The listed agencies clear that bar in public — Brainpool's case studies include market-abuse surveillance models for HSBC, Neurons Lab built an LLM content system for Visa and ran executive AI enablement for HSBC Vietnam, Faculty's published work includes generative-AI support automation for Tide, and Elsewhen has built for Mastercard and a licensed corporate neobank. The page has roughly trebled since: Datatonic built an AI banking assistant for the Swiss wealth manager Alpian and works with the insurer Hedvig, Satalia's published work includes reviewing $320 billion of investments for a hedge fund, Kortical publishes credit scoring and accounting automation, Mercury Labs builds for the capital-markets platform PrimaryBid, and Ekimetrics, Datasparq and Found bring financial-services delivery from modeling, optimization and demand sides respectively. Marionete works the layer underneath all of it—the data platform a bank's models run on, including a MiFID II compliance platform for a global broker and a self-service data science environment with AutoML for a global bank, with Saxo, HSBC and the Bank of England named on its site. For buyers, the roster question is regulated-delivery experience: ask how a candidate handled model documentation and sign-off in a supervised environment. An agency that has shipped under compliance review will answer specifically; one that hasn't will answer generally. ## Questions buyers ask ### How much do FinTech AI agencies in London charge?
