Investment thesis

CircleRock Capital is a leading multi-stage venture capital syndicate that co-invests alongside top global VC firms in exceptional technology companies from Seed through Series B across Europe, the UK, and the US. They operate a conviction-driven strategy, investing selectively on a deal-by-deal basis and scaling into breakout companies to secure meaningful ownership. Initial ticket sizes typically range from €500k-€5m. The firm does not lead rounds or take board seats, allowing founders to maintain control while benefiting from CircleRock's extensive network and fundraising expertise. Their limited partners include exited entrepreneurs, leaders at global tech companies, venture-backed founders, family offices, leading angels, CEOs, and board members of public companies. They are sector agnostic but focus on visionary founders working on defensible technology in internationally scalable markets.

Notable quotes

I love founders with specific knowledge of a certain industry who exude a subtle confidence in the certainty of their success.

Conor Sharpe · Maddyness UK · 2024-01-08

One of the simplest things a founder can do is write a regular investor update, but surprisingly many don't. Investors want to hear the good and the bad news, and how we can help. A founder is far more likely to receive follow-on funding from us if we have been kept in the loop throughout the entire journey.

Conor Sharpe · Maddyness UK · 2024-01-08

Our approach is very much non-consensus, as every other emerging manager has tunnel vision to set up a fund. However, we love the flexibility of our model as we can invest at any stage, in any geography and in any industry!
