CoStar Group Expands European Footprint with Strategic Acquisition of Business Immo in France

CoStar Group, Inc. (NASDAQ: CSGP), a dominant player in online real estate marketplaces and information services, has strategically moved to strengthen its presence in Europe through the acquisition of Business Immo, France’s premier digital platform for commercial real estate news and intelligence.

Why This Deal Matters

The move is significant given France’s robust real estate investment landscape, with approximately €40 billion flowing into commercial property transactions annually. By bringing Business Immo under its umbrella, CoStar gains immediate access to one of Europe’s most critical markets and a well-established audience of real estate professionals.

About Business Immo: The Acquired Asset

Established in 2004, Business Immo has evolved into a dominant force in French commercial real estate media. The platform attracts over 300,000 unique monthly visitors—including brokers, investors, developers, and lenders—and boasts 2,000 corporate subscribers plus 100,000 social media followers. Beyond digital news content, Business Immo operates print magazines, educational programs, and industry conferences, positioning itself as a comprehensive information hub for the French CRE sector.

CoStar’s Expanding Global News Network

This acquisition extends CoStar’s already impressive international news operation. With over 235,000 subscribers globally and 19,000 articles published annually, CoStar operates one of the world’s largest real estate news networks spanning the United States, Canada, the United Kingdom, Germany, and the hospitality sector through Hotel News Now. The company’s journalism team recently earned eight accolades from the National Association of Real Estate Editors, reinforcing its credibility in the industry.

Strategic Rationale

Andrew C. Florance, CoStar’s Founder and CEO, emphasized that news and information are integral to driving platform engagement. “There is a close intersection between commercial real estate news and our marketplace platform,” he noted. The Business Immo leadership team, headed by Sandra Roumi, will maintain operational control while leveraging CoStar’s technology infrastructure and global resources.

The Broader Picture

The deal underscores CoStar’s commitment to international expansion and its belief that quality real estate information drives users to digital marketplaces. For Business Immo, joining a publicly-traded tech company with vast resources opens pathways for product innovation and market expansion across Europe.
