Isomer Capital

Isomer Capital positions itself as the premier venture capital partner across the European innovation ecosystem. Founded with the mission to identify and support the continent's most promising fund managers, Isomer takes a distinctive two-pronged approach to investment: first backing emerging VC firms during their formative stages, then strategically co-investing alongside these partners in their standout portfolio companies. This dual strategy allows Isomer to cultivate relationships with Europe's next generation of venture capital talent while simultaneously gaining direct exposure to high-potential startups across multiple sectors and geographies.

The firm has established a reputation for its discerning selection process when evaluating fund managers, focusing on teams with specialized domain expertise, proven operational experience, and demonstrable value-add capabilities beyond mere capital provision. Isomer typically engages with VC firms raising their first, second, or third institutional funds—a critical juncture where their support can significantly influence trajectory and success. Through this approach, Isomer has built an extensive network spanning over 40 European VC partnerships, creating a proprietary deal flow pipeline that provides unique visibility into thousands of European startups at various development stages.

On the direct investment side, Isomer leverages insights gained from its fund manager relationships to identify exceptional companies for co-investment opportunities. The firm typically participates in Series A through C funding rounds, deploying capital alongside its VC partners in companies demonstrating strong product-market fit, scalable business models, and international growth potential. This approach has allowed Isomer to build a diverse portfolio across multiple sectors, with particular strength in enterprise software, fintech, healthtech, and deep technology ventures. Their investment thesis emphasizes companies with pan-European or global ambitions that can achieve category leadership positions.

Beyond financial capital, Isomer provides significant strategic value to both fund managers and portfolio companies through its extensive network of limited partners, industry connections, and operational expertise. The firm actively facilitates cross-border expansion, talent acquisition, and subsequent fundraising efforts for its portfolio. With offices in London and key European innovation hubs, Isomer maintains close proximity to emerging technology clusters while offering a truly continent-wide perspective. This positioning has established Isomer as a trusted connector between European innovation and global capital markets, helping to address the historical funding gap that has challenged European startups compared to their American counterparts.
