Czech Millionaire Ondřej Vlček Launches New Global Cybersecurity Venture Aisle

After stepping down as CEO of Avast and helping lead one of the Czech Republic’s biggest tech success stories, Ondřej Vlček is back with another ambitious project. His new startup, Aisle, aims to revolutionize how companies detect and fix software vulnerabilities with cutting-edge AI, world-class investors, and a strong Czech footprint.

Ondřej Vlček, one of the driving forces behind Avast’s global expansion, has unveiled his new cybersecurity company Aisle. The Prague-based startup already employs around 40 experts spread across the USA, Israel, the Netherlands, and Poland. Vlček’s goal is to address one of the toughest problems in cybersecurity, the slow process of detecting and resolving vulnerabilities in corporate systems.


Aisle’s product, developed in secrecy for nearly a year, leverages artificial intelligence to continuously map an organization’s software environment. The result promises to reduce patching time from weeks or months to mere hours or even minutes, giving companies the ability to neutralize threats almost in real time.


The founding team brings together leading cybersecurity and AI specialists with backgrounds in major global technology firms and research institutions. Their expertise bridges practical enterprise security with the newest developments in machine learning. Aisle has also attracted several high-profile angel investors from the global tech scene, underlining the trust and anticipation surrounding this new Czech-born venture. Among Aisle’s first design partners - companies that test and refine the platform, are several Czech-origin global players demonstrating the growing synergy between Czech innovation and international cybersecurity demand.


Vlček summarized Aisle’s mission clearly: to give security professionals hope that a fully cleared backlog of vulnerabilities doesn’t have to be science fiction. With its unique blend of AI precision and Czech technological talent, Aisle is poised to become the next major Czech-born cybersecurity success story.
