STS Ventures GmbH
Stephan Schubert established STS Ventures after founding and selling companies such as OnVista, Ligatus and IS.Teledata. The firm operates as his single-family office vehicle while functioning as an early-stage investor. Wealth origin traces directly to those exits in German online services. STS Ventures targets pre-seed and seed rounds in the DACH region. It commits €200k–€1m initially and follows on to a €5m maximum per company. Asset classes include enterprise software, digital health, climate technology and fintech. Confirmed positions include JustWatch, ottonova, Emma – The Sleep Company, Baqend and Klima.metrix. The firm also holds real-estate assets through STS Real Estate GmbH in Cologne. Geographic focus remains Germany, Austria and Switzerland. The team comprises six professionals in Cologne. Stephan Schubert serves as Managing Partner alongside Partner Oliver Kaul and four additional investment and operations staff. No additional offices are disclosed. Stephan Schubert Stiftung operates as the associated philanthropic vehicle. No operational events from the last 24 months appear in public records. The structure combines family-office capital with venture deployment. Schubert participates directly on boards and supplies founder-level feedback rather than delegating to external managers. This model produces co-investment opportunities alongside other angels and early VCs while maintaining full discretion over follow-on decisions.
