Icebreaker invests in accomplished operators, often domain experts from companies like Rovio and Pipedrive, before they have a fully formed startup, helping them find co-founders, advisors, and the confidence to leave their day jobs through a structured, community-driven system with dedicated teams for founder development, hiring, and growth. This approach has led to strong follow-on funding results, and the firm backs its winners further through a dedicated Opportunity Fund, while staying comfortable investing in complex, expert-led fields such as cybersecurity, tax technology, and climate markets.
