004 seconds. That's how long UWflow takes to score an application.
How does your current process behave? That gap is adverse selection leaking into your P&L. UWflow closes it with Bayesian rigor, WOE precision, and constrained logistic models — every decision fully explainable to your regulator.
Every day your underwriting is manual,
you're paying for adverse selection.
The average European insurer loses €18–24M annually to mispriced risk in mortgage and personal lines. Manual scoring can't see the patterns. It can't adapt. It can't explain itself to the ECB.
Three Steps. Zero Black Box.
Every decision explainable. Every weight traceable. Regulators will thank you.
Transform
WOE binning converts raw features into monotonic, interpretable signals.
Chi-Merge and Decision Stump optimization. No arbitrary thresholds.
Score
Constrained logistic regression with Bayesian posterior estimation. Business constraints baked in. Coefficients you can defend to a committee.
Prove
Deterministic state-graph replay. Reproduce any decision at any point in time. Full audit trail. Your compliance team stops dreading model reviews.
Numbers, Not Adjectives
| Metric | Traditional UW | UWflow |
|---|---|---|
| Decision time | 4–72 hours | <10ms |
| Variables evaluated | 15–40 | 200+ |
| Adapts to market shifts | Quarterly (if lucky) | Continuous |
| Decision replayability | "Trust me, it's in a spreadsheet" | 100% deterministic |
| Regulatory explainability | Heuristic, black-box | Weight-level trace |
| Risk reduction (pilot) | — | 28–34% |
Scientific. Not Magical.
Built by actuaries who got tired of watching spreadsheets replace judgment.
Bayesian Posterior
Not just a score — a distribution. Every prediction carries calibrated uncertainty. Your committee sees the range, not just the point.
WOE + Optimal Binning
Chi-Merge and Decision Stump binning. Raw features become monotonic signals. No arbitrary cut-points. No "actuarial intuition" required.
Constrained LR
Logistic regression with business constraints. "Age must be positive" isn't a prompt — it's a hard constraint in the optimizer. Defensible by construction.
Ensemble Interaction Discovery
Boosting methods find feature interactions LR alone misses. "Age × LTV × region" — the three-way interactions that actually drive default.
State-Graph Replay
Every decision is a path through a state graph. Reproduce it. Challenge it. Prove it. Your auditor gets a timeline, not a shrug.
API-First Integration
REST, gRPC, or batch. Drops into your core banking, CRM, or decision engine. Your team's process doesn't change — the quality of the decision does.
90 Seconds. Real Logic. No Slides.
Watch the engine think. See every weight. Replay the decision.
Your portfolio is already priced
on the wrong model.
We'll run 500 applications from your book through UWflow. You get the score distribution, the factor contributions, and a one-page risk gap report. Free. No obligation. No sales call.
