Verified European experts. AI training data in 48 hours.
PhDs and graduate students from 50+ top European universities, pre-vetted and ready to label. RLHF, evaluation, domain reasoning. GDPR-native, EU-hosted, vendor-neutral.
The status quo
Frontier models need expert humans. Sourcing them is broken.
Generic crowds, expert problems
Crowd labelers can't evaluate PhD-level reasoning. Reinforcement learning on frontier capabilities needs annotators who can spot the flaw in a proof, the missed differential in a clinical note, or the bad analogy in a legal brief — not workers paid by the click.
US vendors, EU obligations
US-based vendors weren't built for the EU AI Act, GDPR, or European data residency. Their DPAs don't survive a serious legal review, their SCCs paper over what should be a real architectural answer, and their data leaves the continent the moment a task starts.
Six weeks for six hours of work
Enterprise sales cycles take six weeks for what should take six hours. A research team that needs 500 annotated samples this sprint should not be filling out vendor onboarding forms next quarter.
How it works
From brief to delivered data in five stages.
- 01
Brief
Domain, volume, budget, deadline.
- 02
Auto-match
Skills × availability × rate.
- 03
Quality gate
Gold-question screening and sample approval.
- 04
Live annotation
In your tools or ours, with IAA and anomaly detection.
- 05
Delivery
API or export. Full audit trail. Direct payout to experts.
Why us
Built for European AI labs, by people who’ve shipped them.
European supply
Direct university partnerships, not LinkedIn scraping. We work with department heads and graduate programs to identify expert pools at source, then verify credentials before anyone takes a task.
Vendor neutral
Independent, with no AI-lab ownership stakes. We don't train competing models on your data, we don't own a stake in the labs we serve, and we don't pick favorites in your evaluation pipelines.
Bring your own tooling
Plug experts into Label Studio, Argilla, or your custom stack. Data never leaves your infrastructure — we route identity, payout, and quality, you keep the annotations on your servers.
Transparent pricing
Fifteen percent flat platform fee. Experts see exactly what they earn, you see exactly what we take. No spread, no hidden margin, no opaque enterprise quote.
Use cases
What teams build with Expert Lab.
RLHF preference data
Pairwise comparison, ranking, and rationale capture at PhD depth.
Model evaluation
Benchmarking, regression testing, and capability-gap discovery.
Domain reasoning
Math, law, medicine, finance — generated by people who teach it.
Multilingual evaluation
25+ European languages, native-speaker reviewers, dialect coverage.
Red-teaming and safety
Adversarial prompts and safety classifications from cleared experts.
Custom expert panels
Standing panels for ongoing eval or one-off briefs in niche fields.
Compliance & security
Built for European AI.
We treat compliance as architecture, not a checkbox. Every artifact below is documented and reviewable under NDA.
