What Stonal does

Stonal is a French SaaS proptech company founded in 2017 and headquartered in Paris (with a secondary office in Toulouse) that provides a cloud-native building data management platform for real estate owners, managers, and operators. The platform centralizes fragmented technical, financial, legal, and environmental data across building portfolios into a single source of truth, and integrates natively with major French property management ERPs (PIH, PRH, Ulis, Tegia, Ikos), Autodesk Revit (via a dedicated add-in), buildingSMART standards, BIM&CO, AWS infrastructure, and Thales S3NS sovereign cloud. A proprietary 4,400-component technical dictionary structures and normalizes building equipment and material data across all client portfolios, serving as the foundation for AI-driven modules including StonalGPT (a generative AI conversational assistant for property data queries, launched May 2024), SmartDoc (AI document classification and extraction), and a Python-exposed REST API.

The company serves primarily social housing operators and public-sector institutional owners in France — including Paris Habitat, CDC Habitat, 3F Action Logement, OPH31, Université Paris-Saclay, and Cergy Paris Université — alongside tertiary real estate owners, with a stated footprint of 130+ clients managing more than 200 million square meters and 1.9 million social housing units. The revenue model is annual SaaS subscription priced on portfolio size and managed square meters, supplemented by professional services for implementation and data migration; pricing is quote-based and not publicly disclosed. Distribution combines a direct enterprise field-sales motion targeting large public-sector accounts with a flagship channel partnership with Aareon, a European real estate software leader that also invested up to €100 million in May 2024 (one of the largest AI proptech rounds in Europe), bringing total capital raised to approximately €120 million and positioning Stonal for expansion into the Netherlands, Germany, and beyond. Stonal acquired La Place de l'Immobilier in November 2023, reported group revenue of nearly €20 million in early 2024, achieved profitability in late 2023, and has publicly targeted €100 million in revenue by 2027.

Broad incumbents

• Aareon: Aareon is the leading European provider of real estate ERP software (housing and property management). It is both Stonal's strategic investor and channel partner, and the closest comparable in terms of target customer (European housing operators), even though Aareon competes at the ERP layer while Stonal operates the data layer above it.
• Yardi Systems: Yardi is a major global SaaS suite for commercial and residential real estate operators, covering property management, accounting, and CRM. It overlaps with Stonal in serving large multi-asset property owners and increasingly in data and analytics, though it is a much broader platform with no BIM-first focus.
• RealPage: RealPage is a large US-listed SaaS provider of property management, accounting, and AI-driven analytics for multifamily and commercial real estate. It competes with Stonal at the asset-data and analytics layer for large residential and commercial portfolios, primarily in North America.
• Trimble (Real Estate & Facilities): Trimble provides BIM, facility management, and real estate software (e.g., Trimble View, Manhattan, AiM) targeting owners, occupiers, and operators of complex building portfolios. It competes with Stonal's BIM-to-operations positioning and targets similar large institutional clients.
• Autodesk Construction Cloud: Autodesk's construction and BIM portfolio (Revit, BIM 360 / ACC) is the upstream source of BIM data that Stonal's Revit add-in ingests. While focused on design and construction rather than operations, Autodesk is moving downstream into building operations and competes for some of the same asset data layer.
• Salesforce (Real Estate Cloud / AppExchange): Salesforce provides CRM and industry clouds (including real estate) used by large property owners and asset managers for tenant and customer data. It is a comparable in horizontal SaaS reach into real estate, particularly for multi-stakeholder collaboration and CRM-style data on portfolios.

Direct peers

• BuildingMinds: BuildingMinds is a European proptech offering a digital building data platform for commercial real estate owners and operators, centralizing building documentation and ESG/energy data. It is the most direct comparable to Stonal in product scope, with similar focus on structured building data and ESG compliance.
• Spacewell (MCS Solutions): Spacewell (formerly MCS Solutions) offers IWMS and CAFM software for facility and real estate management, including BIM-driven building data for large public and corporate portfolios. It is one of the most direct European competitors to Stonal in serving social housing, public institutions, and corporate occupiers.

Emerging players

• PlanRadar: PlanRadar is a European SaaS platform for construction and real estate documentation, defect management, and field reporting. It overlaps with Stonal's mobile-first field data capture and document collaboration use cases, particularly for social housing and asset management workflows.
• Archilyse: Archilyse is a data-driven real estate analytics platform that quantifies location, layout, and asset quality for property valuation and investment. It is comparable to Stonal's analytical layer for building performance, though narrower in scope (analytics) and primarily DACH-focused.
