I agree. I think the biggest consideration with this should be the potential opportunity cost (equity, control and the risk of future fall-outs) of taking on co-founders.

And in a similar vein to how I feel about bootstrapping vs external funding, I think if you can be a solo founder until V1, you can leverage that traction in taking on co-founders. That way your hands isn't forced and you don't necessarily have to sacrifice large amounts of equity.
