DAN SIROKER is the cofounder and CEO of Optimizely. The inspiration for Optimizely came from Dan's experience as the Director of Analytics for the 2008 Obama Presidential campaign.

Dan was formerly a product manager for Google Chrome and AdWords.

PETE KOOMEN is the co-founder and President of Optimizely. After earning his MS 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 Y Combinator winter 2010 class. In between mountain climbing adventures, Pete runs product, engineering, and design at Optimizely.
