femtoAI

femtoAI develops a full-stack edge AI inference platform that pairs sparse neural models with sparsity-aware silicon for wearables, appliances, robotics, and autonomous systems. Formerly Femtosense and founded by Stanford Brains in Silicon Lab researchers, the company sells ready-to-deploy models, an SDK, and its Sparse Processing Unit (SPU) accelerator.

The platform targets extreme-edge devices that need higher capacity, lower latency, and far less energy than conventional GPUs or dense NPUs. Public leadership includes CEO Sam Fok, CTO Alex Neckar, and Chief AI Officer Scott Reid, with investors spanning Fine Structure Ventures, J2 Ventures, Kleiner Perkins, and others.
