What Tcract does

TCract SAS is a France-based IT company founded in 2019 by Arnaud Ollivier, an engineer surveyor (ingénieur géomètre E.S.G.T.) with over seven years of 3D-capture experience, that develops and distributes the IZItopo software suite for professional topographers, surveying bureaus, and construction firms. The company is headquartered in Gillonnay (Isère), operates with 1-10 employees, and is organized as a French SAS with €20,000 capital social and no disclosed external funding. Its operating geography covers France, Switzerland, Norway, and other French-speaking markets, and it is one of a small number of authorized Bentley Systems resellers in France.

The IZItopo Suite is the core product and consists of three modules: IZItopo App, an Android mobile application for GNSS RTK topographic field data collection that supports Trimble Catalyst/DA2, TERIA, and TMM receivers in a hardware-agnostic manner; IZItopo Viewer, a cloud-based platform using Potree technology to render billions of point-cloud points and 360° panoramas in a browser for client review; and IZItopo Calcul, a photogrammetric processing module for generating point clouds and orthophotos. The suite is differentiated by real-time field-to-office synchronization, a free utility coordinate converter (convertisseur.izitopo.fr), and integration with the broader Bentley digital-twin stack (ContextCapture/iTwin Capture Modeler, iTwin Capture Manage & Extract/Orbit GT, MicroStation, LumenRT, OpenCities Planner). TCract also resells Trimble Catalyst DA2 and TERIA Pyx GNSS hardware plus RTK network subscriptions.

The business model blends software subscriptions (IZItopo App at cumulative volume pricing from €80 down to €24 per license/month; IZItopo Viewer at €49-79/month with a free 10GB/2-project tier and 20% annual discount), hardware sales and rental, RTK network subscriptions, Bentley software distribution, and professional training. Go-to-market is sales-led (request-a-demo model with 24-hour response commitment) complemented by product-led growth through the freemium Viewer tier, event-driven demand generation at trade shows such as Intergéo, partner co-marketing with Dronexperts, and SEO via free online utilities. Customer segments center on professional topographers and surveying bureaus as primary, with construction companies and land/infrastructure managers as secondary.

Broad incumbents

• Trimble Inc. Dominant GNSS hardware and surveying software incumbent whose Catalyst and DA2 receivers TCract resells. Trimble Access and Trimble Business Center compete directly with IZItopo App and the integrated topographic workflow.
• Leica Geosystems (Hexagon): Major surveying hardware and software provider (Captivate, Infinity) within Hexagon. Competes with TCract across field data collection and office processing for professional surveyors globally.
• Esri: GIS and mapping platform incumbent (ArcGIS). Comparable in the geospatial data layer for land and infrastructure managers, an adjacent secondary segment TCract also targets.
• Topcon Positioning Systems: Surveying and construction hardware/software incumbent offering MAGNET field and office suites. Competes with TCract's integrated field-to-office workflow for topographic and construction surveying customers.
• Bentley Systems: Infrastructure software provider whose ContextCapture, Orbit GT (iTwin Capture), and OpenCities products TCract resells. Bentley is both a partner and a broader competitor in reality capture and digital-twin workflows.

Direct peers

• DroneDeploy: Cloud platform for drone-based reality capture, mapping, and progress tracking. Competes with TCract's viewer-and-processing layer for surveying bureaus and construction firms doing aerial topographic work.
• Pix4D: Swiss-based photogrammetry software provider offering point cloud and orthomosaic processing. Comparable to TCract's IZItopo Calcul module and the broader reality-capture workflow for surveying professionals.

Emerging players

• Cintoo: Cloud platform for managing, sharing, and collaborating on reality capture / 3D point cloud data. Directly comparable to IZItopo Viewer's browser-based point cloud visualization and sharing value proposition.
• Propeller Aero: Drone-based surveying and earthworks platform focused on construction sites. Overlaps with TCract's drone-acquisition customer segment and cloud-based visualization approach.

Regional players

• Siteco: Italy-headquartered surveying software provider with strong European footprint in road and topographic design. Comparable as a regional European surveying software specialist targeting similar mid-market surveyor customers.
