RL environments, benchmarks and expert data, built by practitioners.

The harness is not the hard part. The rubric is.
Expert RL environments, built to your domain and spec.
Each environment ships with the task, the tools, an expert-written rubric and a verifier. We build in corporate finance, GDPR and data protection, KYC and AML, employment, tax, medicines regulatory and cross-border corporate law.
EuroExec is the proof. Your held-out set is the product.
EuroExec is 598 tasks written by 44 practitioners and double-judged by 47 experts. Evaluate your model on the full held-out set, including unreleased checkpoints, and we'll send you the item-level failures. We never train on, or sell data derived from, the held-out set we score you against.
Send us 5 tasks. Get expert-graded data back in two weeks.
Send us 5 tasks, in the exact format you'd give your own team. We'll send back expert-graded data within two weeks. No cost, no commitment. You judge the output before anything else is scoped.

Six things we build and deliver.
Expert RL environments
Task, tools, expert rubric and verifier for agent training in regulated work, built to your domain and spec and tested before delivery.
Start a pilot →Private benchmarks and held-out evals
Private eval sets written and double-judged by practitioners, plus the EuroExec held-out set run on your checkpoints. You get item-level failures, kept apart from any training data.
Start a pilot →Preference data (RLHF)
Pairwise rankings and graded comparisons from professionals who know what "better" means in a credit memo, a DPIA or a board paper.
Start a pilot →SFT and reasoning traces
Instruction-response pairs and step-by-step reasoning written by practitioners against your spec, set in the jurisdiction the task belongs to.
Start a pilot →Red-teaming
Adversarial prompts from people who know what a wrong number in a financial model or a misread clause looks like, so your team can measure it and fix it.
Start a pilot →Rubric grading and long-form review
Practitioners grade reports, memos and filings against a rubric, yours or one we write. Two experts per item when you need agreement numbers.

Frequently Asked Questions
Yes. We deliver finished RL environments, benchmarks and datasets directly to labs. We fit as a second source for the European and regulated-work slice, next to the vendor you already run.
With a free pilot. Send us 5 tasks, in the exact format you'd give your own team. We'll send back expert-graded data within two weeks. No cost, no commitment.
Experts are checked against their credentials and tested in their domain before paid work. Every item is graded against a rubric, a share is double-judged with agreement reported, and a senior reviewer settles disagreements. On EuroExec, 76% of rubric scores land within ±1 point between the two experts. Experts work under our LLM-use policy.
Tasks are set in a named market and written by practitioners who work there, because the right answer in Frankfurt is not the right answer in Madrid. Experts work in English or the local language, across 23 European languages plus UK and US English.
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.
