## About this market
Fintech startups buy AI under two pressures at once: a regulator who will eventually ask how a decision was made, and a runway that will not fund a research program. The documented work here splits along that line. Buildo built Banksealer's on-premises ML fraud-detection product with Secure Network on Politecnico di Milano research, in Scala and Kafka—a deployed product rather than a pilot. xtream works the forecasting and planning seam, launching Credimi Assist, a B2B cashflow-management SaaS, in six weeks. 010 Coding Collective's CV-screening system comes with a full compliance write-up: explainable scores, no training on historical data, an audit trail the client's legal team accepted, and an external audit passed. Modulai brings a production machine-learning bench with its model choices stated, including a Bayesian hierarchical logistic regression built for small-business credit risk—a stated model choice in a market that mostly writes "AI-powered".

The screen that matters at this scale is explainability, and it is cheaper to buy than to retrofit. Ask each candidate for a system where a decision had to be justified to someone outside the engineering team, and what artifact they produced to do it. Credit and risk models sit in the EU AI Act's high-risk tier, so a startup shipping a black box now is buying a rebuild later, and the firms here that have already produced audit trails will say so without prompting.

## Questions buyers ask

### How many AI agencies work with startup on fintech?
15 agencies in our directory combine verified startup client evidence with documented FinTech work. The current top-ranked are Pixelette Technologies, Modulai, OstraconAI — ordered by depth of documented client evidence, then our editorial scoring (portfolio quality, credibility, completeness); placement is never paid.

### How much does an AI agency cost for fintech?
Published rates across this page's agencies run €20–300 per hour (median ~€65). Project totals depend on scope — the rate index at /rates breaks the computed bands down by region, country and team size.

### How is startup experience verified on this page?
Each listed agency has at least two documented, named startup clients — published case studies or engagement descriptions our research actually read, with source URLs stored per client. Logo walls without published evidence carry no weight, which is what separates this list from self-declared directories.

### Can these agencies embed consultants with our team?
6 of the agencies on this page document an embedded / team-extension working model. See the team-extension page for the full verified list, or check the engagement chips on individual profiles.
