If you're asking what I think you're asking, it's how to find team members and partners who will take a percentage later rather than cash up front now.
Here's the problem: there are lots of great projects out there that never make it. And the equity return on a failed project is below zero, because you can never gain back that time.
And, of course, everybody wants this when they've got the startup, but nobody wants to take the deal unless absolutely everything lines up. I get asked several times a year if I'll work for a percentage of eventual profits, or even an equity stake. I say no in 95% of cases, and even when I've said yes, I've ended up working for free too often.
Also, a delayed-gratification partner not only has no guarantee of success, but also has no way of enforcing the startup doing the things that make success more likely.
These are some of the reasons why, in general, the people who say yes will be hungry--just starting out and not able to attract A-list clients (and fees) yet. And a few of those will get lucky and hook on to something tremendous. Most will lose whatever they put in, because they won't have the skills to ensure that their partner executes properly, and may not have done enough market research to determine if the thing will fly in the first place.
