Corporate Team

Michael Seifert, CEO

Michael started coding at age 11, and started his first IT company at age 15. Before (and during) college he was one of the principal developers of DikuMUD, an online multiplayer computer game serving millions of users, that was a predecessor to today’s massive role-playing video games such as “World of Warcraft”.

He completed his Master’s Degree in Computer Science and Human Computer Interaction (Copenhagen University) and went on to pursue advanced technical work with several Silicon Valley entrepreneurial companies in the U.S.

Michael was President of a successful multimillion dollar custom software development company for three years. He then envisioned the need for a Microsoft-centric system for creating and managing websites that could take the online experience far beyond the then present technology. In 2001 Michael, along with four fellow internet zealots, all well respected for their technical expertise, established Sitecore as a legal business entity. They introduced a product with functionality and appeal that was completely disruptive in the market, and which has evolved to be a market leader today. These five continue to be key contributors to the company, with Michael leading the business as CEO.

Michael is responsible for managing the global strategy, finance and operations for Sitecore, and has led our record-setting revenue growth and award-winning product direction.
