>i'm dumping 15k in, the last of my savings.. i'm all in
Was a big, red flag for me. Would you dump your life savings into lottery tickets? Don't delude yourself...a startup is just about as hopeless as winning the lottery. You said you've worked at startups. I imagine you've seen, first hand, what the chances of success are.
Seriously, don't blow your emergency fund on the lottery. I know this is a very anti-HN comment, but realistically (statistically!) most startups end in financial failure.
Set aside 6 months of expenses, use the rest of the money to bootstrap your idea as much as you can. Outsource as much as you can afford and get as much traction as feasibly possible. Aim to be profitable from day one.
If you aren't profitable by time you start depleting your emergency fund, THEN consider funding if you think you have a viable product. Or just get a job to help pay for it.
