A passion for innovation and its shaping in different cultures accompanied Jannes since his early childhood; being born in Tunisia, the son of a Swiss scientist working on an innovative development project for the French Sorbonne University and a Slovenian psychologist and lawyer, who fostered his interest in analytics and the context of things at an early age.  Jannes spent most of his early educational years in Zurich and Basel, where he graduated from the University of Basel with a focus in business law and economics. In his early career he worked for banks and corporate law firms, where he developed legal methodologies for the implementation of innovative technologies and investment solutions.

During the spread of the personal computer and the internet, he became involved in venture capital transactions while working for a large New York law firm. Since that time, Jannes has advised and accompanied countless start-ups, from financing to formation to further development. He has advised on numerous mergers and acquisitions transactions and restructurings, including the sale of a Swiss technology start-up in one of Google's first acquisitions in Europe. He has also advised on the legal framework of technology companies and overseen the transformation from static sales concepts to innovative service offerings, such as the introduction of software as a service (SaaS) and cloud computing. Jannes is also a founding partner of the law firm Schoch Jaeggi Hoch in Zurich.
