  "The Commit to Vote Challenge Facebook app was very effective at engaging people in the voting process, many of whom were otherwise unlikely to turn out. It experienced viral growth soon after launch, and currently has more than a million active users on Facebook. This would not have been possible without the improvements made using Optimizely."

  "The Optimizely tool is very easy to work with and makes web-based page testing a snap. We like how the program is self-contained and not having the extra code on our webservers for creating and running experiments. Optimizely also uses the same url of the page being tested, so we don't have to create a separate page like other testing programs. All-in-all Optmizely is an excellent tool for web page experiments!"

  Kevin Stecko, Founder of 80sTees.com

  "I really love it - Optimizely is making life so much easier for my customers to test their ideas. What I love most is how quickly and easily they can create new page variations without my input. They don't need technical skills or know-how: they simply log in and 30 seconds later they have a new test - incredibly simple and effective."

  "Omniture Test & Target was ghastly. Had to beg to get any split test done and had no clear view of what was the winning version. What Optimizely does is set the marketing or CRO man free from any internal resources. Even if (like me), they aren't designers, or coders but just do marketing. That's Optimizely's real value proposition - autonomy."

  Nicholas Black, CEO of iLeviathan

  "Optimizely makes A/B testing super easy and fun!"
