Thesauros

What Thesauros does

Thesauros is a privately held German real estate and infrastructure services group headquartered in Cologne, operating for more than 37 years across the full real-estate value chain. The group is structured as two parallel holding entities — Thesauros Immobilien Holding GmbH & Co. KG and Thesauros Capital Holding GmbH & Co. KG — beneath which sit seven specialized operating subsidiaries: Thesauros Finance AG (real estate consulting and structuring of Alternative Investment Funds), Thesauros Architektur AG (architecture, general planning, development), Thesauros Construction GmbH (general contracting and construction management), Thesauros Readiness GmbH (supply chain analysis and logistics real estate), Thesauros Law GmbH (private and public construction law), Thesauros Beteiligung GmbH (project participation holding), plus three project-specific property entities (Erste/Zweite/Dritte Liegenschaft GmbH & Co. KG). The group also owns Chreon GmbH. Technology is conventional professional-services infrastructure, including Windows 11 CAD environments; no proprietary software platform is disclosed.

The firm generates revenue through five interlocking streams: real estate development and project management fees, architecture and general contractor services, legal advisory, supply chain and logistics real estate consulting, and structured finance / asset management fees (including AIF fund management). Go-to-market is enterprise field sales combined with public procurement tender participation — the group maintains continuous 5-year pre-qualification in the German IHK AVPQ register. Pricing is bespoke and quote-based; no standard rate cards are published. Customer segments include entrepreneurs and business owners (primary), public-sector and government clients including the Bundesministerium der Verteidigung (primary), institutional investors and family offices, and educational institutions. Notable engagements include the MINT42 canteen at ALDI SÜD IT headquarters, the restoration of the Alte Synagoge Essen, the renovation of the Erich-Kästner-Gesamtschule in Essen, and the Crown mixed-use arena and leisure quarter under development in Bietigheim-Bissingen with a targeted 2026 opening.

Ownership is concentrated in the Michels family: Willi Michels serves as CEO, Simon Michels and Diane Michels sit on multiple executive boards, and David Michels holds management roles across the construction, architecture, and finance entities. The supervisory boards of the AG entities include Dr. Ulrich Wolters (former ALDI SÜD executive) as Chairman, plus Jürgen Fitschen and Hans-Jürgen Riegel on the Finance AG board. Distribution and marketing channels span direct enterprise sales, public tendering, an investor network for AIF products, LinkedIn, a company newsletter, the legal specialist publication 'THE Law Fachmagazin', trade fair participation (including digitalBAU in Cologne), and earned media coverage. No external institutional investors or PE backing have been disclosed.
