What tetraeder.com does

tetraeder.com gmbh is a German software company headquartered in Dortmund that builds SaaS platforms for formal municipal public-participation procedures, primarily under German planning law (BauGB). It operates as part of tetraeder.group, a diversified German group active in renewable energy, technology, and sustainability.

The company's product suite centers on PB (Planungsinformations- und Beteiligungsserver), a planning-information and participation server used to publish formal planning procedures, collect stakeholder statements, and coordinate public consultation, supported by PIA for interactive statement coordination, INKA for interactive map-based participation, and INKAstepbystep for structured step-by-step surveys. The platforms integrate with mandated German data standards such as XPLANUNG/XPLANKML and BIL Leitungsauskunft, and incorporate OpenAI-powered features for automated reporting, natural-language querying, and AI-supported statement optimization. A joint Dialogzentrale offering is delivered in partnership with zebralog.

The business model is enterprise SaaS sold directly to German municipalities, public authorities, and (more recently) private planning consultancies, on annual subscription contracts with custom enterprise pricing and dedicated sales consultants. The company reports 33+ employees, 250+ municipal and planning-office customers, and 3,800+ participation procedures run annually, and is expanding into adjacent verticals such as Kommunale Wärmeplanung.

Product overview

tetraeder.com offers a portfolio of four distinct digital participation and planning management products designed for German municipalities, public authorities, planning offices, and Träger öffentlicher Belange (public interest carriers). The core product is the Planungsinformations- und Beteiligungsserver (PB), a comprehensive planning information and participation server that manages the complete lifecycle of urban planning procedures, from document management through citizen participation to statement collection and archiving. PIA (Plattform zur interaktiven Abstimmung von Stellungnahmen) complements the PB by providing an interactive coordination platform for statements, enabling parallel processing by multiple departments. INKA (Interaktive Kartenanwendungen) delivers map-based citizen participation tools for spatial feedback collection, while INKAstepbystep (INKAsbs) provides step-by-step survey functionality with AI-powered analysis (via OpenAI) for detailed data collection. Together, these products cover the full spectrum of digital participation and planning management needs for German public administration.
