The European Investment Fund (EIF) has announced a landmark $58 Million commitment to Join Capital's third fund, marking its largest investment in the defence sector to date. This significant financial injection, supported by the InvestEU Defence Equity Facility, is designed to accelerate the growth of Europe's defence and deeptech industries. The initiative aims to transition the continent from defence spending announcements to the tangible rebuilding of its industrial capabilities.


A Strategic Push for European Defence Innovation

This investment arrives at a critical juncture as Europe seeks to bolster its strategic autonomy and technological sovereignty. EIF Chief Executive Marjut Falkstedt highlighted the timeliness of the commitment, emphasizing the strategic importance of the space, security, and defence sectors. The backing is expected to attract further private capital, fostering a robust ecosystem for innovative defence solutions across the continent.

Join Capital’s Fund III, which targets a total of $273 million, will channel capital into approximately 25 early-stage deeptech startups throughout Europe. The fund's focus is on companies developing critical capabilities in defence, dual-use technologies, security, and space. This targeted approach ensures that investment is directed toward the most promising and strategically vital areas of innovation.

Fostering a Dual-Use Technology Ecosystem

A key focus of the fund is on dual-use technologies, which have applications in both military and commercial sectors. Jan Borgstädt, a Founding Partner at Join Capital, explained that the firm backs founders whose technologies create an asymmetric advantage for their customers. He emphasized that such investments have a doubling effect, simultaneously creating deterrence and driving economic growth for Europe.

Join Capital's existing portfolio demonstrates its commitment to cutting-edge European innovators. The firm has supported companies like Optics11 in the Netherlands for fibre-optic sensing, Quadsat in Denmark for advanced payloads, and Quantum Optics Jena in Germany for quantum-secure communications. These investments span critical fields from cybersecurity to advanced materials, showcasing the breadth of the fund's deeptech focus.

The Broader European Vision

This initiative aligns with the European Commission's broader strategy to enhance the EU's defence readiness through innovation. Commissioner Andrius Kubilius stated that disruptive technologies are crucial and that investing in specialist venture capital funds strengthens the financial ecosystem. This support is vital for nurturing defence innovators, startups, and SMEs, enabling them to scale up within Europe.

Historically, defence research and development has been a powerful engine for broader technological progress, yielding innovations like satellite navigation and the internet. Join Capital's Fund III aims to continue this legacy by ensuring the next generation of critical technologies is developed and anchored in Europe. This strategy not only enhances security but also promises to reshape civilian life and boost global productivity.


The EIF's $58 Million commitment to Join Capital represents a pivotal moment for Europe's defence and technology sectors. This strategic partnership is more than a financial transaction; it is a clear signal of the continent's resolve to build a self-reliant and innovative industrial base. By empowering deeptech startups, this initiative will be instrumental in securing Europe's future prosperity and strategic autonomy on the global stage.
