Why we invested

We backed a power company built around distributed batteries and software. Each home battery can protect a household while helping the wider grid manage changing demand. Our April 2025 investment memo described the opportunity to build a utility from the customer outward.

The thesis depends on execution across the whole system: battery design, manufacturing, permitting, installation, and orchestration. Zach Dell and Justin Lopas brought together engineers and operators with experience at Tesla, SpaceX, and Anduril to tackle that work. a16z co-led the Series B and participated in the subsequent Series C and Series D.
