Proof
€2.1M losses prevented in year one
We worked with a retail bank.
The problem
The fraud team trusted its rules, but the rules were slow to change and impossible to explain to auditors when they fired.
What we built
Gradient-boosted models with a per-decision explanation, served in under 40 ms, and documentation written for model-risk review from the start.
The result
The model passed review on the first attempt and prevented €2.1 million in losses in its first year.
