Waldemar is a serial entrepreneur, having started businesses together with Berlin-based incubators Rocket Internet and Team Europe. Together with Philip Siefer he founded the fairstainable condom brand einhorn in 2015. At some point in his career as a founder, growth, scale and money weren’t motivation enough: With the tools and skills he collected over the past years, he decided to use them for a better cause. Together with his co-founder Philip Siefer, he started Entrepreneurs Pledge, a movement that’s already gathered about 80 successful entrepreneurs to build a new kind of social companies – and make them grow, scale and with a significant revenue stream of which at least 50 percent must be re-invested in social or environmental cause. Fairstainability is part of their DNA. Einhorn is one of the first fairstainable businesses coming out of the Entrepreneurs Pledge initiative. Before founding einhorn together with Philip, Waldemar founded seven startups - and failed with all of them. Consequently failure is one of the topics of this entertaining and unconventional lectures.
