About NobleStark
Proprietary data, custom benchmarks, and human-expert evaluations for any company building serious AI.
The data layer for serious AI
Modern AI systems are not bottlenecked by compute. They're bottlenecked by the quality, breadth, and credibility of the data they train on and the evaluations that measure them. NobleStark exists to be that data layer — built by senior practitioners, governed by clean contracts, and shipped with the kind of provenance procurement teams expect from a serious B2B vendor.
We build proprietary datasets, custom benchmarks, and human-expert evaluations for any company with serious AI data needs — from enterprise ML teams and applied-AI startups to the world's leading research labs and hyperscalers. We cover the verticals that matter most: code, math, reasoning, software engineering, and cybersecurity — with adjacent depth in RLHF, agentic trajectories, and safety/red-team evaluation.
The work is powered by Hatch, our vetted expert network of 5,000+ specialists across software engineering, cybersecurity, math, code, reasoning, and more. Senior engineers, researchers, PhDs, and competitive-programming and CTF veterans who earn top-of-market rates working on data that actually moves the needle.
What we build
Proprietary data
Custom datasets authored by domain experts, every item with provenance, rubric, and a verifiable test oracle wherever one exists.
Custom benchmarks
Bespoke leaderboards designed with your research team — spec, items, grader, and contamination-prevention protocol end to end.
Expert evaluations
PhD- and staff-engineer-grade evaluation services across code, math, reasoning, software engineering, and cybersecurity.
Hatch expert network
5,000+ vetted senior engineers, researchers, and domain specialists who get paid to do the work — not annotation farms.
Why we exist
NobleStark was started by engineers and researchers who watched, from inside the largest tech companies and AI labs, what happens when the data layer is treated as a commodity. Rubrics drift. Provenance disappears. Annotators race for piecework rates and the quality signal collapses into noise. Models inherit the worst of that noise.
We thought there was a better way: pay practicing experts what they're actually worth, build review pipelines that catch real mistakes, attach a provenance trail to every item, and treat the customer's rubric as the product. The companies you're competing with for the next leaderboard spot already operate this way internally — we make it available to everyone else building at the frontier.
How we operate
Quality is the product
Every item we ship has a name attached, a rubric attached, and a review trail attached. Procurement signs us off in days because the provenance story is already airtight.
Pay experts like experts
The best data is produced by the best people. We pay them top-of-market, contract them cleanly, and credit them in delivery — not race them against each other for piecework rates.
Stay frontier-aligned
New jailbreak classes, new model capabilities, new evaluation gaps — we refresh continuously so our customers ship into a world we already understand.
Be auditable
Per-item provenance, versioned rubrics, inter-rater reliability, contamination checks, held-out integrity. If a research lead can't reproduce the quality story, we don't ship it.
Built for procurement
We come ready with the documents serious procurement teams actually ask for:
