ESTATIKA GmbH

What ESTATIKA GmbH does

ESTATIKA GmbH is a Münster-based engineering services firm founded in May 2019 that specializes in structural engineering (Tragwerksplanung) for the German real estate and solar markets, with a sharpened strategic focus on PV-Statik (photovoltaic structural engineering) since July 2025. The firm delivers structural feasibility assessments, certified structural proofs (Standsicherheitsnachweis, Unbedenklichkeitsbescheinigung), wind simulations, and load-reserve analysis for rooftop, ground-mounted, facade, and Agri-PV installations, leveraging CFD-based wind simulation (DLUBAL RWIND 3), 3D FEM modeling, and reverse engineering of existing buildings. Co-founded by Stefan Tiesmeyer (Commercial Director) and Rajeevan Sithamparanathan (Head of Structural Engineering), with Dr.-Ing. Christoph Ebbing joining in March 2021 and later becoming Managing Director, ESTATIKA employs 5 people, holds chamber registrations across four German states, and serves property owners, investors, PV/EPC companies, commercial and industrial property operators, and banks/energy consulting firms.

The company generates revenue on a project-based professional-services model, combining paid structural engineering deliverables with free initial Quickcheck assessments as a funnel mechanism, plus grant/funding advisory (Fördermittel) and the digital 3D-Gebäudecheck tool for portfolio-scale energy consulting. GTM is primarily sales-led via direct digital channels (website, Microsoft Bookings, WhatsApp Business, email, phone), augmented by event-driven outreach (EXPO REAL 2023, Münsteraner Immobilienforum, gif e.V. forums) and partner referrals (e.g., .bieker AG, Feldmann Architekten, IHK Nord Westfalen). The business operates without external funding and has accumulated 2,250+ completed projects across Germany and the EU, supported by a 4.80/5.00 average rating from 167 reviews.
