Applied AI from Lahti, Finland · since 2018
We build AI that has to earn its place.
Oppi AI turns peer-reviewed research into products that work in real use. Our first product is WorkProbe: it turns a job description into a 45-minute work trial and gives you a ranked shortlist.
Hiring?
Send candidates one link. Get a ranked shortlist before the first interview. Your first role is free.
Investor or partner?
Oppi AI is pre-seed. WorkProbe completed its first paid pilot in September 2026. We are talking to investors and hiring partners now.
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.
WorkProbe: a real work trial before the interview
CVs and take-home tests are now often written by AI. WorkProbe shows how a candidate actually works. Each candidate gets a 45-minute simulated task with documents, simulated colleagues and an AI assistant, just like a real job. AI is part of the workplace, not the thing being tested.
- Role skills
- AI collaboration
- Critical verification
- Judgment under uncertainty
Each skill is graded Strong, Acceptable, Weak or Poor. No numeric scores.
Grounded in peer-reviewed research from MIT, Harvard and Nature Human Behaviour.
