Rupprecht Rittweger, a highly successful serial entrepreneur, held a guest lecture on his eventful entrepreneurial career. While still a student in the field of Economics, Rupprecht founded a textile business. Later on, he seized opportunities in the real estate industry and founded e-shelter GmbH & Co. KG in 2000. He is managing director at e-shelter and partner at Investa Holding GmbH. Rupprecht puts a strong emphasis on the role of founding partners and social networks and we are very happy to have him come back to Mannheim to share his experiences.
