Resistant AI, a leading RegTech company specialising in AI-powered fraud and financial crime prevention, has raised $25m in a Series B.
The round was led by DTCP, with existing investors Experian, GV, and Notion Capital doubling down on their commitments. The company, which achieved breakeven in September, plans to use the new capital to strengthen its position as a profitable EU-based AI leader. This includes expanding its document fraud detection and transaction monitoring solutions into new markets and partnerships, while also enhancing its threat intelligence capabilities.
Resistant AI develops native AI models designed to identify fraud within documents, transactions, and behaviours. Its technology integrates with clients’ existing risk technology stacks, offering greater precision and contextual accuracy in detecting complex threats such as real-time payment (APP) fraud, synthetic identity schemes, money muling, generative AI-based document forgery, and sophisticated money laundering operations.
The company’s mission aligns with a growing demand for advanced solutions capable of countering AI-powered financial crime. Recent findings show that 35% of businesses have faced GenAI-related fraud, while Resistant AI’s Threat Intelligence division has tracked the growth of Fraud-as-a-Service markets offering over 160,000 pre-verified accounts from 3,000 financial institutions. With regulators around the world following the UK Payment Systems Regulator’s example in mandating APP fraud reimbursements, the need for intelligent fraud detection systems is more pressing than ever.
Since its Series A round, Resistant AI has seen its annual recurring revenue increase tenfold, with its customer base expanding fourfold. The company has verified more than 150 million documents and increased the number of transactions analysed for fraud and AML purposes by 100 times. Its client list includes Dun & Bradstreet, Payoneer, Close Brothers, PennyMac, AXA, Anna Money, Finom, and Bank of Valletta.
Resistant AI CEO and founder Martin Rehak said, “The financial crime landscape has fundamentally changed with the deployment of LLMs and AI agents in risk prevention settings, and the weaponization of generative AI by fraudsters. Our fraud and fincrime models offer any institution the tools to empower both their human and agentic co-pilots to combat these AI-powered threats at scale. This funding, combined with our near-term path to profitability, allows us to accelerate our mission of protecting the global financial system from increasingly sophisticated criminal networks.”
DTCP Growth partner Michael Rager said, “Resistant AI represents the future of financial crime prevention, with their in-house built multi-model approach to fraud detection marking a paradigm shift in how financial institutions can protect themselves and their customers. We look forward to partnering with Martin and the Resistant AI team to support the business in its next stage of growth.”
The company now employs over 100 staff across Prague, London, and New York, and continues to expand its reach within the global financial services and FinTech sectors.
