Applied AI from Helsinki · since 2018
We build AI that has to earn its place.
Oppi AI is a Helsinki applied-AI company. We turn peer-reviewed research into products that hold up under real conditions — starting with WorkProbe, the hiring assessment for the AI era.
What we believe
We started in 2018, before the hype. Our view hasn't changed: AI is a tool that has to earn its place — measured against real conditions, not demos.
Research-grounded
We build from peer-reviewed evidence, not vendor claims. If the research doesn't support it, we don't ship it.
Built for production
Systems designed around a specific business problem, built to work when it's live — not just when it's pitched.
Judgment-first
We care whether AI actually improves a decision, not whether it looks impressive doing it.
We track how AI is changing work, decision-making, and team performance, and translate that research into practice.
Our first product
WorkProbe
Top 100 Innovations · ARCTIC15 2026WorkProbe measures judgment under ambiguity — whether a candidate's independent reasoning holds up when an AI assistant gives a confident, wrong answer. It's the one thing most hiring processes don't test for in the AI era. Grounded in peer-reviewed research from MIT, Harvard, and Nature Human Behaviour.
Stop testing knowledge. Start testing judgment.
