Empowering investors, brokers, owners, and occupiers with the data and analytics needed to succeed in France’s estimated €300 billion commercial real estate market

CoStar Group (NASDAQ:CSGP), an S&P 500 company and the global leader in real estate marketplaces, information, analytics and 3D digital twin technology today announces the official launch of the CoStar platform in France – bringing its commercial real estate intelligence platform to one of Europe’s largest markets. The launch builds on CoStar Group’s acquisitions of BureauxLocaux and Business Immo and significant investment in local proprietary research to create 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 can use a single platform to access curated property records, live availabilities, verified sale/lease comparables, exclusive industry news and real-time market analytics built from the ground up for the French market.

The launch was made possible by CoStar Group’s investment of more than $5 billion in proprietary data and technology over four decades to build a proprietary global database that is unmatched in the industry. Globally, the CoStar platform draws on:

9 million properties tracked
8 million commercial tenants and 2 million owners connected to properties
7 million lease activities and 5 million sales comparables
15,000 analytical reports covering markets and submarkets
Industry news articles linked directly to properties and people.

From launch in France, CoStar will deliver one of the most comprehensive commercial real estate datasets in France spanning office, logistics, and hospitality sectors across the country’s major metropolitan areas – including Greater Paris, Lyon, and Marseille. CoStar clients immediately benefit from more than 290,000 properties tracked, 385,000 commercial tenants, 90,000 availabilities, 75,000 lease activities and sales comparables, over 134 market and submarket analytical reports, and market-leading real estate news.

"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," said Andy Florance, Founder and CEO of CoStar Group. "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 France of CoStar Group: "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."
