Inc. magazine is turning 35 years old this year! To commemorate the occasion--and to let down our ever-so-slightly graying hair--we're revamping our annual 30 Under 30 Coolest Entrepreneurs list. For this year only, we're welcoming applications from those under age 35.

While slightly older founders are now invited to participate in the publication's annual search for the next Mark Zuckerberg or Aaron Levie, the other criteria remain the same: We're looking for young(ish), smart and disruptive entrepreneurs who can prove they've got a business with traction and verve.

In addition to bragging rights for life, winners may be featured in Inc. magazine or on the publication's award-winning website.

But we're not just handing out this honor out. Applicants (who must be 35 or younger at the time of application) will be reviewed by a panel of judges. The final list will be announced at the end of June. Think you have what it takes?
