Best Websites to Find a Co-Founder

5 min read

Size isn't the same as usefulness. Some of the biggest platforms for this are the least likely to get you a reply, because they weren't built for the specific job of finding a co-founder.

Krooko — purpose-built for this exact problem. A card describes what you're building and who you need; people discover it in a public feed instead of you cold-messaging strangers.

LinkedIn — not built for this at all, but unbeatable if you already know exactly who you're looking for. Search by background and message directly.

Indie Hackers — a community of people building in public. Less a matching tool, more a place where the right person sees your post because they're already there every day.

Reddit (r/cofounder, r/startups) — free and high-traffic. Expect noise, but the reach costs nothing.

Wellfound — technically a jobs board, but usable once you know the specific role you're trying to fill.

CoFoundersLab — a long-running, dedicated platform with detailed search, most useful once you're past the free tier.

The realistic answer is to try more than one at once. A Krooko card takes a few minutes and keeps working in the background while you try the rest.
