Like marriage, it is worse to marry a wrong person than stay single. Therefore, if you do not really trust your cofounder, don't let her become your cofounder because a wrong cofounder is worse than a solo founder.

As a seed round investor, I do not view a solo founder as a negative sign since I am personally a solo founder so I know a solo founder can work well.

However, the ideal founding team shall be two cofounders - The product guy looks after products and the business guy looks after customers. Then the startup life can be much easier for both cofounders.
