DTCP Growth leads the round as Resistant AI expands its fraud detection platform and threat intelligence to counter generative AI-driven attacks.
Resistant AI, the Prague-based provider of AI-native financial crime and fraud prevention technology, has raised $25 million in Series B funding led by DTCP Growth, with participation from existing backers GV (Google Ventures), Experian, and Notion Capital, who doubled down on their commitments.
The funding follows a period of rapid growth and near-term profitability for Resistant AI, which became breakeven in September. The company plans to expand its document fraud detection and transaction monitoring capabilities into new markets while advancing its threat intelligence and agent protection models.
“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,” said Martin Rehak, CEO and Founder of Resistant AI. “Our models empower both human and agentic co-pilots to combat these AI-powered threats at scale.”
Resistant AI’s technology uses proprietary machine learning to detect and prevent fraud in documents, transactions, and behaviors, integrating with existing compliance and risk systems. Its models deliver measurable uplifts in recall and precision while identifying complex schemes such as APP (Authorized Push Payment) fraud, synthetic identity creation, money muling, and AI-generated document forgery.
The company reports that since its Series A, its Annual Recurring Revenue (ARR) has grown 10x and its customer base 4x, processing over 150 million documents and increasing transaction monitoring volumes 100x. Its customers include Dun & Bradstreet, Payoneer, Close Brothers, AXA, Finom, PennyMac, and Bank of Valletta.
“Resistant AI represents the future of financial crime prevention,” said Michael Rager, Partner at DTCP Growth. “Their multi-model approach delivers a paradigm shift in how financial institutions can protect themselves and their customers.”
The funding comes amid a surge in AI-driven financial crime, with 35% of businesses reporting GenAI-related fraud in the past year. Resistant AI’s Threat Intelligence unit has uncovered a rapidly maturing Fraud-as-a-Service economy, where online marketplaces sell over 160,000 pre-verified accounts from 3,000+ financial institutions — fueling global APP scams costing economies more than $1 trillion.
Resistant AI currently employs 100+ team members across Prague, London, and New York, positioning itself as a profitable EU AI champion. Its suite — Resistant Documents and Resistant Transactions — integrates seamlessly with fintech and regtech stacks, enabling 3x greater document fraud prevention, 90% automation rates, and 5x faster review times.
