Moat
Aggregation of cheapest compute across hyperscalers; proprietary scheduling and utilization software.
Key risk
Hyperscalers building competing in-house solutions; razor-thin margins on commodity compute.
Why now
GPU scarcity forcing alternative hardware; reinforcement learning / post-training becoming bottleneck.

This company has previously operated under โ€œTBD. We don't have a name yet.โ€. A rename frequently marks a pivot in positioning or product โ€” useful raw material for variant ideas.

About

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 believe the bottleneck isn't just GPU availability, but effective utilization by the infrastructure software that runs on it. 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.

Former tech-lead of Ray. Previously building databases at LinkedIn. I've built systems that run on hundreds of thousands of machines and serve over a billion people.

Zac Policzer
Zac PoliczerFounder and CTO

After a career making software that serves over a billion people, with a background primarily in large databases, I'm now building HPC clusters at Zibra Labs The past two years I've been focused on what the next generation of AI data center software looks like โ€” and working to shape that future. I've been fortunate to do much of this in open source, which I'm deeply passionate about. Talk to me about databases, Mahjong, guitars, or weird horror movies. I'm currently building Zibra Labs.
