Andy Florance

One of the more memorable ads during this year’s Super Bowl starred Dan Levy and Morgan Freeman on behalf of Homes.com. What kind of real estate company has cash for a 30-second spot with such actors during what’s usually the year’s most watched U.S. television program? 

Homes.com — which is exactly what it sounds like, a platform connecting homebuyers, sellers and agents — falls under the wide umbrella of the CoStar Group. That’s the company that Andy Florance famously founded in 1986 from his dorm room as a Princeton undergrad.

The rest of that umbrella covers a host of brands in the increasingly important commercial and residential real estate search and data universe. To rattle off a few: CoStar itself, commercial real estate marketplace Loopnet, rental site Apartments.com, 3D modeling firm Matterport, CRE exchange TenX, hospitality data cruncher STR and rural search engine Land.com. And, per that last one, around the time of that Super Bowl ad in February, CoStar acquired Ag-Analytics, a platform with the valuations of nearly 3 million land parcels, and added its functions to Land.com. 

It’s a juggernaut, for sure.

“CoStar remains a mission-critical tool for our clients across all segments,” Florance said on the company’s first-quarter earnings call last month. “Log-ins to CoStar were up 21 percent year-over-year, and our subscribers averaged 100 million activities each month, the highest level of activity in the past nine quarters. Our quarterly renewal rate remains strong at 92 percent.”

That same earnings call showcased $732 million in revenue in the first three months of 2025, a 12 percent annual gain and the 56th straight quarter of double-digit percentage revenue growth.

CoStar also spent part of 2024 finalizing its plans to relocate its headquarters this year from Washington, D.C., to Northern Virginia. The company reportedly spent $339 million on a 31-story Arlington property in February last year.
