What GemDat does

GemDat AG is a privately held Swiss software company founded in 1986 and headquartered at Bahnhofstrasse 6 in St. Gallen, specializing in cloud-hosted and on-premise software for the complete lifecycle of buildings and properties in Switzerland. The company develops a suite of integrated platforms spanning construction permit management (gemdat bau, cymo ebau), building insurance operations (gemdat versicherung, TOPAX), property tax assessment (gemdat bewertung, gemdat ggst), document management and archiving (gemdat dms & archiv built on d.velop documents as a Gold Partner), real estate portfolio management (immoledo), and mobile field applications (gemdat mobile versicherung). Its technology stack uses HTML5 web front-ends, cloud-native delivery from GemDat's own Swiss data center, mobile web apps, and APIs conforming to Swiss e-government standards (eCH-0211, ÖREB); a recent addition is the SQUARE Assist AI chatbot for construction law, co-developed with Squaretech GmbH.

GemDat monetizes primarily through annual cloud/SaaS subscriptions bundled with infrastructure, updates, and second-level support, supplemented by on-premise licenses for larger cantonal customers, paid consulting engagements (efficiency analyses, process design, change management), and recurring maintenance contracts. The company operates a hybrid go-to-market combining direct enterprise sales to cantonal governments, major cities, and building insurers with a 13-partner channel network of certified engineering and surveying firms (Emch+Berger, GEOAargau, GeoGR, GEOINFO, Ingesa, Sutter, CM Informatik) that resell and implement GemDat products to mid-sized municipalities. Demand generation centers on ERFA peer-exchange breakfast conferences across Aarau, Bern, St. Gallen, and Zürich, structured webinar series, detailed case-study content, and public procurement (Submission) processes.

At scale, GemDat's systems process over 30% of all Swiss construction permit applications in German-speaking Switzerland, manage 40% of all Swiss properties, serve 420 customers, and handle 1.3 million documents sent annually, with ~1,020 billion CHF in insured building capital under management. The customer base spans Swiss cantonal and municipal building authorities, tax administrations, public building insurers (with TOPAX deployed across 7 cantons), real estate managers, banks (e.g., Luzerner Kantonalbank), and the Liechtenstein government as its first international deployment. The company holds ISO 9001:2015 certification and is led by CEO Sandro Ferrarini with eight business-unit and functional heads.

Revenue model

1. Software Subscriptions (Cloud/SaaS): GemDat's primary revenue stream is annual subscription fees for cloud-hosted software products. All major products (gemdat bau, cymo ebau, gemdat versicherung, gemdat bewertung, TOPAX, immoledo) are available as cloud solutions. Customers receive ongoing updates, 2nd-level support, and infrastructure management as part of the subscription.
2. On-Premise Licenses: Some customers (especially larger cantonal governments) operate GemDat products on-premise. This generates one-time license fees plus ongoing maintenance and support contracts.
3. Consulting and Implementation Services: GemDat provides paid consulting engagements covering efficiency analyses, software evaluations, business process analysis, requirements gathering, project management, and change management. These are structured consulting engagements billed as professional services, often preceding or accompanying software implementations.
4. Ongoing Support and Maintenance: Annual support contracts (Level 2 support, bug fixes, regulatory updates) bundled with software subscriptions and license agreements. Dedicated helpdesk with product-specific email addresses and phone support.

Scale indicators8 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• CAS Software AG: German CRM and enterprise software vendor with deep penetration in German Mittelstand and DACH. Comparable as a DACH-focused vertical SaaS provider with similar size and regional depth to GemDat, though primarily serving different verticals (CRM/ERP) rather than government/insurance focus.
• msg Group: Large German enterprise software and consulting group (8,000+ employees) serving insurance, banking, automotive, and public sector. Provides msg.PIA (insurance core system) which GemDat integrates with via TOPAX for Aargauische Gebäudeversicherung, making it both a partner and an adjacent incumbent with broader resources in the insurance software market.
• SAP SE: Global enterprise software giant with SAP RE (Real Estate) and broader ERP modules that compete at the high end with GemDat's property valuation, building insurance, and document management workflows. GemDat integrates via d.velop archive link for SAP Solutions rather than directly competing — relationships are complementary, but SAP could expand deeper into Swiss government/insurance verticals.

Emerging players

• Wüest Partner: Swiss real estate data, analytics, and advisory firm with software products for property valuation and market analysis, employing 400+ specialists across Switzerland. Comparable as a Swiss player serving property valuation and tax assessment use cases with adjacent technology, though more focused on data/analytics than workflow software.
• Immomio GmbH: German PropTech providing rental property software with focus on tenant screening, digital leasing, and property management for landlords and property managers. Adjacent to GemDat's real estate management solutions (gemdat immobiliendossier, immoledo) though more focused on residential rental workflows and newer to market.

Direct peers

• Haufe Group: German provider of real estate, tax, and HR software solutions with strong presence in DACH, including Haufe-Lexware Real Estate and property valuation tools. Comparable to GemDat in delivering vertical SaaS for property-related workflows including valuation, tax assessment, and document management, though with broader portfolio across multiple verticals.
• GARAIO AG: Swiss software vendor specializing in real estate ERP and property management solutions for the Swiss market, headquartered in Winterthur. Closest direct peer to GemDat in Swiss vertical SaaS, serving similar mid-market property managers and real estate companies with comparable size, market focus, and Swiss-market depth.
• Innosolv AG: Swiss software vendor providing e-government and ERP solutions (NEST, BusinessPlus) for municipalities, with products in the building permit and public administration space. GemDat's gemdat bau integrates with Innosolv's NEST product (per GemDat's own integration roadmap), indicating both partnership and direct overlap in the Swiss e-government software market for building permit processing.
• Aareon AG: Germany's leading provider of real estate software and SaaS solutions, serving housing industry, property managers, and real estate companies across DACH with 1,000+ employees and tens of thousands of customers. Directly comparable to GemDat in vertical real estate software focus and SaaS delivery, though much larger and serving broader segments including social housing, commercial, and energy management.

Others

• Drees & Sommer: German real estate consulting and engineering firm with 4,000+ employees and software/technology components for building lifecycle, FM, and digital building operations. Adjacent rather than directly competing, though both serve the building and property ecosystem across DACH with software and consulting offerings.
