CoStar Group Founder and CEO Andy Florance Named to Commercial Observer Power 100

The list highlights 100 of the most influential figures in commercial real estate in 2023

Washington, D.C. — May 16, 2023 — Andy Florance, Founder and Chief Executive Officer of CoStar Group (NASDAQ: CGSP), a leading provider of online real estate marketplaces, information and analytics in the property markets, today was honored as one of Commercial Observer’s Power 100.

The list, published annually, recognizes the most impactful figures in the commercial real estate industry and highlights the companies and figures adapting and innovating in the rapidly evolving CRE space. Power 100 winners include founders, executives, visionaries and change-makers who are committed to propelling the CRE industry forward. Winners were selected for their ability to recognize where CRE trends are heading, synthesize available data, and prepare for headwinds that are shaping the industry.

Florance’s entry on the list nods to CoStar Group’s planned international growth, as well as the success the company has seen since bringing staff back into the office and focusing on in-person collaboration. This inclusion comes on the heels of continued growth for the company. Founded in 1986, CoStar Group has grown to over 5,600 employees in 14 countries. Florance has overseen CoStar Group’s continued growth, including positive financial results quarter-over-quarter in 2022 and 2023, despite a turbulent year for the CRE industry.

“Commercial Observer has long been a prominent voice in the commercial real estate industry, and it is a great honor to be named to the Power 100,” said Andy Florance, Founder and Chief Executive Officer of CoStar Group. “This award is a reflection of CoStar Group’s continued commitment to provide innovative products and services for discovering properties, insights and connections that enhance and support our clients’ business goals.”
