What skilltree does

skilltree Studios GmbH, operating under the brand 'skilltree', is a privately held German game development company headquartered in Trier (Schlesienstr. 2) and registered as a private limited company (GmbH) at the commercial register of Wittlich under number B 44591. The company positions itself as a 'technology transfer' studio that applies serious-games and gamification methods to non-entertainment sectors, with three named executive leaders — CTO Prof. Dr. Christof Rezk-Salama, CCO Prof. Dr. Linda Breitlauch, and COO Michael Jadischke — operating without any disclosed external investors or parent company.

The company's core product portfolio comprises two proprietary platforms. First, the skillpolis ecosystem, which consists of a Digital City Builder that procedurally generates 3D digital twins from OpenStreetMap data, a skillpolis Architect tool for authoring generic construction blueprints via branching construction trees, and a Smart City Simulation Game funded by the German Federal Ministry of Transport and Digital Infrastructure (BMVI) for citizen participation in urban planning. Second, the Skilltree eLearning System (SES), a web-based, LMS-compatible platform for delivering interactive, gamified learning modules built on didactic principles. Beyond these platforms, skilltree delivers project-based custom serious games, MOOCs, gamified simulations, and interactive visualizations to clients including Stadtwerke Trier, WasserWissensWerk Rheinland-Pfalz, ZIRP, ZSL Baden-Württemberg, BWIM, Unterworlds, Lodomo, and a DAX-listed international insurance group.

Skilltree's revenue model is hybrid: (1) professional-services revenue from quote-based custom project development for enterprise, government, and educational organizations, and (2) subscription/recurring revenue from SES platform licensing. GTM is sales-led via direct outreach and partnership-driven project engagements, supported by content marketing through a company blog and an active social presence across Twitter/X, Facebook, Instagram, LinkedIn, and YouTube. Marketing channels also include industry events such as gamescom/devcom and innovation programs like Innovate 2030. The company reports 11-50 employees and operates primarily in the DACH region, with the UN Global Compact membership (since January 2021) providing additional positioning around the UN Sustainable Development Goals.
