We've all waited in line at Starbucks for more than 10 minutes. We've all thought, "There's got to be a better, faster way to get my triple grande soy latte with extra foam." I've thought about it; most of us have but never did anything about it. Noah Glass did something about it.

From that very scenario, Glass created GoMobo . It turns your cell phone into a mobile credit card. That way, you get your caffeine fix quicker and beat the line getting takeout at your favorite lunch spot.

At 25, Glass is the CEO, with employees who finished business school before he was born. Glass deferred Harvard Business School after graduating from Yale University on the hunch that people hated waiting in line as much as he did.

Now he has a hunch that urban professionals and other twenty-somethings don't like waiting for much of anything, including movies tickets or cabs. So, Glass plans to expand GoMobo to include those services. This way, you can use those extra minutes you'd use to wait for and pay for your stuff to think of ways to solve bigger problems. Just leave the small stuff to Glass.

A lot guys in their early twenties are out partying all night and "figuring it out" during the day. But not 24-year-old David Hauser, pictured right, and 25-year-old Siamak Taghaddos. These young entrepreneurs are seizing the day and the night.

Hauser and Taghaddos founded GotVMail , a company based in Boston that basically makes the small business owner look like a really big deal by providing them sophisticated, personalized voicemail service. Catering to the little guy has made the GotVMail guys big money. The company has been profitable since its second month and now has revenues of $5 million a year.

Hauser and Taghaddos met when they were undergrads at Babson College, a school known for turning out entrepreneuers. They both started their own companies in high school. They don't sleep much now and didn't sleep much then -- but, then again, who can when you're busy seizing your youth?
