What Plan4 Software does
PLAN4 Software GmbH is a Freiburg, Germany-based PropTech company founded in 2018 that operates the GebäudeCheck SaaS platform, a vertical software solution for digital building condition assessment and renovation planning aimed primarily at German public property owners. The product enables municipal staff, church institutions, housing companies, and independent building experts (Sachverständige) to capture building data on-site via a tablet-optimized iOS/Android mobile app with offline mode, then produces structured cost estimates aligned to DIN 276, energy and CO2 analyses per DIN V 18599 and BEG standards, GAEB file exchange with downstream AVA tooling, and automated Word/Excel reporting. A 2025 add-on module, ENERGETISCH SANIEREN, extends the platform with simulation of renovation measure combinations targeting Effizienzhaus 40/55/70 classes, plus KfW/BEG subsidy identification. The product surface is rounded out by 3D surveying, pilot onboarding, and full-service assessment offerings delivered by PLAN4's in-house architects and engineers.
The company monetizes through a combination of recurring SaaS subscriptions (typically annual contracts with monthly or annual billing, including user seats and evaluation limits), professional services billed on time-and-materials or fixed-price terms, and a flexible 10er-Karte prepaid package that allows ten building evaluations within twelve months without long-term commitment. Go-to-market is sales-led and multi-channel: enterprise field sales targeting municipalities with regional reps (e.g., NRW territory), an inside-sales function for inbound lead qualification and smaller accounts, a partner/reseller channel anchored by a co-developed Hottgenroth Software AG bundle pairing HottCAD 3D measurement with GebäudeCheck, plus webinars, industry events (JIB, KOMMUNAL trade fair), and content marketing (blog, whitepapers, newsletter). Over 100 municipalities and church institutions are served and more than 1,000 municipal buildings have been assessed on the platform; the company holds GDPR-compliant delivery from German data centers and runs a 98% uptime SLA during German business hours.
PLAN4 closed a €4 million growth investment from Knight Capital alongside existing investors in January 2026, following earlier rounds backed by Aureus Partners, Bitstone Capital, and Sprengnetter, with capital explicitly earmarked for team expansion, nationwide German rollout of GebäudeCheck, and continued product development. Leadership consists of co-founder Managing Directors Thorsten Harig and Dr. Hendrik Seibel, with Matthias Mand serving as Prokurist and Sales Director and Tim Gläfer active in partner-facing roles. The company is privately held, headquartered at Güterhallenstraße 4, 79106 Freiburg, and operates exclusively in the German market.

Plan4 Software competitors and assessment
Company assessmentDirect peers
- Archilogic: Building digital twin and property data platform serving real estate professionals with 3D capture and portfolio analytics—closest direct peer to PLAN4's mobile capture and assessment workflow for property owners.
- PlanRadar: SaaS for construction and real estate documentation, defect management, and inspection—directly competes in mobile building assessment workflows and uses a similar B2B sales-led GTM into property professionals.
Broad incumbents
- Nevaris (AGS, Nemetschek-Gruppe): German-speaking construction and AVA software with DIN/GAEB compliance—overlaps in standards alignment and target market, but serves the broader construction lifecycle rather than specializing in building condition assessment.
- RIB Software: German construction and real estate software spanning AVA, BIM, and ERP—broader portfolio with overlapping standards calibration and an established enterprise footprint in German-speaking markets.
- Nemetschek Group: AEC software conglomerate with brands across BIM, FM, and CAD—a potential platform-level competitor in Germany that could assemble assessment functionality from existing portfolio pieces.
- Aareon: Dominant German housing-company software suite serving the same municipal and church-property buyer base—could extend building assessment features into its installed base of Wohnungswirtschaft customers.
- Autodesk Construction Cloud: BIM and construction project management cloud with overlapping workflows for building documentation, field capture, and assessment—at much broader scale and global reach.
Others
- Hottgenroth Software AG: 3D building measurement (HottCAD) and AVA software serving the German construction market—PLAN4's active channel partner and technological neighbor with overlapping customer base.
Emerging players
- VertiGIS: GIS-centric smart building and asset management software—overlapping digital twin and building data concepts, focused on infrastructure-heavy organizations with comparable spatial data angle.
- Matterport: 3D spatial capture platform for buildings—direct technology overlap on building data capture used by PLAN4 and Hottgenroth, though Matterport serves broader residential, insurance, and facilities use cases beyond German municipal assessment.
