It really depends on the ticket size, traction in the industry, and the industry itself. Having contacts is helpful, but for me it's not really the contacts only. I'd rather understand how much I'm going to make and of course how much I'm going to need to learn. Whenever I took on such a venture (which I did a couple of times), I try to find similar industries or where I have a knowledge base already of the personas, their problems, and the lingo.
