Etched Raises $300 Million Series C at $10.3 Billion Valuation Led by Sequoia

AI inference chip startup Etched raised $300 million in a Series C funding round at a $10.3 billion valuation, doubling its worth since December. Sequoia led the investment, with Andreessen Horowitz, Jane Street, Argo, and SK Hynix participating.

Co-founders Gavin Uberti, Robert Wachen, and Chris Zhu dropped out of Harvard in 2022 to build a complete inference hardware stack from scratch, encompassing new chips, boards, interconnects, and racks. The company also recently opened an 80,000-square-foot, 10-MW production facility, as specialized silicon enters the market and must prove it can beat general GPUs in real inference clusters.

I remember going on a road trip with @UbertiGavin and @robertwachen right after they dropped out of Harvard, and it was so clear that they would become generational founders even then. @Etched was deeply contrarian early on. Most of the to
