I'll share my story.

Solo technical founder. Hired my first sales employee long after I established a product-market fit, got a few paying customers and $300K in annual revenue. I gave him a co-founder title, but we were never equal. It was one of the best decision that I have made. The company would not have been able to survive if 2 of us were equal - we would have gone out of business. Instead, 1 year after I pushed him out we had a moderately successful exit (8 figure).

I think that having a solo founder is beneficial AS LONG AS that one person is great. Otherwise you, as a VC, kind of bet that at least 1 of them will be great and it will all work out.
