Is there any forum or group that has people that can advise on such matters?
I know HN is one but it's too big/too impersonal for this.
I mean a place for founders to find "mentors" (i.e. people with more experience or people that have done similar things before) that would be willing to help them with things as a sale to a big company or how to structure a deal.
There’s a global peer group called Entrepreneurs Organization I’ve been part of for five years that satisfies this for me. It’s for founders/owners with $1m+ in revenue. 14,000 members around the world broken up into smaller chapters. The NYC chapter has 200 members, for instance. eonetwork.org
YPO is another one, though for larger companies ($8+ million in revenue).
I'm in a program in NYC called https://www.venwise.com/, it's a moderated CxO peer group that meets for a long session every month and does exactly this.
