Share

Prague-resident Resistant AI, the AI-driven financial crime and fraud detection pioneer, has secured $25 million in a Series B round led by DTCP Growth, with previous investors Notion Capital, Google Ventures (GV), and Experian doubling their bets. The firm, which broke even in September, intends to utilize the funding to scale up its document fraud detection and transaction monitoring solutions and launch threat intelligence services throughout Europe, making it a profitable EU AI market leader.

The funding arrives amid a surge in AI-driven financial crime, including GenAI-related fraud and sophisticated scams such as APP fraud, synthetic corporate identity fraud, and money laundering. Resistant AI’s proprietary machine learning models empower fraud, risk, and compliance teams, enhancing recall, precision, and contextual decision-making by integrating signals from existing risk technology stacks.

“Landscape of financial crime has been irreversibly altered by the use of LLMs and AI agents in risk prevention environments, and by the misuse by fraudsters of generative AI,” stated Martin Rehak, Founder and CEO of Resistant AI. “Our fraud and fincrime models provide any institution with the capability to enable both their agentic and human co-pilots in fighting these AI-facilitated threats at scale.”. This investment… enables us to speed up our mission of safeguarding the world’s financial system against more advanced criminal networks.

Since its Series A funding, Resistant AI has experienced 10x growth in ARR and 4x growth in customer base, proving more than 150 million documents and processing transactions at scale unmatched in the industry. Clients on its roster include Dun & Bradstreet, Payoneer, Close Brothers, AXA, and Bank of Valletta, with offices in Prague, London, and New York.

This new investment makes Resistant AI poised to capitalize on the growing need for AI-powered, multi-model fraud detection, protecting institutions from increasingly sophisticated, AI-driven financial threats.
