Since you said heuristics, I'll try to leave out my unquantifiable experiences. I also think that the question you are asking is maybe best answered by someone with a Sales or Product background... tho I could be convinced otherwise. -Do you have an idea? -Can you describe the customer? -Can you find example customers? -Can you sell this without a demo or prototype? -If not, which one do you need? -Can you self-produce said demo or prototype? -If not, can you source the talent? -If not, yer f*cked! jk jk Im pushing you toward validating your idea and your passion to do it! But, don't fret- here is my experiential advice: -Form your own LLC, protect yourself. -Dont skimp or cut corners on legal! -Dont focus on only single solution at first, try to map your strengths and passions to a problem. That problem to a custom group. -Goals! Just be real, set some simple quarterly/yearly goals and measure them! Seriously. I have not personally produced a windfall startup, but I have built/consulted for many, and many founders directly... and I run my own consultancy for 20 years now. It can simply be boiled down to, Passion, Problem, Customer. You lack any 1 of the 3, it wont play out nicely.
