Quant Labs

Technical rigor. Financial rigor.
One decision.

We independently test the technology behind AI, robotics, and quantum computing companies before making an investment decision. Quant Labs is a technical and financial due-diligence engine — we underwrite the business fundamentals alongside the technology, then bring vetted opportunities to our investor network, whether or not we invest ourselves.

Recent Evaluation

We're already doing the work

Before we ever evaluate a portfolio-stage company, here's the same Claim → Evidence → Test → Result framework applied to a public, independently-checkable technical claim.

Technical Evaluation #001

Verifying vLLM's PagedAttention Throughput Claims

Claim
vLLM's PagedAttention memory management delivers substantially higher LLM-serving throughput than baseline alternatives.
Result
The core mechanism checks out against the peer-reviewed paper and vLLM's own published benchmarks — with the caveat that the technology has moved since the original claim.
Remaining Risk
This is a desk-based verification of public evidence, not a hands-on lab benchmark we ran ourselves — the standard we hold actual portfolio-stage companies to is higher.

Technical Evaluation #001: vLLM PagedAttention — Validation of Throughput and Memory-Efficiency Claims

The first in a new series: a desk-based, fully-sourced verification of vLLM's PagedAttention throughput claims against the peer-reviewed paper and vLLM's own published benchmarks — what holds up, what we can't confirm without hands-on access.

The Financial Side of Our Diligence: What We Actually Underwrite

Technical evaluation gets the attention, but every opportunity we evaluate is also underwritten financially — here's what we actually look at.

Why We Bring Vetted Deals to Our Investor Network

Our core value isn't being the capital source — it's being the due-diligence engine that de-risks deals for the investors we work with.
