Adam Niewinski is the Co-Founder and General Partner of OTB Ventures, a Warsaw-based deep-tech venture capital firm he launched in 2017 after spending 15 years at Bank Pekao and co-founding companies like Expander and Platinum Bank. His investment thesis targets Central and Eastern Europe with a sector focus on AI automation, SpaceTech, FinTech infrastructure, and Cybersecurity, positioning OTB as one of the top three European investors in SpaceTech. The firm typically invests between €1 million and €7 million per deal, preferring Series A as its “sweet spot” while acting as a leading or co-leading investor to secure 10–15% equity. Notable portfolio companies include Expander (which he founded and was acquired by GE Capital/Aviva), though specific OTB Ventures portfolio names beyond his own ventures are not explicitly listed in available sources. Niewinski has publicly emphasized that 2023 was a strong vintage year for VC and stresses investing only in game-changing, “outside of the box” tech ideas rather than marginal equity positions.
