PERVAL

What PERVAL does

Perval operates a proprietary real estate transactions database and valuation platform for property professionals in France. The company aggregates over 25 million property sale references drawn directly from notary deeds, providing 100% coverage of recorded property sales in France (excluding Île-de-France) with a publication lag of approximately six weeks from deed signing. Data is qualified by 50 in-house experts using automated methods, spans 8 property types with up to 30 descriptive fields per record, and is updated weekly.

The platform is structured around three integrated components: a notary deed database (Base de données Perval), an automated valuation tool that produces price ranges from address and surface inputs, and a modular Value Opinion Report generator that outputs Word-format appraisal reports integrating Insee indices and cadastral data. Perval is operated as an exclusive resource by ADNOV, which serves as the parent corporate entity.

Perval generates revenue on a transactional basis through the sale of reference lists (over 70,000 purchased annually) and valuation reports to a base of more than 2,500 active professional clients per year, primarily notaries, licensed real estate experts, and real estate agents. Distribution is conducted through a self-serve web platform with authenticated client login, supplemented by a toll-free hotline and referral traffic from partner sites including immobilier.notaires.fr, immo-interactif.fr, and the notaires.fr directory. Pricing is quote-based rather than publicly disclosed, and the company is privately held with no external funding rounds reported.

Emerging players

• RealAdvisor: European property valuation and analytics platform serving real estate professionals and investors. Comparable to Perval in offering automated valuation tools, with a focus on emerging use cases such as portfolio analytics.

Direct peers

• Yanport: French real estate market intelligence platform offering transaction data, estimates, and analytics to real estate professionals across France. Comparable to Perval in both data product and customer base.
• Etymo: French proptech providing real estate market data, analytics, and automated valuation tools for professionals. Directly comparable to Perval in target market (real estate professionals) and offering (data-driven valuation).
• MeilleursAgents: Leading French real estate valuation platform (owned by Axel Springer) providing automated property price estimates and market analytics to consumers and professionals. Closest direct competitor to Perval in France for property valuation services, with a broader consumer-facing brand.
• PriceHubble: European B2B proptech providing property valuation, market analytics, and AI-driven insights to banks, insurers, and real estate professionals. Comparable to Perval in valuation methodology and professional customer base, though with broader European scope.

Broad incumbents

• Zillow: Largest US-based real estate data platform with the Zestimate automated valuation model. Comparable to Perval as a broad incumbent in real estate data and valuation, though Perval focuses exclusively on France and curated notary data.
• SeLoger: Major French real estate listings platform part of the AVIV Group (Axel Springer). Overlaps with Perval in serving French real estate professionals and houses data products that partially compete with Perval's valuation tools.

Regional players

• Bien'ici: French real estate search and valuation platform with features including price estimation. Comparable to Perval in operating within the French property market, though primarily consumer-facing rather than professional-focused.

Others

• DVF (Demandes de Valeurs Foncières): French government's open data platform published by Etalab providing raw property transaction data. Perval explicitly positions against DVF as more curated, faster, and richer — making DVF the closest free substitute and primary competitive alternative.
• LeBonCoin: Major French general classifieds platform with a real estate vertical that includes price estimation tools. Adjacent to Perval in the French real estate data ecosystem but primarily a consumer listings marketplace rather than a professional valuation tool.
