Fractile
UK AI-inference-chip startup (SRAM-based, DRAM-less architecture) backed by Founders Fund and the NATO Innovation Fund.
Fractile, founded in 2022 by Oxford engineer Walter Goodwin, builds AI inference chips using a DRAM-less, SRAM-based architecture aimed at reducing inference latency and cost. The company emerged from stealth in 2024 after a $15M seed round (co-led by Kindred Capital, the NATO Innovation Fund, and Oxford Science Enterprises) and closed a $220M Series B in May 2026 led by Accel, Factorial Funds, and Founders Fund, at a valuation near $1B, for total funding of roughly $235M. The company is pre-revenue and has not yet shipped silicon.
