Guardsquare

Founded by Eric Lafortune in Leuven, Guardsquare builds security software that protects mobile applications at the code level. Its products, including ProGuard (the widely used open-source Java bytecode shrinker and obfuscator) and DexGuard, are used by banks, healthcare companies, and consumer app developers to prevent their applications from being reverse engineered or cloned.

The company raised $29M to expand its enterprise go-to-market and product capabilities. Guardsquare is recognized as a technical leader in mobile app hardening and competes in a global market where mobile security is increasingly critical given the sensitivity of financial and healthcare data processed on devices.

Based in Leuven, Guardsquare benefits from proximity to KU Leuven's research output and the broader Flemish deep-tech ecosystem.
