Disqus () is an American blog comment hosting service for web sites and online communities that use a networked platform. The company's platform includes various features, such as social integration, social networking, user profiles, spam and moderation tools, analytics, email notifications, and mobile commenting. It was founded in 2007 by Daniel Ha and Jason Yan as a Y Combinator startup. In 2011, Disqus ranked 2 in Quantcast's U.S. networks with 151 million monthly unique U.S. visits. Disqus was featured on CNN, The Daily Telegraph, and IGN, and about 750,000 blogs and web sites. On December 5, 2017, Disqus was acquired by Zeta Global. History Disqus was first developed in the summer of 2007 as a Y Combinator startup headed by Daniel Ha and Jason Yan, who were undergraduates at the University of California, Davis. Disqus was launched on October 30, 2007. In early 2011, Disqus raised $10 million in funding from North Bridge Venture Partners and Union Square Ventures. In March 2011, Disqus was used by 75% of websites which included a third-party commenting or discussion system. On December 5, 2017, Zeta Global announced that it had acquired Disqus for an undisclosed amount. In a blog post, Disqus stated that it plans to continue operations as normal. Business model Disqus operates on the ad-supported freemium financial model: the service is free to use for both commenters and small websites, but displays ads. Web sites can pay fees to hide ads and unlock additional features. In November 2010, Disqus began officially offering three add-on packages for websites: Starting July 2012, Disqus offered just two premium packages, the VIP package and a single-sign-on-only package, for $99/month. Starting in March 2013, Premium packages were phased out. On January 4, 2017, Disqus announced new premium packages rolling out in March 2017. A later blog post clarified that over 95% of sites using Disqus, primarily for personal blogs and non-commercial sites, will be unaffected by the new premium model. Functionality Language support Both the Disqus site and comment system were translated into more than sixty languages in 2011. With the introduction of the new Disqus in 2012, language support dropped to seven languages and even though Disqus accepts applications for new languages, only one has been added since bringing the current number of supported languages to eight . As of 2017, Disqus is translated in 36 languages including Spanish, French, Japanese, and Chinese using crowd-sourced
