Eugene Claassen
Technical Director, SevenC
Eugene started his career in the trenches of IT support at Neotek in Empangeni, handling both business and residential clients.

Over time, he took on the responsibility of running the technical department, implementing critical processes like structured ticketing systems and customer monitoring. In 2016, EZNetworks merged with SevenC, where Eugene played a key role in restructuring the technical department to support rapid growth. His leadership helped shape SevenC into the thriving company it is today.
