About ThreatMark

Founded in 2015 by ethical hackers Michal Tresner and Kryštof Hilar, ThreatMark is a cybersecurity firm that provides fraud prevention solutions primarily for the financial services industry. The founders' journey began after Tresner's prior experience with a bitcoin currency exchange highlighted the critical need for robust identity verification to combat money laundering. This led to the creation of ThreatMark, which leverages their collective expertise in information security and cybercrime to address the shortcomings they observed in how financial institutions fought digital fraud.

The company operates on a B2B software model, serving banks, e-commerce platforms, and fintech companies. Its core offering is the Anti-Fraud Suite (AFS), a platform that integrates behavioral biometrics, transaction risk analysis, and threat detection. This system works by creating unique digital profiles for users based on patterns like keystrokes, mouse movements, and device interaction, allowing it to distinguish between legitimate customers and fraudsters in real-time. The platform analyzes data from devices, user sessions, and transactions to identify threats such as phishing, remote access attacks, account takeovers, and authorized push payment (APP) scams. In May 2025, the company launched ScamFlag, a new feature using Generative AI that allows bank customers to verify the legitimacy of potential scams by uploading screenshots within their banking app.

ThreatMark has shown significant growth, reporting a 75% year-over-year increase in annual recurring revenue over the last year. The Brno-based startup has secured a total of $37 million in funding over six rounds, with its latest Series A round in January 2025 raising $23 million. This capital is earmarked for market expansion into the UK and US, as well as for further research and development. Notable investors include Octopus Ventures, Riverside Acceleration Capital, and Springtide Ventures.
