Episerver is a global software company offering web content management (WCM) (or CMS), digital commerce, and digital marketing, through the Episerver Digital Experience Cloud software platform. Episerver also offers personalization through Peerius, a company acquired in August 2016 and which is now fully integrated into Episerver Digital Experience Cloud.[1]


Episerver was founded in 1994 in Stockholm, Sweden, by Mikael Runhem. Then known as Elektropost Stockholm AB, the company focused on internet-based electronic mail. Elektropost Stockholm AB expanded to provide technology for building websites and introduced the first version of the EPiServer CMS platform in 1997.[2]

In 2002, the first version of EPiServer CMS that was based on Microsoft’s .NET Framework, EPiServer CMS 4.0, was launched. In 2006, Mikael Runhem changed the company’s name to EPiServer AB. In 2007, the second .NET-based version of EPiServer CMS was launched, version 5.[citation needed]

In 2010, the company was owned by a group of investors, including Amadeus Capital, Martin Bjäringer, Monterro Holdings, Northzone Ventures, Mikael Runhem and family and employees. In November 2010, this group sold the company to IK Investment Partners.[3][self-published source?]

In December 2014, IK Investment Partners sold Episerver to Accel-KKR, a technology-focused private equity investment firm.[4][5] Accel-KKR had also recently purchased Ektron, a Nashua, New Hampshire-based CMS company. In January 2015, Episerver and Ektron merged.[6][7] Two former executives from KANA Software, CEO Mark Duffell and CMO James Norwood, were appointed President and CEO and Executive Vice President Strategy and CMO of Episerver, respectively. Martin Henricson, CEO of the former Episerver business assumed the role of Executive Chairman for the merged entity.[citation needed]

The company combined its software into the Episerver Digital Experience Cloud,[8] and in June 2015, Episerver launched the first major release of its platform following the Ektron merger.[9] In November 2015, the company rebranded itself, changing EPiServer to Episerver, and including the shortened name “Epi”.[10]

In August 2016, Episerver acquired Peerius, a London UK-based commerce personalization company. The brand now is fully integrated as EpiPersonalization into the Episerver Platform. Former Peerius CEO Roger Brown left the company.

In September 2018, Episerver was acquired by Insight Venture Partners for $1.16 billion.

In December 2019, Alexander Atzberger, former President of Customer Experience at SAP, joined Episerver as the company's new CEO.[11]
