About Zibra Labs

We build distributed compute clusters with the cheapest CPUs and GPUs across Hyperscalers and Neoclouds for AI. Our mission is to bring frontier-grade infrastructure to everyone. We're starting by building large scale high performance computing (HPC) clusters for quantitative trading firms to run parallel simulation workloads such as backtesting. Our technology generalizes to critical AI workloads such as post-training with reinforcement learning, fine-tuning, long-horizon agents with high tool use, and batch inference.

    This is pretty much the same thesis we had when we started Zibra Labs.

    This is pretty much the same thesis we had when we started Zibra Labs. A company that owns its intelligence digs and keeps it's moat.
