## About this market
Financial-services buyers extending a team here are mostly buying the controlled path to production. Marionete's MLOps factory for AXA on Databricks and Azure DevOps carries a model registry, champion-challenger aliases, human approval controls and drift monitoring; its Beazley platform industrializes data products across underwriting and policy administration, and the payments orchestration platform tagged to HSBC is reported live in 54 countries at a 99.998% message success rate, data and integration engineering rather than models. Transparity's Bordereaux Sync validates bordereaux data to Lloyd's standards with a human review step. Ultra Tendency built the European Central Bank's statistical production platform and has run HUK-COBURG's telematics platform since 2016. In The Pocket put phishing detection inside KBC's mobile app, a model scoring uploaded screenshots. Vention's Kafene team grew from two to seven engineers on a lease-to-own platform with risk scoring, where the AI is coding assistants in delivery. Valletta's on-premises Qwen3-32B serving a DACH insurer 42,000 requests a day is a deep LLM case, and anonymous. Named LLM work sits with Version 1, whose policy-review system for broker Foundation Risk Partners runs in production with the client's COO reporting gap analysis cut from 40 hours to 4, and with DEUS, whose voice AI handles ABN AMRO's customer service calls autonomously. Stepwise's lending SaaS for Self Learning Solutions is live at four end clients with results reported as IT cost, not model outcome.

The sorting question in a regulated buyer's hands is who signs off a model release. Marionete's AXA work leaves approval gates behind; Ultra Tendency's Vattenfall case includes training so the client's teams operate the platform. Ask whether the embedded team builds your release controls or works inside ones you already own, and which named bank or insurer would confirm it.

## Questions buyers ask

### How many AI agencies work with team extension on fintech?
22 agencies in our directory combine verified team extension client evidence with documented FinTech work. The current top-ranked are Lexunit, Pixelette Technologies, Stepwise — 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 €20–130 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 the team extension model verified?
Every agency here documents team extension work on its own site or in a published case study, describing the engagement structure rather than a service-list claim. We never infer the model from portfolio tone, so this list only contains agencies that operate team extension engagements deliberately.
