What does Parasma do?
Parasma is a San Francisco biocomputing startup that writes algorithms to train live human brain cells to act as a computing substrate for AI workloads. The founder previously got cultured human neurons to play Doom, and the company's claimed edge is the training methodology rather than proprietary wetware hardware. It is a Y Combinator Summer 2026 company, solo-founded and pre-product as of mid-2026.
