Investment Thesis

byFounders is described as "the community-powered VC of the New Nordics," a Copenhagen-based early-stage venture fund that invests in globally ambitious, impact-aware founders. The fund positions itself as founder-friendly, with a philosophy rooted in transparency, partnership, and positive impact on the world. Their core thesis is that superior financial returns come from investing in companies contributing to a better tomorrow—balancing pure financial returns with responsible, impact-aware investing.

The fund explicitly targets "globally ambitious & impact-aware founders" and welcomes founders who demonstrate commitment to running their business responsibly (integrating ESG considerations into operations/decision-making) and prefer backing startups with positive social or environmental impact.

Stage Focus

byFounders is explicitly an early-stage investor with a sweet spot in pre-seed and seed. They state "we like to be the company's first investor" and emphasize "the earlier we get in the more useful we are."

Stage distribution:

  • Pre-Seed: Primary focus
  • Seed: Primary focus
  • Series A: Selective follow-ons

They make approximately 8-15 new investments per year, maintaining a disciplined, founder-focused approach to deal sourcing and evaluation.

Check Size

Based on their FAQ and website: "On average, our ticket size ranges between EUR 500K to 4 million."

  • Pre-seed: €500K-€2M
  • Seed: €1M-€4M
  • Series A follow-ons: Varies

Lead Tendency

byFounders explicitly leads rounds. They state "Yes" to the question "Do you lead rounds?" and provide check size information with clear ownership targets. Given their emphasis on being the first institutional investor and their platform-driven approach with operational support, they are definitively lead investors.
