What Zibra Labs does

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.

Distributed Compute for AI

What is your company going to make? Please describe your product and what it does or will do.

We build distributed compute clusters that combine the cheapest CPUs and GPUs across major public clouds and smaller providers. Our first product targets quantitative trading firms running large-scale parallel simulations like backtesting. The architecture also supports heavy AI workloads like reinforcement learning post-training, fine-tuning, and batch inference.

Where do you live now, and where would the company be based after YC?

We live in San Francisco, CA, and the company will be based here after YC.

Explain your decision regarding location.

San Francisco is a hub for both AI and finance tech, which fits our focus on HPC for quantitative trading and AI workloads. Proximity to potential customers and investors matters.
