HPC for Quant Trading Firms running backtesting at scale.

Spring 2026ActiveB2BInfrastructureArtificial IntelligenceFintechCloud ComputingInfrastructureSan Francisco, CA, USA
Quant research is generating candidate strategies orders of magnitude faster than backtesting infrastructure can evaluate them. AI has further accelerated alpha research from a handful of signals per quarter to hundreds per day. The bottleneck has moved from researcher time to compute throughput. We're building large HPC clusters (100 - 50,000 nodes) that can run up to 6.4M tasks in parallel across multiple cloud providers on spot instances. Our goal is to make backtesting strategies simple, fast, and cheap at scale.

Note: This is a preliminary assessment based on limited publicly available information. We did not have access to LinkedIn profiles or live product screenshots for this analysis. We will update this entry with a more thorough review soon.

Verdict

High Signal
Market Opportunity
Quant trading firms (hedge funds, prop trading shops) have enormous compute budgets and a very clear, acute pain point: backtesting throughput bottleneck as AI accelerates strategy generation. B2B infrastructure with a well-defined ICP (quant research teams at mid-to-large firms). Pricing power is high — firms will pay for edge that translates to alpha.
Medium Signal
Founder Signal
Ibrahim Rabbani claims to be a former tech lead of Ray (the distributed computing framework from Anyscale/Berkeley), which is a highly relevant and impressive credential for building HPC infra. Zac Policzer claims large-scale database work serving over a billion people and two years on next-gen AI data center software in open source. However, LinkedIn profiles are unavailable so none of these claims can be independently verified — this is a significant gap. If the Ray claim is accurate, that's genuinely strong signal for this specific problem.
Medium Signal
Competition
No competitor data returned, but the space includes AWS/GCP/Azure HPC offerings, Coiled (Dask-as-a-service), Modal, and internal builds at large quant firms (Two Sigma, DE Shaw, etc.). The differentiation claim is quant-specific optimization at 6.4M parallel tasks with spot instance orchestration across clouds — plausible moat if they can execute, but big cloud providers and general HPC players like Rescale are real threats.
Low Signal
Product
No live demo, no pricing page, no customer logos, no API docs, no revenue or usage metrics visible. Website is essentially a landing page with a concept description. Pure vaporware stage — no evidence of a working product or paying customers.
OverallB Tier

The market thesis is solid — quant firms genuinely are bottlenecked on backtesting compute as AI floods the strategy pipeline — and if the Ray tech-lead credential checks out, this is a technically credible team for the problem. However, LinkedIn profiles are unavailable which prevents verification of the core founder claims, and there is zero visible product traction, no press, no customers, and no proof of a working system. The idea is compelling and the ICP is crisp, but this is entirely pre-traction with unverified credentials, which keeps it firmly in B territory. Needs to show a live cluster, a pilot customer, or at minimum open-source tooling to move up.

Ibrahim Rabbani
Founder and CEO

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 Policzer
Founder 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 — 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.
