The company follows a sales-led, professional services model targeting municipalities and public sector clients in Germany. Revenue is generated through quote-based project consulting engagements structured as multi-year contracts, with a dedicated project manager serving as single point of contact throughout the project lifecycle. Notable technical capability includes advanced fourth-stage wastewater treatment design capable of removing over 80% of trace substances and 90% of microplastics from effluent. The firm holds VgV-QMS certification qualifying it for participation in regulated German public sector procurement processes for engineering services. Distribution is direct, with no channel partner or reseller model, and the company maintains regional office locations to serve clients across multiple German markets.

The firm is founder-owned (Horst Unger), with no disclosed parent company, external investment, or institutional ownership.
