CoStar Group Launches CoStar Platform in France, Eyes €300bn Market

CoStar Group has officially launched its commercial real estate platform in France, bringing its data and analytics offering to a market it estimates at €300 billion.

The launch builds on CoStar's earlier acquisitions of BureauxLocaux and Business Immo, alongside what the company describes as a significant investment in local proprietary research. The result, CoStar says, is" one of the most comprehensive commercial property databases ever built for the French market."

For the first time, investors, brokers, owners, corporate occupiers and lenders in France will be able to use a single platform for curated property records, live availabilities, verified sale and lease comparables, industry news and real-time market analytics.

Globally, CoStar has invested more than $5 billion in proprietary data and technology over four decades. In France specifically, CoStar clients get access to more than 290,000 tracked properties, 385,000 commercial tenants, 90,000 availabilities, 75,000 lease activities and sales comparables, and 134 market and submarket reports, spanning office, logistics and hospitality across Greater Paris, Lyon and Marseille.

Andy Florance, founder and CEO at CoStar Group, said:

"France is one of the most important real estate markets in the world, and we are delighted to bring to France the same platform that has transformed how commercial real estate is transacted in the United States, the United Kingdom and Canada. French brokers, investors, owners and occupiers will now be able to source opportunities faster, underwrite more robustly and make decisions with greater confidence. Commercial real estate operates across borders, and CoStar's subscriber base of over 320,000 CRE professionals around the world will now find it easier to evaluate opportunities in France, while French CoStar subscribers will be able to access opportunities abroad."

Sandra Roumi, general manager for France at CoStar Group, added:

"French real estate is entering a new era. Our ambition is clear: to support the real estate ecosystem with the highest standards in data quality, transparency, and technology. CoStar Group is investing heavily to build, alongside the French market, a new generation of tools and services designed to support performance, confidence, and growth."

The France launch lands days after CoStar disclosed a roughly 30 per cent stake in Wikicasa, Italy's agent-backed portal, suggesting the group's European build-out is broadening beyond data licensing into equity stakes as well as acquisitions.

CoStar Group posted $3.2 billion in revenue in 2025, its 60th consecutive quarter of double-digit growth. The company, founded in 1986 and headquartered in Arlington, Virginia, now operates in more than 15 countries and employs over 1,500 researchers worldwide. Its brands include CoStar, LoopNet, Apartments.com, Homes.com, Domain, Matterport, STR, Ten-X and OnTheMarket.
