Good point - finding domain expertise for product/market fit is super important.

However, that's not something that is solved purely by capital. It also takes a lot of time (in practice, you need potential customers to describe their problem multiple times over multiple meetings, since what they think they want, what you think they want, and what really solves the problem take time to converge). For our company (applying ML/NLP in the customer feedback domain), finding domain experts willing to contribute their guidance took a while, but has been one of the most important things we've done.
