Jiří is a second-time founder and CEO at Logmanager, on a mission to build another globally successful Czech cybersecurity company. His blueprint is Flowmon Networks — a university spin-off he helped grow from zero to a 140-person team with $15M in revenues and customers across 45 countries, before navigating its acquisition by Kemp Technologies and Progress Software.
At Flowmon, Jiří progressed from Technical Director through business development across Europe and Japan, before taking the helm as CEO for the company's final four years.

Prior to his commercial career, he was a researcher and project leader at CESNET, the Czech national research and education network, where he designed FPGA-based solutions for large-scale network monitoring and led participation in multiple European R&D projects — experience that gave him the deep technical foundation in network security, NetFlow/IPFIX, and FPGA technology that underpins his work to this day.

Beyond Logmanager, Jiří mentors founders and sits on startup and scaleup boards at JIC, committed to paying his success forward and helping the next generation of Czech technology companies reach global scale.
