## About this market
Financial services is the thread running through the Paris roster. Wavestone's published AI work includes generative document processing for the Helvetia Group and AI use-case prioritization in wealth and asset management, sitting beside a practice built on DORA, NIS2 and the EU AI Act. Artefact's agentic deployment at Bpifrance put AI agents in front of 500 employees at a public investment bank. AI Sisters works with private-equity and investment firms on AI enablement, and Mozza's client list runs through the French fintech generation—Qonto, Payfit, Alan. Serokell arrives from the engineering side, with a financial-platform record that runs back through Cardano and StakerDAO alongside its machine-learning practice.

French supervision adds a documentation layer that the AI Act sharpens further, since creditworthiness scoring sits in its high-risk tier. Ask how a candidate documented a model for the audit, and who held the human-oversight role. Firms that have shipped under review answer with the artifacts; firms that have not answer with the architecture.
