Heron Power raises $140 million to revolutionize data center efficiency
Heron Power, founded by ex-Tesla exec Drew Baglino, just raised $140 million in Series B funding led by Andreessen Horowitz and Breakthrough Energy Ventures.
This follows a $38 million Series A last year, with other big names like Capricorn Investment Group and Energy Impact Partners joining in.
They're making the Heron Link
They're making the Heron Link—a modular solid-state transformer that ditches old-school iron cores.
It shrinks data center power gear by 70%, cuts out bulky legacy parts, and hits 98.6% DC-to-MV efficiency for solar and storage and 98.5% MV-to-rack efficiency for data centers.
Basically: smaller, smarter, greener power tech.
Factory plans in the works
Heron Power plans to open a factory aiming for 40 gigawatts of annual output (that's about 10-15% of global supply outside China).
They'll start pilot production in early 2027 and ramp up from there—so expect more efficient data centers and cleaner energy soon.
