Thesius

What Thesius does

Thesius is a German web platform that aggregates academic and early-career resources for students and connects them with companies and universities. Its core products include a thesis topic search (Themensuche), a survey promotion tool (Thesius Surveys) that uses a lottery/prize mechanic to recruit participants, a job board and company directory (Unternehmensübersicht), a community forum, citation tools (Zitieren) developed in cooperation with the writing workshop at Johannes Gutenberg-Universität Mainz, and an academic and career blog. The platform also operates the Recherche database, which Thesius describes as the only database aggregating all German dissertations together with current Bachelor and Master theses, complemented by indexing access via the Deutsche Nationalbibliothek.

The platform is built as a self-serve web application, with user accounts, profile-as-CV functionality, favorites, and an internal application workflow that routes student profiles to corporate contacts. Distribution runs through the thesius.de website, organic social (Facebook and Twitter), email newsletters, university referrals (notably Johannes Gutenberg-Universität Mainz), and content marketing via the academic blog and citation-style guides. Survey promotion is compatible with SoSci Survey (recommended tool, 10,000+ academic surveys per year), Unipark, and SurveyMonkey.

Commercial model is dual-sided: free for students across thesis search, survey promotion, dissertation database, and applications, with monetization concentrated on the corporate side through paid thesis topic postings, job listings, and survey lottery sponsorship (Jobify and StudentJob.ch partnerships also support the career content layer). The platform is legally operated by persona service AG & Co. KG, a German staffing and services company headquartered in Lüdenscheid that acts as data controller and parent; Thesius functions as a digital platform brand within that corporate parent's portfolio. The geographic footprint is Germany with Austria referenced in German-speaking reach, and there is no disclosed public listing, no venture funding rounds, and no disclosed revenue figure.
