Episerver

Leading European-origin enterprise DXP vendor with strong presence in Nordic, UK, and North American markets before rebranding to Optimizely

Episerver was a Stockholm-founded digital experience platform company that grew to become one of the most recognized names in enterprise content management and digital commerce. Originally established as a CMS vendor, Episerver expanded its platform over the decades to encompass content management, e-commerce, personalization, and digital marketing tools, serving mid-market and enterprise customers across industries including retail, financial services, healthcare, and manufacturing. The company built a strong presence particularly in the Nordic region and the United Kingdom before expanding aggressively into North America. In 2021, Episerver completed a transformative merger with Optimizely, the well-known A/B testing and experimentation platform, and subsequently rebranded the entire combined entity under the Optimizely name. This move was backed by private equity firm Insight Partners and represented a strategic pivot to position the combined company as a comprehensive 'digital experience optimization' platform. The Episerver brand was retired as part of this transition, with all products, customer accounts, and go-to-market efforts consolidated under the Optimizely umbrella. During its operational years, Episerver competed directly with Adobe Experience Manager, Sitecore, Kentico, and other enterprise DXP vendors. Its platform was known for its developer-friendly .NET-based architecture, strong partner ecosystem, and relatively accessible pricing compared to larger competitors. The Episerver brand no longer exists as a distinct entity, but its technology and customer base live on within the current Optimizely platform.
