About
Exowatt is a clean energy startup founded in 2023 by Hannan Happi and Jack Abraham (Atomic CEO), developing modular, dispatchable solar systems designed to deliver reliable 24/7 power for AI infrastructure. Its flagship P3 platform stores solar energy as heat and converts it to electricity on demand — including overnight — eliminating the intermittency problem that has limited solar adoption for energy-intensive data centers. The company uses a U.S.-anchored supply chain built on domestically sourced materials, limiting rare earth, tariff, and Foreign Entity of Concern (FEOC) exposure while qualifying for Investment Tax Credit incentives.
