On January 15, 2000, after the success of Half-Life, Harrington dissolved his partnership with Newell and left Valve to take an extended vacation.
Harrington returned to the software industry in 2006, when he co-founded Picnik with long-time friend and former colleague Darrin Massena, which was later acquired by Google in March 2010. Harrington left Google in March 2011, and co-founded another company with Massena, called Catnip Labs, in January 2012. Harrington is currently the CTO at The Committee for Children.
