I had a brilliant sales cofounder but ultimately he didn't take an equal share. He was basically a 10x salesman. I worked with a lot of startups and he managed to cover about a month of "customer validation" in a day. But basically I ended up taking product, logistics, & engineering and it wasn't a fair split. I think we made the mistake of not making him CEO. The CEO always has to be present when pitching to a major investor. So it ended up being me doing the pitching and I never had time to work on the product. The product guy also tends to be the CEO. We learned from that mistake and he went on to be a CEO of a million dollar startup running on WordPress. Sadly, they focused on sports and didn't do well during covid.
