Etched is a Cupertino-based semiconductor startup, founded in 2022 by Harvard dropouts Gavin Uberti, Chris Zhu, and Robert Wachen. The company is building frontier inference clusters. Their rack-scale systems leverage two core architectures, Low Voltage Inference and Cluster Scale Memory, so frontier models can run performantly across both prefill and decode workloads.

Etched has raised $800M in funding, with investors including Stripes, Ribbit Capital, Positive Sum, and Primary Venture Partners.
