What are your thoughts here on top three priorities BEFORE this stage?
(I would say,
1. Don't give up equity, keep your credibility, don't be full of hot air. (If a dozen people think you're kind of cofounding this with them and your paperwork is a mess, you're dead on arrival!)
2. Keep dedicated and always do SOMETHING that moves you closer to "Once you have built your product and it’s in the market..." (I say this as a technical single founder, obviously it goes double if you CAN'T do the technical side.)
3. Reach out and network, even well ahead of product or need for money or in the case of talent, for this particular talent. No one will look down on you for saying, "You know I'm nowhere near the normal time to seek funding (or to bring you on board, or whatever), but I thought I would mention that I'm working on this..." Do welcome any feedback. The fact that you're putting feelers out even while it's too early can't bite you (unless you're always full of hot air, see #1), as if nothing else (I expect) you can refer back to this contact instead of taking up contact totally 'cold', when the time does come.
What do you guys think? Of course, these days #2 can be "Move your team to the Bay Area. Get funded. Funded for what? We'll cross that road when we get there, sheesh!"
Not that there's anything wrong with that...)
