Carta data shows that solo-founded startups grew from 23.7% of all new companies in 2019 to 36.3% by mid-2025; and in March 2026 alone, 580,612 new businesses were registered in the U.S., a 14% jump year over year.

More founders, fewer co-founders. I've been thinking about what that actually means.

Part of it is AI lowering the cost of early execution; one person can now do what used to require a small team. That's genuinely good. But part of it is something I'd push back on: the solo founder narrative has been quietly romanticized to the point where asking for help feels like weakness, and building in community feels optional.

It isn't optional. The data on founder mental health is consistent and brutal; isolation doesn't just hurt the person, it hurts the company. The decisions you make alone at 11pm are not the same decisions you'd make with a peer you trust sitting across from you.

Ecosystems exist precisely because building alone is inefficient in ways that don't show up on a cap table. If you're a solo founder and you don't have a community around you, that's not independence; that's a risk factor you haven't priced in yet.
