Exowatt, Inc.

Exowatt is a next-generation renewable energy company based in Miami, Florida, that's tackling one of the biggest challenges facing AI infrastructure today: reliable, round-the-clock power. Founded in 2023 by Hannan Happi and Jack Abraham, Exowatt has developed the Exowatt P3, a groundbreaking modular energy system that captures solar energy, stores it as heat in long-duration thermal batteries, and converts it to electricity on demand - delivering up to 24 hours of dispatchable power daily.

The company's mission is clear: make sustainable renewable energy always available and almost free. Unlike traditional solar that only generates power when the sun shines, Exowatt's technology solves this intermittency problem by storing thermal energy efficiently, enabling data centers and energy-intensive industries to access clean baseload power without relying on grid interconnection or expensive electrochemical batteries. Backed by investors including Andreessen Horowitz, Sam Altman, and Felicis, Exowatt has raised over $140 million and is rapidly scaling manufacturing to meet the surging demand for sustainable power near AI data centers nationwide.
