## About this market
London's financial concentration is visible in this roster and largely absent from its published outcomes, which is the pattern a fintech buyer should expect. Neurons Lab is the only firm here built for the sector: its Visa case study publishes architecture diagrams, the SageMaker and LangChain stack and compliance design under PCI DSS and GDPR, and its enablement programs name HSBC Vietnam, PrivatBank and Oschadbank—but the strongest platform work, an agentic system for a capital-markets fintech with sub-30-second alert times, is anonymized. Brainpool's HSBC engagement confirms bank-grade work exists, and its published write-up stops at the challenge with no outcome stated. Elsewhen names Mastercard and Zego among its clients while its AI cases name a sector and stop. Behind them sit the infrastructure builders: Marionete builds enterprise data platforms for banks and brokers, Satalia runs decision systems for financial clients, Kortical does document automation and forecasting, and Datatonic and Ekimetrics bring the data and modeling layer.

So the recurring shape is a marquee client name on one page and an AI outcome on another, rarely joined. Ask which of those two lists your reference call would come from—that question sorts this roster faster than any capability comparison. Beyond it, regulated buying turns on artifacts rather than architecture: model documentation, monitoring records, the human-oversight arrangement, and a written account of what the system does when it is unsure. Anyone who has shipped inside a bank produces those without delay. Published bands run €20-175 an hour, and the cheap end is engineering capacity rather than compliance experience.
