What TGC Group does
TGC Group (legal entity TGC Luxembourg GmbH) is a privately held consulting and software firm founded in 2003 that specializes in the digitalization of the construction industry in the DACH region (Germany, Austria, Switzerland). The company is headquartered in Wecker, Luxembourg, with German offices in Koblenz, Rommersheim, and Mainz, and operates with approximately 40 employees under Managing Directors Thomas Gabel and Tim Becker. Its core product is LISA, a proprietary construction collaboration platform built on a React/Next.js frontend, PostgreSQL databases, and AWS infrastructure (Lambda, SQS, S3) that enables photo documentation with automatic order assignment, geo-tagged navigation, plan viewing with annotations, and order-based real-time messaging between site managers (Bauleiter) and foremen (Poliere). LISA is complemented by a Digital Construction File built on Microsoft 365 (SharePoint, Teams, OneDrive, Power Platform), DMS migration services (e.g., from DocuShare to SharePoint), a three-tier AI training program (KI-Programm) covering 50+ construction-specific use cases, strategy workshops, and needs analysis. LISA holds ISO/IEC 27001, 27017, 27018, 27701, 9001, 20000-1, and 22301 certifications obtained in 2025, with GDPR-compliant EU hosting.
TGC makes money through a blend of project-based consulting services (strategy workshops, needs assessment, M365 implementation, DMS migration), subscription-based LISA licensing, and tiered AI training engagements. Pricing is not publicly disclosed; engagements are quoted based on scope, users, and organizational needs. Go-to-market is enterprise-focused direct sales led by construction-experienced consultants targeting managing directors, digitalization managers, and site managers of construction firms across multiple trades (civil engineering, road construction, building, prefabricated housing, tile work). Marketing relies on a detailed German-language website, LinkedIn/Xing/Facebook presence, industry events, and customer referrals. The firm has been named TOP CONSULTANT in 2021, 2022, and 2023, and holds the FAIR COMPANY seal (2024) for employer practices.
The customer base includes 15+ named enterprise construction companies such as Reisch, J. Friedrich Storz Verkehrswegebau, Nibler Unternehmensgruppe, Adolf Lupp, Otto Wulff, Köster, Schwabenhaus, SAW, UVB, Sanders Tiefbau, Pittel Brausewetter, Kondor Wessels, and Bockhardt Bau. Microsoft is TGC's core technology partner for the M365 stack, while LISA is hosted on AWS. No external investors, parent company, or public listing have been disclosed; the firm is owned and operated by its founders and management team.

TGC Group competitors and assessment
Company assessmentOthers
Direct peers
- LetsBuild: European construction project management and site collaboration platform covering quality, safety, and progress workflows. Comparable product scope to LISA with overlapping customer base of general contractors and site managers across European markets.
- Capmo: German construction project management and site documentation SaaS serving builders and trades in the DACH region. Comparable vertical focus, comparable customer profile, and overlapping workflows in construction collaboration and progress tracking.
- PlanRadar: Austrian-headquartered SaaS platform for construction and real estate documentation, defect management, and site-to-office collaboration. Closest direct peer to TGC's LISA — same DACH origin, same target buyer (site managers and foremen), and overlapping feature set in photo documentation, plan markup, and task tracking.
- Fieldwire: Construction site management platform for task tracking, plan markup, and punch lists used by trades and general contractors. Direct overlap with LISA's site collaboration and photo documentation functionality.
- 123erfasst: German construction-focused mobile time, material, and progress tracking solution for trades and contractors. Strong DACH overlap with TGC's target customer and complementary workflows around site-to-office data capture.
Broad incumbents
- Thinkproject: European provider of construction and infrastructure project collaboration, BIM, and document management software. Larger, broader platform competitor addressing construction digitalization across the full project lifecycle, including DACH markets TGC serves.
- Procore Technologies: Global construction management platform covering project management, field collaboration, and financial workflows. While US-centric and enterprise-focused, it increasingly targets European mid-market contractors that overlap with TGC's customer base.
- iTWO (RIB Software): German-founded construction enterprise software for estimating, scheduling, BIM, and project management. Much larger incumbent in the same DACH construction-software category, addressing similar digitalization buyers as TGC.
Emerging players
- DocuWare: German DMS and document workflow vendor with partial overlap to TGC's Digitale Bauakte offering on SharePoint. Comparable in targeting German Mittelstand but less construction-specific; relevant as an alternative DMS stack TGC migrates customers from.
