SAN FRANCISCO, May 5, 2014 /PRNewswire/ -- Optimizely, today celebrates passing a milestone of seven billion web experiences optimized. Fueled by rapid product expansion and high demand, the company has achieved triple digit year-over-year growth in annual revenue since launching in 2010.

"Optimizely is the clear leader in the new—and incredibly crucial—software category of website and mobile optimization," said Scott Weiss, general partner at Andreessen Horowitz. "Testing and personalization powered by Optimizely gives businesses the ability to use data-driven decisions to provide users with a better experience. Optimizely represents the future of highly efficient product and business development, enabling users without technical expertise to run tests and achieve immediate results." Weiss joins Optimizely's board of directors.

Currently, Optimizely customers:

• Have created more than a half million experiments
