Join Capital

High-Level Overview

Join Capital is a European early-stage venture capital firm with a focused mission: to back deep tech startups that are building foundational technologies to solve the world’s toughest industrial, enterprise, and defense challenges. The firm invests at the intersection of hardware and software, prioritizing companies whose innovations can lead, scale, and endure over time—not just chase headlines. Its investment philosophy centers on early, concentrated bets in Seed and Series A rounds, where it often leads or co-leads, and maintains a long-term, hands-on partnership with founders.

Join Capital’s portfolio is concentrated in “New Industry” sectors, including advanced manufacturing, robotics, AI & cybersecurity, quantum & advanced computing, space & aerospace, and autonomous systems. It targets B2B and industrial tech startups that are digitizing core business functions such as operations, supply chain, data analytics, and software development. By backing technical founders and helping them evolve into strong business leaders, Join Capital plays a strategic role in shaping Europe’s next generation of industrial and defense tech champions, accelerating the continent’s technological sovereignty and industrial edge.

Origin Story

Join Capital was founded in 2017 as an early-stage venture firm based in Berlin, with additional offices in London and Milan, reflecting its pan-European outlook. The firm was built around the conviction that Europe has a strong base of deep tech talent—especially in engineering and industrial innovation—but often lacks the patient, sector-specialized capital and operational support needed to scale globally. From the outset, Join Capital positioned itself as a partner for technical founders building in complex, capital-intensive domains where domain expertise, long development cycles, and strong IP matter.

Under the leadership of founding partner Tobias Schirmer and the broader team, Join Capital has evolved from a first fund into a multi-fund firm now deploying from its second fund of €112 million, with over €150 million in total assets under management. Early investments in industrial software, robotics, and defense tech helped define its identity, and over time it has sharpened its focus on deep tech with applications in enterprise, industry, and national security. Its backing by institutional investors like the NATO Innovation Fund and KfW Capital has further cemented its role as a strategic player in Europe’s innovation infrastructure.

Core Differentiators

Deep Tech Focus with Industrial & Defense Lens
Join Capital specializes in deep tech with real-world impact—particularly in industrial, enterprise, and defense applications. Unlike generalist VCs, it actively seeks out startups working on advanced materials, quantum systems, autonomous robotics, and secure computing, where technical moats and long-term defensibility are critical.

Sector-Specialized, Hands-On Support
The firm doesn’t just write checks; it operates as a strategic partner. Join Capital supports portfolio companies through

• Commercial acceleration via its Join Ambassador Network, connecting startups with industrial corporates for validation and go-to-market.
• Follow-on funding and exit guidance, helping founders navigate later-stage rounds and potential acquisitions.
• Active board participation, with partners engaging directly on strategy, hiring, and scaling.

Leading Early, with Meaningful Checks
Join Capital typically invests €1–5 million in Seed and Series A rounds, often taking a leading or co-leading role. This allows it to shape cap tables, set strategic direction early, and build strong alignment with founders from day one.

Pan-European Platform with Strategic LPs
With offices in Berlin, London, and Milan, Join Capital has a strong footprint across Europe’s key tech hubs. Its LP base includes strategic institutions like the NATO Innovation Fund and KfW Capital, which not only provide capital but also open doors to defense, space, and industrial ecosystems.

Track Record in Tough Tech
Since inception, Join Capital has backed around 25 companies and achieved multiple exits, demonstrating its ability to back complex, long-cycle businesses and realize returns. Its portfolio includes companies in quantum communications, RF geolocation, and advanced manufacturing—areas where few VCs have the appetite or expertise to play.

Role in the Broader Tech Landscape

Join Capital is riding several powerful macro trends reshaping the global tech landscape: the resurgence of industrial tech, the rise of European technological sovereignty, and the growing convergence of defense, space, and commercial deep tech. As global supply chains reconfigure, industries digitize, and geopolitical tensions increase, there is a growing demand for resilient, secure, and sovereign technologies in manufacturing, logistics, cybersecurity, and space.

Timing is in Join Capital’s favor. Europe is now prioritizing strategic autonomy in critical technologies—from semiconductors and quantum to space and defense—and governments are backing innovation through funds and procurement. Join Capital sits at the nexus of this shift, acting as a bridge between deep tech founders and the industrial and defense ecosystems that need their solutions. By focusing on “foundational” rather than “flashy” tech, it helps de-risk Europe’s innovation pipeline and strengthens its ability to compete with the U.S. and Asia in hard tech domains.

Moreover, Join Capital is helping redefine what a European VC can be: not just a financier, but a builder of strategic strongholds. Its emphasis on long holding periods, late-stage capital readiness, and institutional LPs signals a move toward more mature, outcome-oriented venture models that can support companies all the way to IPO or major exit.

Quick Take & Future Outlook

Join Capital is well-positioned to become one of Europe’s defining deep tech VCs of the next decade. As the line between commercial and defense tech continues to blur—and as industries demand more robust, secure, and intelligent systems—the firm’s focus on foundational industrial and enterprise technologies will only grow in relevance. Its next chapter will likely include larger follow-on investments, more cross-border expansion for portfolio companies, and an even stronger role in shaping Europe’s defense and space innovation ecosystems.

Looking ahead, Join Capital’s influence will expand beyond capital allocation into ecosystem building: fostering talent, shaping policy conversations around tech sovereignty, and helping Europe close the gap in hard tech scale-ups. For founders building in complex, capital-intensive domains, Join Capital represents a rare combination: deep sector expertise, long-term conviction, and a genuine commitment to building companies that can lead, scale, and last. In a world where resilience matters more than virality, that’s exactly the kind of partner the next industrial edge will need.
