Do you need a cofounder to start a startup?

Updated Oct 1, 2026

Short answer: No — solo founders do build and fund successful companies. But a cofounder with complementary skills shares the workload and risk, and many early-stage investors prefer backing a team.

When a cofounder helps most

If the company needs skills you don't have — building the product, selling, or a regulated domain — and you can't afford to hire for them, a cofounder fills the gap with ownership rather than salary.

When going solo can work

Solo founders often succeed when they can build the first version themselves, or when the business can grow on revenue rather than outside funding.

If you do look for one

Be clear about the gap you need filled and the commitment and equity you expect. Find a cofounder who already matches those expectations.
