What predictive AI unlocks

The specific outcome depends on your business. But they all share one thing: data-driven decisions instead of guesses.

Better targeting

Predict who’s most likely to convert, buy, engage, or respond. Spend money on people who matter. Reduce waste.

Smarter operations

Optimize pricing, inventory, resource allocation, or any operational decision based on real data and predicted outcomes.

Proactive risk management

Identify customers at risk, deals likely to close, fraud patterns, or anything you need to act on before it happens.

From business question to live model

Phase 1: Discovery & Design

We run a workshop. What’s your actual business problem? What data do you have? What does success look like?

We tell you what’s possible, what’s hard, what’s worth doing. Sometimes the answer is “you need better data first” (data engineering), sometimes it’s a novel model.

Phase 2: Build & Validate

We build the model in your cloud environment. Training data, model selection, testing, validation. Your team learns alongside us.

Full transparency, code reviews, documentation. We don’t deploy anything you don’t understand.

Phase 3: Deploy & Integration

Model goes live. Integration with your ad platforms, CRM, dashboard, or any system that needs predictions. Training on monitoring and maintenance.

Your team now owns it. You can operate independently.

Phase 4: Your choice

We can step away completely. Or stay as ongoing partners for model monitoring, retraining, optimization.

Either way, you’re never locked in. Hire another team, extend the model, switch platforms. It’s all yours.

How we've delivered

Independer

Predictive conversion scoring for marketing efficiency

Marketplace with 3M+ users.
Highly competitive health insurance market.

The challenge

  • Media spend distributed evenly regardless of conversion potential
  • Retargeting included all users, not just high-potential ones
  • Bidding strategies disconnected from expected user value

The solution

Conversion probability model trained on 2 years of GA4 data. Scores every user session. Segments into low/medium/high conversion likelihood. Deployed in Google Ads and DV360.

YC

Predictive hiring optimization across channels

Recruitment platform. 20,000+ candidates placed weekly.
Largest young talent database in Europe.

The challenge

  • Unpredictable demand for vacancies across channels
  • No visibility into which channels drive lowest cost-per-hire
  • Existing tools optimized within platforms, not cross-channel

The solution

Predictive model on job openings, applications, GA4 data. Predicts job applications per week, retrains weekly. Tracks candidates from acquisition through contract signing.

Examples of models we've built

These are proven solutions we’ve deployed across industries.
But we build custom models for any business question. What you need matters more than what’s on this list.
