## About this market
Financial services is Europe's most experienced AI buyer, and the B2B-verified agencies here have documented work inside its operational core. Brainpool's case studies include market-abuse surveillance models for HSBC. Faculty's support tooling runs inside the business bank Tide with a published handle-time reduction. Neurons Lab builds specifically for regulated financial environments—Visa's LLM content system shipped with stack and timeline published—and Amsterdam Data Collective's transaction-monitoring work sits squarely in the compliance engine room. Sputnik Digital's Invntry engagement brings the insurance side: image identification that itemizes and values belongings from photos.

B2B fintech work faces two masters—the operational owner and the supervisor—and the useful screen is which of the two a candidate has satisfied before. Ask how documented models were reviewed, who held oversight, and what the audit trail looked like. The EU AI Act tightens this further for credit and risk systems. Firms on this page have shipped under that scrutiny; their premium over generalist engineering is the cost of not learning it on your budget.

## Questions buyers ask

### How many AI agencies work with B2B on fintech?
69 agencies in our directory combine verified B2B client evidence with documented FinTech work. The current top-ranked are Storm Technology, AI Sisters, Lexunit — 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 €45–175 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 B2B experience verified on this page?
Each listed agency has at least two documented, named B2B 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?
3 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.
