Jonathan Hillebrand
I started experimenting with my first web projects at the age of 13. During high school I created and operated a homepage builder platform with 25.000 users and worked part time for SAP.
During my masters in business administration at the University of Hamburg, I had a peek into the exciting world of investment banking, with placements at Dresdner Kleinwort, Commerzbank and Goldman Sachs.
After experiencing regular 14 hour work days in Goldman's London office, I ultimately decided against it and never looked back. Now I can work from everywhere, have plenty of time for the important things in life and I do what I love.
