## About

Lagoon Capital traces to 2007 when Ari Korhonen established the office following the 2004 exit of Komartek to WM-Data. Korhonen had built the energy and utilities software business into an international operation before shifting to full-time investing. The office targets seed and early-stage rounds in SaaS, fintech, gaming, AI, IoT, and marketplace businesses. It deploys direct co-investments, SPVs, and commitments to venture funds while maintaining a geographic reach across Europe and North America. Korhonen serves as senior advisor and investment committee member at Spintop Ventures, growth partner at Evli Growth Partners, and investment committee member at Seedcamp. He also holds an advisory board seat at Finnish Industry Investment. Confirmed positions include multiple Finnish and international startups that reached exit through these channels. The office has backed 54 startups through 165 angel checks and 30 venture fund commitments, producing 12 exits to date. Ari Korhonen remains the sole named principal and operates without additional disclosed offices. He maintains active roles on the boards of FiBAN, EBAN, and EstBAN, and serves on the advisory board of LUT University. No operational events from the past 24 months appear in public records. The structure differs from typical family offices through its explicit requirement that portfolio companies already demonstrate revenue traction before investment. Korhonen sits on most boards or advisory groups and leads rounds when needed, creating a repeatable pattern of operational involvement rather than passive capital allocation.
