The story
In 1998, in Copenhagen, Denmark, University of Copenhagen alumni Thomas Albert, Jakob Christensen, Peter Christensen, Ole Sas Thrane, and Michael Seifert founded Pentia A/S, a systems integration company that focused on implementing websites built on Microsoft technologies. At the time, building and managing websites required the expertise of a programmer or developer. Thrane and Christensen devised and patented a set of procedures for building and managing websites and turned their invention into a content management system product.
In 2001, Sitecore was spun off as a separate business entity that initially sold content management systems in the Danish market. However, the company has grown into a global provider of customer experience management software targeted primarily at corporate marketing departments and marketing service providers.
