Bio

Marc has diverse experience across Product, Sales, Business Intelligence and full-stack engineering at companies from large (Google, DHL) to early stage startups. He graduated within the top 1% of his Masters in Management and Computer Science from Technical University Munich. Besides that, he loves to hack on personal project and connect with other builders (something he does not get to too much right now).
