Terafab

The most epic chip-building effort ever

Watch NowWatch Join UsJoin

Terafab will close the gap between today's chip production and the future's demand —
a future among the stars.

The Kardashev Scale

We aspire to be a galactic civilization

  1. Type IHarness all of the energy on a planet
  2. Type IIHarness all of the energy from a star
  3. Type IIIHarness all of the energy in a galaxy

Harnessing the power of the Sun

  • Maximize utilization of the Sun's energy
  • Produce AI chips at scale
  • Unlock interplanetary travel

We're builders.
We've done the impossible before.
