What weyer gruppe does

weyer gruppe is a privately held, family-owned network of 13 specialized engineering and consulting companies headquartered in Düren, Germany, with 16 offices across Germany, Austria, Poland and Switzerland and over 200 full-time experts. Founded in 1976 as horst weyer und partner gmbh, the group delivers multi-disciplinary engineering and consulting services to industrial plant operators and investors, planners and manufacturers, and public-sector authorities in the chemicals, pharmaceutical, mineral oil, supply/disposal, biogas and government verticals, including plant safety (ATEX, HAZOP/PAAG, SIL), Owner's Engineering, CFD and process simulation, pipeline stress and pressure-surge calculation, permitting management, and certified Sachverständigenorganisation work under AwSV/WHG and emissions trading regulations.

Its core technology stack combines deep engineering domain expertise with a portfolio of proprietary software products: AITEZA (an AI/KI business solution for organizational knowledge management that consolidates documents and website content into AI-powered data rooms, developed by weyer data engineering gmbh), VFI/MFI (a centralized industrial-plant management system for permit-condition tracking), PAKO (project and account-assignment software for engineering firms), AIM (resident information management for public-sector procedures), and the PROBIOTEC objection-recording database (a topic-tree-based database with BaFin-compliant servers for managing public planning-permit objections).

The group's revenue model blends project-based professional services (engineering and consulting delivered across the 13 firms) with a growing recurring tail consisting of paid weyer akademie seminars and intensive webinars (priced €299-€700 per attendee, plus bespoke in-house trainings), e-learning subscriptions, and software licenses for AITEZA, VFI and PAKO. Go-to-market is predominantly direct enterprise and public-sector sales via the website, supported by a content-led and event-led demand-generation program (corporate blog, 20+ year quarterly newsletter, weyer spezial brochures, free Sprechstunden, and a recurring § 29a BImSchG Erfahrungsaustausch). Marquee clients include Evonik Fibres, MiRO Mineralölraffinerie Oberrhein, TOMRA Sorting, Dürr Systems and Kanzan Spezialpapiere, with multi-year relationships spanning over a decade at several accounts.
