Y Combinator Group Partners Dalton Caldwell and Michael Seibel in front of the text "Business Co-founders?"

Whether or not you need a co-founder is always a hotly debated topic — but going one level deeper, founders often wonder what kind of co-founder they need.

In a prior video Michael and I explained why every software company should have a technical co-founder. But it’s also common for technical founders to be told by investors and advisors that they would benefit from a co-founder with non-technical expertise in things like business or marketing.

Are they correct? In this episode of Dalton & Michael we dive into exactly that question.
