It's called Wahooly, and promises you a piece of the pie for hundreds of startups in the coming year. The way it works (in theory) is you as a blogger/tweeter use your influence to promote a company. In turn, this company gives you a stake in the profits.
This includes Wahooly itself. They offered 25,000 spots for people to split a 5% profit share in the company. Yes, that means that I'm only getting 2-ten-thousandths of a percent, but that means I get $100 for every 20 million this company makes.
Not a lot of cash, no. But I'm not exactly putting 40+ hours a week into this.
Their goal is to show followers about 200 startups in 2012. The design will be similar: Use your influence to promote the startup, and get a piece of the profit pie.
Imagine if Facebook did this long long ago...
I'm not sure if there are any spots left, but give Wahooly a look. I received my invite due to a high(ish) Klout score, so there may be some criteria to get in. Regardless, money is money. Check it out.
And if you see a lot of Twitter-spamming coming from me about @TeamWahooly, you'll know why.
