SocialEngine

SocialEngine helps people and brands build vibrant, customizable online communities. Launched in 2007, there are now 10,000 customers of social websites powered by the SocialEngine platform, resulting in millions of end-users. The company currently has two platforms: SocialEngine Cloud and SocialEngine PHP. SocialEngine PHP gives you a simple, unbranded network that you can customize in any way. You’ll have the freedom to maintain fine-grained control over all aspects of your site and content. No “powered-by” branding.
