TL;DR: Networking in male-dominated investment circles as a European founder requires three things working together: getting inside the right physical and digital rooms where investors already spend time, building credibility before you need it through public signals of expertise, and converting warm introductions rather than cold outreach. Women-led startups receive less than 3% of European venture capital not because of weak ideas, but because of network exclusion. The fix is strategic, deliberate, and completely learnable.
