Inference chip startup Fractile raises $720M Series C six months after its $220M Series B

Fractile, founded in summer 2022 by Oxford PhD Walter Goodwin, announced a $720M Series C led by Thrive Capital, Founders Fund, Lightspeed and Redpoint — just six months after a $220M Series B. The company bets that today's chips starve the most capable AI models of memory bandwidth, and that a large dividend awaits faster inference. The accompanying interview pairs Goodwin with Sir Robin Saxby, ARM's founding CEO, who built the UK's biggest chip success story from 12 engineers in a pub.
