Overview
Etched was founded in 2022 by Gavin Uberti, Robert Wachen and Chris Zhu, who left Harvard to build it. The founding premise was unusually stark: rather than build a flexible accelerator, hard-wire the transformer architecture directly into the chip. A processor that can only do one thing can do that thing with far less silicon spent on generality — no instruction scheduling for operations it will never run, no datapaths for models it will never serve.
The corresponding risk was equally stark, and Etched's critics named it immediately: a chip that runs only transformers is worthless if the field moves past transformers. For its first years the company was as well known for that objection as for its technology.
Etched emerged from stealth on 30 June 2026 stating that it had raised $800 million, had working silicon, and held more than $1 billion in signed customer contracts. Three weeks later, on 23 July 2026, it closed a $300 million Series C led by Sequoia Capital at a $10.3 billion valuation — double its December 2025 valuation of $5 billion, and described by Sequoia as the highest valuation at which it has led a Series C.
