Founded in 2022, Fractile develops chips and systems aimed at dramatically speeding up inference for frontier AI models. The company’s thesis is that time-to-output and inference unit economics—particularly memory bandwidth limits—are the next major bottlenecks as models generate increasingly long outputs. Fractile is working across AI research, chip microarchitecture, and foundry process innovation to reduce inference latency and cost. Its technology targets workloads that can require tens of millions of tokens and seeks to enable new, longer-running AI tasks by making faster inference economically viable. The company is expanding its team and hiring across London, Bristol, San Francisco, and Taipei as it scales development.
