Help anti-fraud analysts and a neobank's customer service

What was done

On October 17, 2025, Le Monde Informatique reported on a Grand Théma trunging together AXA France, the Maif and Nickel. Thomas Courtois, President of Nickel (900 employees, including a third on technology), said that the neobank was very soon equipped with an up-to-date data base and a central data team linked to trades, and that it already has cases of GenAI being used in production. The most important, matching to Him, is the fight against fraud: generation of more relevant alerts and reduction of false positives, assistance to a hundred analytics to study these alerts, and identification of fraud networks. To ensure real results, Nickel tracks the length of a customer call and the resolution rate from the first call. It estimates the savings already made by its customer service with GenAI at EUR 1 million.Thomas Courtois also points out that, since agents are assisted on purely banking Nots, recruitment is directed more towards relational skills, including in catering or local commerce, than towards banking knowledge alone.
