Stewart Butterfield

Stewart Butterfield is the co-founder of popular photo-sharing website Flickr and its parent company Ludicorp with his wife Caterina Fake. In April 2009, he was reported to be leaving his position at Flickr to start a new stealth social gaming company with Cal Henderson.

In March 2005, Fake and Butterfield sold Flickr to Yahoo barely a year after launching it, reportedly for more than $30 million. Butterfield remains with the company, and serves as Director of Product Management.

He has also founded the 5k competition, served on the W3C’s XForms working group, been nominated for a Chrysler Design Award, and is a frequent speaker on design and technology topics at professional and academic events across Europe and North America.

On June 13th, 2008 Stewart sent in his resignation letter.
