On January 15, 2000, after the success of Half-Life, Harrington dissolved his partnership with Newell and left Valve to spend time with his wife.[1] "At Microsoft you always wonder, 'Is it me being successful or is it Microsoft?' But with Half-Life I knew Gabe and I had built that product and company from scratch."[1] According to Newell, Harrington did not want to risk another project after the success of Half-Life.[1]

In 2006, Harrington co-founded Picnik with 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 was the CTO at The Committee for Children from 2016-2018 and is now the CTO of Amplion.[4][5]
