EIF makes largest defence investment yet with €50M backing for Join Capital

European Investment Fund Backs €50M Defence Tech Push as Europe Rebuilds Industrial Might

In a decisive move to strengthen Europe’s technological and industrial base, the European Investment Fund (EIF) has committed €50 million to Join Capital’s third fund, marking its largest-ever investment in defence. The move comes as Europe pivots from defence spending announcements to tangible rebuilding of its industrial capabilities.

The commitment is supported by the InvestEU Defence Equity Facility, a flagship initiative designed to bolster Europe’s defence technological and industrial base by backing venture capital funds focused on dual-use and critical technologies. This injection of capital is seen as a catalyst for a broader wave of investment into Europe’s defence innovation ecosystem.

Join Capital’s Fund III, with a target size of €235 million, will back 25 early-stage deeptech startups across Europe. These companies are developing technologies with critical applications in defence, dual-use, security, and space—sectors increasingly recognised as strategic priorities for the European Union.

The Berlin-based VC firm has a track record of backing pioneering defence and deeptech innovators. Among its portfolio are Optics11 (Netherlands), which develops fibre-optic sensing for critical infrastructure; Quadsat (Denmark), advancing defence-grade RF geolocation technology; Kreios Space (Spain), focused on space-based solutions; Quantum Optics Jena (Germany), a leader in quantum-secure communications; and 2D Photonics (Italy), working on advanced electronic payloads and cybersecurity.

“We back founders whose technologies create an asymmetric advantage for their customers in the military and commercial industry,” said Jan Borgstädt, Founding Partner at Join Capital. “Investments in such dual-use technologies have a doubling effect—they create both deterrence and economic growth for Europe.”

The timing of this investment is critical. With geopolitical tensions rising and the EU placing greater emphasis on strategic autonomy, the need for homegrown innovation in defence and security has never been more urgent. The EIF’s backing is expected to unlock further capital from institutional and private investors, accelerating the growth of Europe’s defence tech ecosystem.

EIF Chief Executive Marjut Falkstedt underscored the strategic importance of the move: “This investment, backed by the InvestEU fund, could not come at a better time, given the strategic importance attached to the fields of space, security and defence. With this backing, we are confident that additional investments will follow, helping Europe in building a robust ecosystem for innovative defence solutions.”

EU Commissioner Andrius Kubilius echoed the sentiment, emphasising the role of innovation in the EU’s defence readiness. “Innovation and disruptive technologies are crucial for the EU’s defence readiness. By investing in specialist defence venture capital funds like Join Capital, the Commission and the EIF are strengthening the financial ecosystem that nurtures and supports our defence innovators, startups, and SMEs to grow and scale up in Europe.”

This €50 million commitment is more than just a financial transaction—it’s a signal of intent. As Europe seeks to reduce its reliance on external defence technologies and build a resilient, innovative industrial base, investments like these are laying the groundwork for a new era of European defence and deeptech leadership.
