Blossom Capital

Ophelia Brown is the founder and managing partner, and she leads the investment committee. Her background includes partner-track roles at Index Ventures and LocalGlobe, where she sourced early-stage enterprise deals across Europe. Investment decisions are made by a small partnership group, consistent with the firm's deliberately lean team structure.

The firm relies on founder referrals and direct operator relationships built across the European ecosystem. Ophelia Brown's network from her Index Ventures and LocalGlobe years provides access to early-stage rounds that US co-investors like Accel also back. Blossom uses an internal data platform to track signals from developer communities and startup ecosystems, but the primary sourcing channel remains personal relationships with repeat founders.

Blossom runs a concentrated portfolio of roughly five to six new investments per fund, in contrast to the 25-to-30-position approach typical of European seed funds. The firm writes larger initial checks—$5 million to $10 million—and reserves significant reserves for follow-on rounds. This mirrors the high-conviction model more common among top-tier US funds than European peers.

The firm invests from Seed to Series A, with a focus on leading or co-leading rounds where it can secure meaningful ownership. The typical initial check size ranges from $5 million to $10 million, with capacity to follow on in later rounds. Blossom does not invest at pre-seed or growth stages.

The firm does not invest in consumer internet, hardware, or life sciences. Its mandate is strictly enterprise-focused, covering software infrastructure, developer tools, fintech, cybersecurity, and applied AI. Geographic scope is limited to Europe, with a concentration in London, Stockholm, and Berlin.

Blossom invests exclusively through direct equity deals in portfolio companies. The firm does not act as a fund-of-funds, nor does it make LP commitments to other venture managers. All capital is deployed directly into the startups it backs.

The firm actively co-invests with US multi-stage funds, including Accel and Index Ventures, on rounds where European startups seek both local and transatlantic backing. Blossom typically leads or co-leads seed and Series A rounds, rather than taking passive minority positions alongside larger investors.
