EXPLORE OUR COMPANIES


Our investment team has more than 20 years of experience in founding, managing and investing in over 60 startups.

STS Ventures invests in start-ups in the DACH region. We are stage- and industry agnostic, but typically seek for pre-seed and seed-stage investments. We fill the gap between business angels and traditional venture capital firms. Sure, like most VCs, we welcome unicorn start-ups with hockey stick growth. But, we really love start-ups that achieve capital-efficient, sustainable growth. With Stephan, you will gain a partner with experience in building firms with a clear path to profitability.
