What Sitepark does

Sitepark GmbH is a privately held German software firm founded in 1997 and headquartered in Münster, Germany, specializing in internet-presence and content-management solutions for municipal governments and public-administration entities. The company's flagship product is IES/InfoSite 6, a Java-based headless CMS purpose-built for large editorial teams managing websites with thousands of pages and developed in close coordination with municipal customers. Complementing the CMS is atoolo, an open-source PHP web framework that powers websites generated by IES and operates independently of the CMS and database for performance and security; the framework is being progressively released to the developer community.

The firm sells primarily through a direct, sales-led motion targeting German municipalities (Kommunen) and districts (Kreise), with a single contact line for consultation and concept design covering software requirements, content structures, hardware, and overall conception. Revenue is generated via subscription-style licensing and ongoing support of the IES/InfoSite 6 CMS, along with associated development services; pricing is quote-based and not publicly disclosed. Scale signals include approximately 9 million residents informed by municipalities using Sitepark software, 7,000 editors actively working in InfoSite, and roughly 25,000 code commits per year, indicating a meaningful installed base concentrated in a single vertical and geography.

The company is founder-led under Managing Director Thorsten Liebold, with a long-tenured engineering team including Head of Software Development Sebastian Dierksmeier (since 1998) and engineers Holger Veltrup (since 2000) and Patrick Jankowski (since 2008). Sitepark maintains strategic partnerships with UX specialist die firma, IT service provider kdvz Rhein-Erft-Rur for NRW municipalities, and creative agency Sandstein. The company is privately held with no disclosed external investors, parent company, or acquisition activity in the available data.
