Theis Consult GmbH

What Theis Consult GmbH does

Theis Consult GmbH is a privately held German limited-liability consulting firm headquartered in Aachen, NRW, that has operated for over 30 years (founded 1994) as a full-service provider in mobility management. The firm delivers end-to-end project services — from concept and planning through construction supervision, commissioning, and public-relations support — to public-sector clients (municipalities, road administrations, and public authorities) and, to a lesser extent, private-sector clients across Germany, Austria, and Switzerland. Its service portfolio is organized around four pillars: traffic telematics (Verkehrstelematik), ITS system construction (ITS-Anlagenbau) including traffic control centers and guidance systems, future connected and autonomous mobility, and mobility-and-environment integration (cycling infrastructure, e-mobility charging concepts, alternative propulsion). Supporting services span professional project management and mobility marketing/Öffentlichkeitsarbeit. The company is a project-based, sales-led consultancy with pricing negotiated per engagement and no public pricing or SaaS-style recurring model disclosed.

The firm's technology stack centers on Intelligent Transportation Systems (ITS) combined with proprietary data and modeling assets. Notable components include Floating Car Data (FCD) collection and analysis, an Environmentally Sensitive Traffic Management (ESTM) model that fuses traffic and emissions data, an Air Quality Dispersion Model (AQDM), and AIAMOnexus — an integration platform built within the federal AIAMO research project to consolidate heterogeneous traffic, sensor, and environmental data. An AI-based anti-fingerprinting approach anonymizes mobility data to address GDPR-class privacy risks. Digital twins integrating ESTM and AQDM have been deployed in pilot regions Leipzig and Landau. The company is an active participant in standardization bodies (DIN, CEN, ISO, FGSV) and operates as a partner in the AIAMO consortium alongside Bosch, T-Systems, SWARCO, UFZ, and FKFS, with the program funded at 16.7 million euros by the Federal Ministry for Digital and Transport (BMDV).

Theis Consult generates revenue exclusively through professional services: consulting engagements, ITS planning and construction supervision, and project-related public-relations work. Customer concentration is skewed toward public-sector procurement in the DACH region, with no named enterprise logos disclosed and no disclosed revenue mix. The firm holds KRITIS critical-infrastructure expertise aligned with BSI IT-Grundschutz (DIN VDE V 0832-700) and in August 2025 obtained TREI certification authorizing direct grid connection, opening adjacent revenue in e-mobility and cable infrastructure. It also operates the wholly owned subsidiary brand aixzellent, which provides custom software development, IT consulting, and EU AI Act compliance advisory to SMEs. The company is closely held, led by Managing Director Christian Roszak, with no external venture or private-equity investment disclosed.
