster deployment, higher reliability, flexibility, and domestic U.S. manufacturing amid rising electricity demand. The Series B round closed on February 18, 2026, raising $140 million co-led by Andreessen Horowitz’s American Dynamism Fund and Breakthrough Energy Ventures, with participation from Capricorn Investment Group, Energy Impact Partners, Gigascale Capital, and Valor Atreides AI Fund. This follows a $38 million Series A in May of the prior year. Funding will build a highly automated U.S. manufacturing facility capable of producing 40 gigawatts of Heron Link transformers annually, equivalent to 10-15% of non-China global production or half of Texas's peak power demand, with pilot production starting early 2027 and full scale in late 2027. Heron Power has strong early traction, identifying over 40 gigawatts of customer interest through product-led partnerships and securing 50 gigawatts of orders from customers like Intersect Power and Crusoe. Data centers represent about one-third of its business, with the rest split between solar and grid-scale batteries. The company targets developers needing solutions for deployment timelines, reliability, and supply chains, positioning against legacy transformers amid shortages and an aging grid. Investors highlight Heron's expertise in power electronics, commercialization, and scaling production to modernize the grid for AI-driven loads. While competition exists in solid-state transformers, Heron's U.S. focus, Baglino's experience, and customer commitments provide advantages. An earlier February 3 report noted the round targeting over $100 million, potentially up to $200 million at a $1 billion valuation, but final terms confirmed only the $140 million raise without valuation details.
May 2025Series ACapricorn Investment Group (lead); Gigascale Capital; Breakthrough Energy Ventures; Valor Equity Partners; Powerhouse Ventures; Energy Impact Partners; Zachary Kirkhorn$38MHeron Power is an energy infrastructure company founded by Drew Baglino, a former Tesla executive, developing solid-state transformer technology designed to modernize the electrical grid. The company's primary product, Heron Link, is a modular solid-state transformer that enables renewable energy, storage, and data center developers to directly connect to medium-voltage transmission infrastructure, replacing century-old analog transformer models with faster, more compact, and software-integrated solutions. On May 29, 2025, Heron Power closed a $38 million Series A funding round led by Capricorn Investment Group, with participation from Breakthrough Energy Ventures, Energy Impact Partners, Gigascale Capital, Powerhouse Ventures, Valor Equity Partners, Tesla co-founder JB Straubel, and former Tesla CFO Zach Kirkhorn. The total funding raised through the Series A brought cumulative capital to $43 million. The Series A proceeds accelerate team expansion and development of Heron Link, with the company targeting initial deployments in early 2027 and already collaborating with leading energy and data center developers. In February 2026, Heron Power announced a $140 million Series B financing round co-led by Andreessen Horowitz's American Dynamism Fund and Breakthrough Energy Ventures, bringing total funding to $183 million. The Series B capital will fund a highly automated U.S. manufacturing facility capable of producing 40 gigawatts of solid-state transformers annually, with full-scale production expected in the second half of 2027. The company has already secured 50 gigawatts of orders and is initially targeting solar farms, battery storage sites, and data center campuses, demonstrating the technology's applicability to the growing electricity demand driven by renewable energy and artificial intelligence infrastructure expansion.
