Frequently Asked Questions
Do you compete with RLHF and red-teaming data vendors?
No. We don't run our own RLHF, red-teaming, or annotation pipelines for AI labs. We supply the European domain-expert talent that you plug into your own pipelines, or that the data vendors you work with use to staff their projects.
What is the minimum engagement size?
We typically start with a 2-week pilot batch to establish alignment and quality benchmarks on your workflow before scaling the evaluator team. Minimum pilot is €5,000.
How do you ensure evaluator quality?
Every evaluator is verified through their university, screened on domain expertise, and onboarded against your rubric. Ongoing checks include cross-evaluation, gold-standard tasks, and PhD-level auditing of borderline cases.
Which languages do you cover?
All 23 official EU languages plus regionalised variants. Main non-EU coverage: UK English and US English.
Is your sourcing GDPR compliant?
Yes. Evaluator data and any task data we handle on your behalf stay inside EU-based AWS regions, with strict IP masking and EU data residency throughout.
Ready to staff your evaluation work?
No commitment. No sales pitch. Just a conversation.
