ISL-KOCHER

What ISL-KOCHER does

ISL-KOCHER (legal name isl-kocher GmbH) is a privately held, family-owned German software company headquartered in Siegen that develops the isl-baustellenmanager, a modular Windows-based construction management suite built on C#/.NET Framework 4.8. The platform covers the full construction process chain from quantity takeoff in the bidding phase, through work preparation and 3D modeling, to REB- and GAEB-compliant construction billing and as-built documentation. It comprises 15+ specialized modules including easyGM (graphical quantity takeoff), easyDGM (earthwork calculation via digital terrain models), easyKM (canal/sewer quantities with ISYBAU export), easyAM3D (3D cross-sections for machine control), easyBA (excavation assistant), easyBAP (4D construction sequence planning), easyPW (point cloud processing), and GAEB365/Aufmaß365 (browser-based mobile measurement). The company serves civil engineering, road construction, earthworks, landscape construction, high-rise construction, and infrastructure projects in the DACH region, with notable enterprise customers including STRABAG, Echterhoff, and REIF.

The business model combines a freemium acquisition motion (six-month free trial with full service package), modular software licensing/subscriptions, and recurring training and consulting revenue. Go-to-market is sales-led with dedicated account managers supplemented by an extensive partner network (MTS Schrode, BRZ Deutschland, MWM Software, G&W Software, bps Software, vh software tools, Smart Site Solutions, 5D-Schmiede, Teamsware, and others), and reinforced by event presence at Intergeo, digitalBAU, BAU Munich, and joint roadshows. Distribution is tightly focused on the German-speaking market, with deep integration into established construction software ecosystems (BRZ7 ERP, G&W California.pro AVA, MWM-Libero, Topcon machine control) and alignment with mandated German data exchange standards (REB, GAEB, ISYBAU, CPI-XML, IFC, LandXML). ISL-KOCHER is privately funded, has no subsidiaries or M&A activity, and is led by founder Frank Kocher (Geschäftsführung) alongside second-generation co-manager Anna Carina Kocher.

Direct peers

• BRZ Deutschland: Nuremberg-based construction software specialist serving ~15,000 customers across Europe with ~600 employees. Both firms target the German construction mid-market with REB/GAEB-aligned workflows, and BRZ is both a technology integration partner (BRZ7 ERP) and a competitor in construction site management software.
• Nevaris Bausoftware: German construction ERP and building software provider (formerly Nemetschek Bausoftware), serving construction companies with end-to-end workflows. Direct competitor in the German construction software market, particularly for mid-sized contractors needing billing and quantity takeoff.
• G&W Software AG: Munich-based vendor of California.pro, an AVA/cost planning/billing platform used by 7,000+ companies. Strategic integration partner of ISL-KOCHER but also a competitor for cost calculation and construction billing workflows within the same customer base.
• bps Software GmbH: Founded in 1997, second-generation German construction software vendor offering complete digitalization solutions for civil engineering, road construction, earthworks, demolition, and engineering offices. Direct competitor for the same German Tiefbau customer segment with overlapping product scope.
• MTS Schrode AG: Specialist for automation, digitalization, and BIM in municipal road construction and civil engineering with 20+ years in market. Joint roadshow partner ('Durchgängig Digital im Tiefbau') and overlapping customer base, making it both an ally and adjacent competitor for civil engineering workflows.
• SOFTTECH GmbH: German vendor of construction software including AVA, BIM, and visualization tools for the German construction industry. Comparable in size and customer focus to ISL-KOCHER, with similar mid-market positioning and BIM/digitization value proposition.

Broad incumbents

• RIB Software (Schneider Electric): Major construction software platform (now part of Schneider Electric) with iTWO 4.0 ERP and BIM offerings serving large contractors globally. Operates far above ISL-KOCHER in scale and breadth, providing an integrated construction platform that competes at the high end of the German mid-market.
• Nemetschek Group: Global construction and AEC software conglomerate including Allplan, Graphisoft, Bluebeam, and Nevaris Bausoftware. Vastly larger scale and broader portfolio than ISL-KOCHER; competes via its Nemetschek/Nevaris brand stack for the same German construction customer base.
• Trimble: Global construction technology company offering Trimble Connect, site positioning, machine control, and BIM collaboration software. Provides machine control integration that ISL-KOCHER targets (Topcon integration mentioned), and broader construction lifecycle software that competes for enterprise budgets.
• Autodesk: Global AEC software leader including Revit, Civil 3D, and Autodesk Construction Cloud. Competes in the BIM and infrastructure space at the high end; ISL-KOCHER's IFC/LandXML compatibility supports interoperability but Autodesk's scale and R&D budget dwarf niche specialists.
