About provantis IT Solutions

For many years, the computer scientists Thilo Jahke and Oliver Lieven accompanied medium-sized and large companies as consultants and project managers. In 2000, they founded provantis IT Solutions with the aim of realising a solution for recording working hours on projects in modern web technology and became one of the pioneers in the field of software-as-a-service with the development start of ZEP. Since then, ZEP has been continuously developed further based on customer requests and today provides a central software in everyday life for more than 1,500 corporate customers with more than 40,000 users. With the change of generations in the management, provantis will continue to exist as an owner-managed company through Benny Hahn and Christian Bopp for a long time to come and will continue to develop ZEP close to customer requirements in the future.
