If you need to meet with 100 investors to raise money you are promoting a shitty deal and you shouldn't be investing your personal time in it.
Conversely, if 500 startups routinely invests in companies where 90+ other investors already said no, you gotta worry about 500 startups.
> So, I made up a rule of thumb: 5-100-500. Over 5 weeks, meet with 100 investors to close $500k in your seed round. If you want to close $1m, double all of these numbers.
