Optimizely CMS is an American company that specializes in digital experience platform (DXP) software as a service. Founded in 2010, it provides tools for A/B testing, multivariate testing, website personalization, feature toggling, content management, and digital commerce. The company aims to help businesses optimize their digital experiences and improve customer engagement across various channels. In October 2020, Optimizely was acquired by Episerver, which subsequently rebranded the combined entity as Optimizely in January 2021.
Optimizely CMS was co-founded by Dan Siroker and Pete Koomen, both of whom previously worked at Google. The company gained initial traction by participating in the Y Combinator seed accelerator program in late 2010, which helped it secure a $1.2 million funding round from angel investors shortly thereafter. By 2011, Optimizely became cash flow positive, and its growth continued with significant funding rounds, including $28 million in Series A funding in 2013 and $57 million in Series B funding in 2014, led by prominent venture capital firms like Andreessen Horowitz and Benchmark.
Optimizely CMS has successfully raised several rounds of funding, totaling over $150 million. Key funding rounds include:
The company’s valuation has seen fluctuations, especially following its acquisition by Episerver, but it remains a significant player in the digital experience space, serving over 10,000 businesses globally.

The company's philosophy emphasizes being "large enough to serve, small enough to care," reflecting its commitment to providing personalized service to clients.
