99designs is a Melbourne, Australia, based company that operates a freelancer platform for connecting graphic designers and clients. The company was founded in 2008, and has a United States office in Oakland, California. 

99designs was founded by Matt Mickiewicz and Mark Harbottle as a spin-off of Sitepoint, a website started in 1998 as a forum for web developers and designers. Designers on its forums began organizing contests based on fictional client briefs.

The founders decided to test charging a fee to post briefs for real projects, eventually creating 99designs as a separate company for the contests.

99designs is the world's largest online graphic design marketplace, connecting businesses looking for design work with more than 200,000 graphic designers from 192 countries around the world.

Businesses can source graphic design work quickly and affordably by launching design contests to the community, working 1-on-1 with individual designers, or purchasing design templates from 99designs' readymade logo store.
