Nope, this isn't how the real world/VC/PE works.
You absolutely need your own capital/skin in the game if you ever want LP/investor commitment.
No one is going to give you money just because you have an "idea." Oh, and remember that every pitch/meeting is all or nothing: you need to have a bulletproof business plan, how much capital you need (will this be through debt or equity), and how you've executed (yes, you need to show a track record) and will continue to execute.
But I think the amount of equity needed isn't as Mich as folks are putting off...
VC funds are frothing at the mouth for new ideas because the market is saturated with investors and there's a lot of cash flowing around...
Go look up the top 50 startups from MBA programs and see how Mich capital they raised.
Some cats from Harvard raised $325M...
A chick from Houston raised $10M
You don't have to have as much cash in it as people are saying in here...
People have a ton of cash from becoming liquid during the recession... People want mega returns that beat the bull run we are..
And what better way to get it than finding the next Facebook?
