A standing thread for the thing that is hardest to find — the specific person who has done the thing you are about to do.
Post what you are building and what would actually help: a collaborator, an introduction, someone who has priced this before, a second opinion on an offer, a podcast guest, or a person who has already made the mistake you are heading towards.
Be specific. "Looking to connect" gets nothing; "I am pricing a first corporate training package and have never sold to procurement" gets answers.
