OTB Ventures
Pan-European deep-tech VC (Amsterdam/Warsaw, est. 2017). No disclosed quantum portfolio company: a previously listed IQM position was unsupported. Quantum is named only as an NIF-alignment theme; verticals repositioned 2025-2026 as Enterprise AI & Data, SpaceTech & Physical AI, and Novel Computing (the natural quantum hook).
Investment thesis
OTB Ventures is the largest CEE-rooted deep-tech VC, based in Amsterdam and Warsaw (plus Luxembourg), with over $350M under management including a $185M (€170M) Fund 2 closed in 2024 anchored by the NATO Innovation Fund, European Investment Fund and Isomer Capital.
Verticals were repositioned in 2025-2026 as Enterprise AI & Data, SpaceTech & Physical AI and Novel Computing (the natural quantum entry point). Quantum is explicitly cited in the NIF alignment framework (deep tech, defence, security and resilience, with themes including quantum computing), though not yet among disclosed investments.
Check sizes primarily at Series A with 10% allocated to Seed and 50%+ reserved for follow-ons. Genuine geographic unfair advantage in CEE+DACH dealflow that few pan-European funds can match (SEMRON AI chips, ClearSpace debris removal, Kurs Orbital). Defence execution is real: Tytan (Bundeswehr and Ukraine contracts), MatrixSpace (L3Harris), Gen. Rajmund Andrzejczak as strategic adviser.
Differentiated as the fund closest to the Fractal thesis profile (international corridor, deep tech, European sovereignty) with quantum exposure still latent.
