Resistant AI, a leading provider of native AI models for financial crime and fraud prevention, announced a $25 million Series B funding round. The round was led by DTCP, with continued support from Experian, GV, and Notion Capital. Following breakeven in September, the new capital will strengthen Resistant AI’s position as a profitable EU AI leader, expanding document fraud detection, transaction monitoring, and threat intelligence capabilities.
The anti-fraud and regtech market is evolving rapidly, with agentic AI solutions replacing static workflows. Large language model-based agents, however, remain limited in quantitative risk analysis, prone to hallucinations, and challenging to secure.
Resistant AI’s machine learning models detect fraud in documents, transactions, and behaviors, leveraging signals from the broader risk stack. This approach improves recall, precision, and contextual decision-making for threats such as real-time payment (APP) fraud, synthetic corporate identity fraud, money mulling, generative AI document fraud, and complex money laundering schemes.
Financial crime is accelerating under AI influence, with 35% of businesses reporting GenAI-related fraud. Threat Intelligence research shows the Fraud-as-a-Service economy now sells over 160,000 pre-verified accounts from 3,000+ financial institutions to fuel APP scams, costing trillions globally. With regulators following the UK’s mandatory APP reimbursement rules, advanced detection solutions are critical.
Since Series A, Resistant AI’s ARR increased 10x, while the customer base grew 4x. The platform leads AI-driven document fraud detection, verifying over 150 million documents, and analyzing fraud and AML transactions 100x more than before.
Martin Rehak, CEO and Founder of Resistant AI, 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."
Michael Rager, Partner at DTCP Growth, commented: "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."
Resistant AI protects global financial institutions, fintechs, and enterprises, including Dun & Bradstreet, Payoneer, Close Brothers, PennyMac, AXA, Anna Money, Finom, and Bank of Valletta. The company employs 100+ team members across Prague, London, and New York.
