• This latest investment brings the company’s total funding to more than $55 million, aimed at expanding its AI-powered fraud and financial crime prevention solutions.
• The major raise puts a spotlight on the Czech Republic’s booming tech scene, positioning Prague as a critical hub in Europe’s cybersecurity ecosystem.
• Resistant AI focuses on tackling the rise of AI-generated financial threats, including sophisticated document forgery, synthetic identities, and money laundering schemes.

Prague’s Fintech Innovation Scene Gains Global Traction

In a move that sends ripples through the European tech community, Prague’s own Resistant AI has closed a $25 million Series B funding round. The investment, led by DTCP Growth with continued support from heavyweights like Google Ventures and Experian, isn’t just a win for the company. It’s a signal that Prague is becoming a serious contender in the global fight against financial crime. According to reports from EU-Startups, this funding positions the Czech firm to scale its advanced security solutions significantly.

Michael Rager, a Partner at DTCP Growth, called the investment a “paradigm shift in how financial institutions can protect themselves and their customers.” This funding underscores the growing importance of Czechia as a powerhouse for fintech security innovation, proving that groundbreaking tech isn’t limited to Silicon Valley or London.

$25 Million to Expand Fraud Detection and Intelligence

With this new capital, Resistant AI’s total funding now tops $55 million. The company isn’t just stockpiling cash, though. CEO Martin Rehak explained, “This investment allows us to scale our AI-driven defense systems and stay ahead as financial threats evolve.” It’s a proactive move, especially since the company already hit profitability in September 2025, giving it a solid foundation before taking on more funding.

The primary goal is to push into new markets and build stronger partnerships. A big piece of that puzzle involves beefing up their threat intelligence and analytics tools to give clients an even clearer picture of the risks they face. As detailed by The SaaS News, the funds are earmarked for expanding its document fraud and transaction monitoring solutions.

Tackling Real-World Fintech Fraud with Advanced AI

Resistant AI is on the front lines, battling some of the trickiest fraud vectors out there. Its core products, Resistant Documents and Resistant Transactions, are designed to sniff out forged documents, synthetic identities, money laundering, and authorized push payment (APP) fraud. These aren’t just theoretical threats, they are everyday problems for a client roster that includes big names like Dun & Bradstreet, Payoneer, AXA, and PennyMac.

The results seem to speak for themselves. According to the company’s internal reviews, their AI models have led to a 3x increase in fraud detection and a 5x faster review time for their clients. Even more impressive is a reported 90% automation rate, a figure that showcases the power of applying AI to complex security workflows. This level of efficiency mirrors a broader trend in business, where companies are adopting platforms like Make.com to automate processes and stay competitive.

Michael Rager of DTCP added, “Resistant AI’s multi-model approach is the most advanced we’ve seen, creating tangible impact for banks and fintechs.” This is the kind of practical application that is reshaping how businesses approach their finances, much like the rise of AI-powered CFO tech.

The Growing Challenge of AI-driven Crime

The need for these tools has never been greater. Criminals are getting smarter, and they’re using the same AI technology to their advantage. “Old methods can’t keep up—criminals are now exploiting generative AI to manufacture documents and fake identities at industrial scale,” warned CEO Martin Rehak. It’s a digital arms race where fraudsters are leveraging increasingly sophisticated tools, including deepfake scams and AI impersonators to bypass traditional security checks.

The numbers are stark. A recent survey revealed that a staggering 17% of all documents used in know-your-customer (KYC) and lending processes worldwide are either altered or outright fakes. Rager also pointed out that large language models, the tech behind many generative AI tools, can “hallucinate” or invent information 10-30% of the time, making native AI security essential for anyone who needs to stay compliant.

Recommended Tech

As fraudsters get better at faking identities online, protecting your personal information is more important than ever. While Resistant AI secures businesses, individuals need their own line of defense. The TechBull recommends Aura for its all-in-one identity theft and online threat protection, helping you stay a step ahead of digital criminals.

Prague Emerges as Europe’s Fintech Security Nerve Center

With a team of over 100 experts spread across Prague, London, and New York, Resistant AI has a global footprint, but its heart is clearly in the Czech capital. “Prague is now on the map as a central node in Europe’s AI and fintech security ecosystem,” Rehak stated proudly.

This success isn’t happening in a vacuum. Other Czech fintech and security firms are also gaining momentum, drawing more investment and talent to the region. This investment, which SecurityWeek notes is one of the largest for a Czech startup in this space, helps solidify the city’s reputation as a growing tech hub.

What’s Next for Resistant AI

Looking ahead, Resistant AI plans to use the funds to double down on research into new AI-driven fraud techniques while making its transaction monitoring tools easier to integrate for a wider range of customers. The goal is to stay nimble and adaptive in a world where cyber threats are constantly changing.

“Our mission is to empower every fintech to stay one step ahead, no matter how rapidly the threat environment shifts,” Rehak said. It’s a bold vision, but one that investors are clearly buying into.

Rager summed it up best. “We expect to see Resistant AI define best practices in the next generation of fintech security, not just in Europe, but globally.”
