OTB Ventures

OTB Ventures is a European deep technology venture capital firm founded in 2017 and headquartered in Amsterdam, Netherlands, with a significant operational presence in Warsaw, Poland, managing over $300 million across multiple funds and operating a dedicated OTB Space Program that makes strategic investments in European space technology companies.

The firm is one of the largest venture capital managers in Central and Eastern Europe by assets under management, focusing on frontier technology sectors including space technology (SpaceTech), artificial intelligence, financial technology (FinTech), and cybersecurity. OTB Ventures is backed by institutional investors including the NATO Innovation Fund — a $1 billion multi-sovereign defense technology investment vehicle established by NATO member nations — and the European Investment Fund (EIF), part of the European Investment Bank Group providing pan-European institutional capital to growth technology sectors.

OTB's Space Program invests across the space value chain: Earth observation data and analytics, satellite communications infrastructure, launch services technology, space manufacturing, and dual-use defense-relevant space capabilities. The NATO Innovation Fund backing creates a natural mandate toward dual-use technologies — space systems with both commercial and defense applications — reflecting NATO member nations' interest in developing sovereign space capabilities independent of non-allied suppliers.

OTB Ventures leverages its Central and Eastern European network to source investment opportunities in Poland, Czech Republic, Estonia, Romania, and other EU member states with growing space engineering talent pools and government space ambitions. The firm competes with Airbus Ventures, Seraphim Capital, and JEDI Ventures for European space technology deal flow, while its CEE focus provides differentiated access to geographies underserved by London and Silicon Valley-focused venture funds.
