We’re betting
on you

Founding a company is probably the hardest thing you’ll ever do.

But here’s the thing: You’re not alone. Say hello to your support system; your middle-of-the-night ideas team; your foundational network of people who can actually say, We’ve been there, too.

K50 has a long history of supporting our community from the start, beginning with the inaugural K50 Summit in 2008. Today, our founders are redefining the future for the 99%, and, yes, we’re still with them every step of the way.
