Greens invests in Nordic pre-seed startups with founders who are alumni of Nordic Unicorns. We’re over 50 Spotify alumni who’ve joined together to help the next generation of Nordic startups succeed. Most of us are still active operators at some of the quickest growing companies in the Nordics and across a full spectrum of disciplines. A big part of our motivation is to share hands-on experience, domain expertise, open our collective network of talent & early customers, and pay it forward. Ideally, we’re your first investor - joining you as an early partner together with friends & family while you’re still in stealth mode and based on personal recs from previous colleagues who we know.
