After a co-founder cost me $850K and a $3M lawsuit, I built Prosperity Syndicate alone. The question I get most from solo founders is whether investors will hold the solo path against them. The honest answer is more useful than yes or no.
Investors do not require a co-founder. They require evidence that the things a co-founder usually provides exist anyway. Solo is not a weakness. An unsupported solo founder is.
What a co-founder is supposed to provide
On paper, a co-founder gives a company complementary skills, shared decision load, resilience if one person falters, and a check on the founder's blind spots. Those are real needs. The mistake is assuming a second name on the incorporation is the only way to meet them. Investors are not attached to the structure. They are attached to the outcomes the structure is meant to produce.
How a solo founder shows the same strength
A senior team or fractional leadership that covers the skill gaps. An advisory bench that provides the outside judgment a partner would. Systems and documentation that prove the company does not live entirely in one head. And a clear, honest answer to the resilience question: what happens to this business if you are out for a month. A solo founder who can answer that calmly is more fundable than a pair who cannot.
Investors do not fund a co-founder. They fund the certainty that the work gets done. Solo founders just have to show it differently.
Turn the solo story into an asset
Built alone, after a partnership that nearly ended everything, is not an apology. Told well, it is proof of judgment: you understand the cost of the wrong partner, you chose structure over a warm body, and you built the support a company needs without surrendering its direction. That is a story investors respect, because it is the story of a founder who has already learned the lesson most learn far more expensively.
