Sinnogy Gmbh

What Sinnogy Gmbh does

Sinnogy GmbH is a privately held German engineering consultancy headquartered in Freiburg that specialises in planning, optimising and consulting on climate-neutral heating networks for the communal heat-supply market. The firm was founded by Managing Director Dr. Harald Schäffler and operates a 30-person team delivering strategy, concept development, funding management and specialist technical planning to municipalities (Kommunen), energy suppliers and municipal utilities (Energieversorger/Stadtwerke), and the real estate sector (Immobilienwirtschaft) across Germany. The company cites over 100 completed projects, including the Queichtalzentrum cold district heating network in Offenbach an der Queich and climate-neutral new developments such as Schlier's "Am Bergle" and Mönchweiler's "Kälberwaid III".

Sinnogy's offering combines proprietary consulting methodology with trademarked software tools. The EVEREST-Formel® is a phased roadmap used as the structural backbone for BEW-funded feasibility studies, while sinnoGIS® (GIS-based spatial planning) and fluidit® (thermo-hydraulic simulation) form the technical planning stack. A 2025 product expansion added a free, QGIS-based platform-independent digital twin solution and the KWP-Kompass tool that compresses municipal heat planning into a roughly three-day exercise. The Community Wärmewende practitioner platform, with over 800 members, is positioned as both a marketing channel and a peer-network engagement layer.

The revenue model is professional services: bespoke consulting and technical planning engagements, entered via a free 20-minute initial consultation. Distribution is direct enterprise sales, augmented by content marketing (blog, webinars, monthly newsletter), live events such as the Symposium Zukunft Wärme, and ecosystem partnerships (EnergieSüdwest, vilisto, GETEC, and a broader Partnernetzwerk). Pricing is not publicly disclosed. The company is founder-owned with no disclosed external funding rounds.
