I think I've asked this question but I found myself a cofounder with 2 others that prioritized too highly IMO coffee meetings with "investors", no name board advisors, expensive conferences, and basically everything on that list. My approach was to gently voice my concern and but also let them do it in the hopes they'd see how useless it was. The other thing that didn't help was I was the "technical cofounder" and the attitude essentially was I didn't "get" business, and sometimes I wondered if they were right.
Interestingly both were woman, and I don't recall too much of #3. They definitely participated in women in tech type groups but I thought it was no different than any other useless networking others that aren't focused would do.
This will be definitely something I probe for in the future. Anyone looking for a cofounder? (I'm serious, and I have a cool little project we could do to see if we can build something people want together)
