Resistant AI provides machine-learning models that spot fraud in documents, transactions, and customer behaviour, integrating with a client’s existing risk tech stack. Its flagship products, Resistant Documents and Resistant Transactions, claim to deliver a 3× increase in document-fraud prevention, 5× faster review times, 90% automation rates, and a 5× boost in analyst productivity. The company reports that since its Series A round its annual recurring revenue has grown 10-fold, its customer base has quadrupled, and it has verified more than 150 million documents while increasing the number of transactions analysed for fraud and AML 100×. Customers include Dun & Bradstreet, Payoneer, Close Brothers, PennyMac, AXA, Anna Money, Finom, and Bank of Valletta. Resistant AI reached breakeven in September and now employs over 100 people across offices in Prague, London, and New York. With the new capital it plans to broaden its document-fraud and transaction-monitoring offerings to new territories and partners and to build out threat-intelligence capabilities in Europe. Management positions the business as a profitable EU AI champion protecting both human and autonomous “agent” fraud-fighters against increasingly AI-driven criminal networks.
