Dan Siroker is the co-founder and CEO of Optimizely. The inspiration for Optimizely came from Dan's experience as the Director of Analytics for the 2008 Obama Presidential campaign. Optimizely is the product Dan wishes he had back then to make it easy for anybody to do A/B testing. In 2012, Forbes named Dan one of the Top 30 under 30 in Technology. Dan was formerly a product manager for Google Chrome and AdWords.
Pete Koomen is the co-founder and President of Optimizely. After earning his M.S. in Computer Science from the University of Illinois at Urbana Champaign, Pete joined Google as a product manager where he helped launch and grow Google App Engine to more than 150,000 developers. In 2009, Pete teamed up with Dan to start their first company, CarrotSticks, an online math game for kids. Less than a year later, Pete and Dan created Optimizely during the YCombinator winter 2010 class. Pete runs product, engineering, and design at Optimizely.
