We built this because our own solar was bleeding money.
Then we realized every solar home in California was doing the same thing.
In 2023, California changed the rules. Export payments dropped roughly 75% overnight under NEM 3.0. Akshat's family was losing money every month on solar they couldn't use.
Akshat wrote the software that routes wasted solar to where it's actually needed — automatically, across any solar inverter and any EV, with no new hardware.
That software became Tesphase.

Every kilowatt-hour of solar that gets wasted is a failure of software, not hardware.
The panels work. The batteries exist. The missing piece is an orchestration layer that connects them.
Tesphase is that layer — vendor-agnostic, hardware-free, and learning from every home it touches.
