Isomer Capital

Isomer Capital is a London-based venture capital firm established in 2015, known for its distinctive dual investment strategy. They primarily operate as a fund-of-funds, committing capital to leading European venture capital funds, while also making direct co-investments into high-potential European technology companies. This approach allows them to gain broad exposure to the European tech ecosystem while also participating directly in the growth of specific portfolio companies.

The firm's direct investment strategy is characterized by its focus on co-investments and follow-on rounds, typically alongside or into companies from their portfolio funds. Unlike traditional VCs that often lead early-stage rounds, Isomer Capital acts as a strategic partner, leveraging the expertise of their network of underlying funds. Their direct investments are generally into companies that have already demonstrated significant traction, often participating in Series A, B, or later-stage funding rounds. Isomer Capital has successfully raised substantial capital, with their total funds exceeding €600 million since inception, including their latest vehicle, Isomer Capital III, which closed at €300 million in 2023.

When making direct investments, Isomer Capital typically deploys cheques ranging from €1 million to €10 million, reflecting their participation in significant growth rounds rather than initial seed capital. Their portfolio includes several prominent European tech success stories, such as Graphcore, Revolut, and Darktrace, showcasing their ability to identify and support companies with global ambitions. This strategic positioning allows Isomer Capital to be a significant player in the European venture landscape, providing capital and support to both fund managers and innovative startups. Their emphasis on collaboration and follow-on investing underscores their commitment to fostering long-term growth within the European technology sector.
