20 years of network technology,
seen through the lens of a European vendor.

Born in East Germany in 1986, my passion for telecom technology inspired me to found AirZen, a global company empowering businesses to control their WiFi and network solutions in today’s CyberSecurity landscape.


AirZen’s technology now powers 10,000+ locations worldwide, backed by a dedicated team across continents. With 20+ years in tech, I’ve built a portfolio of innovative brands delivering tailored network solutions for unique markets.


Precision, innovation, and impact—German engineering at its finest.


Let’s shape the networks of tomorrow, today.
