10 AI Startups Fighting Fraud Before It Strikes

Jan de Vries · 2026-06-09

Fraud prevention is quickly becoming a cornerstone of Europe's cybersecurity and FinTech scene. Organizations are facing a growing wave of threats: scams, identity theft, account takeovers, and AI-powered financial crime. The stakes are higher than ever. As attacks get more sophisticated, startups across the continent are building AI-driven tools to spot suspicious behavior faster, strengthen digital identity checks, and cut down on financial losses. The need is especially clear during peak travel seasons. According to Stoïk, seven out of ten companies face cybersecurity threats in the summer, with the tourism sector accounting for 70% of those incidents. That's a wake-up call for any business handling lots of customer data and online transactions. In EU-Startups' 2026 coverage, cybersecurity-focused fraud detection is zeroing in on human-targeted attacks like impersonation and credential theft. Take Spain's Zepo Intelligence and France's MokN — together, they raised about $27.8 million in 2026 (converted from €25.7 million at an approximate rate of 1 EUR = 1.08 USD). That kind of funding tells you investors are betting on tools that catch fraud early, before attackers can access accounts, move money, or steal sensitive data. Here are 10 promising European startups building tech to help organizations identify, prevent, and respond to fraud. ### Acoru: Stopping Fraud Before Money Moves Madrid-based Acoru created a system that helps banks and financial companies spot fraud before money changes hands. Its AI platform looks at account behavior, login activity, transaction patterns, and other risk signals to catch suspicious activity tied to scams, fake accounts, money mules, and financial crime. The system ranks accounts by risk level, so banks can decide whether to block, review, or just monitor activity before a transaction goes through. It also lets organizations share fraud signals with each other while keeping customer data private. Founded in 2023, Acoru raised $15.1 million in total funding (converted from €14 million). ### AVIEL Intelligence: Stopping Payments to Scammers Launched in 2024, AVIEL Intelligence helps financial institutions prevent customers from sending money to scammers. It monitors digital interactions to spot signs of financial grooming, scam activity, and risky payment behavior before fraudulent transactions go through. AVIEL works with banks, payment providers, regulators, and other organizations looking to strengthen digital security. It offers its tech through a subscription model and partnerships. Based in London, the startup secured $750,000 in funding (converted from €695k). ### FALKIN: Early Intervention for Banks FALKIN, based in London and founded in 2024, builds AI tools that help banks protect customers from scams before payments happen. Its tech analyzes behavioral and digital risk signals to detect signs of deception early. It can be embedded into banking apps, customer-service portals, and other trusted digital channels. The platform lets financial institutions step in earlier when a customer shows signs of scam risk. FALKIN has raised $1.8 million in total funding (converted from €1.7 million). ### MokN: Tricking Attackers with Decoys Paris-based MokN is a cybersecurity startup that protects organizations against credential theft. Its platform uses realistic decoy access points — like fake VPN or webmail portals — to trick attackers into entering stolen credentials before they can be used or sold on the dark web. This gives security teams a head start in detecting and responding to phishing attacks. MokN works with large companies and mid-sized organizations, and it says it protects more than 1 million users. Launched in 2024, its total funding is $16.7 million (converted from €15.5 million). ### Prelude: Verifying Users with Data Signals Headquartered in Paris, Prelude uses telecom data, device intelligence, network signals, and behavioral patterns to assess whether a user is legitimate — both during onboarding and later interactions. Its tools include APIs that help businesses verify identities without relying solely on passwords. Prelude's approach is all about layering different signals to create a more complete picture of user trustworthiness. That makes it harder for fraudsters to slip through. ### Why This Matters Now These startups are tackling fraud at its roots — before it causes real damage. And the numbers back it up. With $27.8 million flowing into just two companies in 2026, it's clear the market is hungry for proactive solutions. Whether it's through AI, decoys, or behavioral analysis, the goal is the same: stop scammers before they strike. If you're in the US and watching European innovation, these startups are worth keeping an eye on. They're proving that the best defense is a good offense.
