Company Overview
About CoStar
CoStar Group is the leading provider of commercial real estate data, analytics, and marketplace platforms, founded in 1987 in Washington, D.C. by Andrew Florance. The company was built on the conviction that commercial real estate — one of the world's largest asset classes — was fundamentally underserved by reliable data, and that building a proprietary research infrastructure to collect, verify, and distribute property information would create a durable competitive moat. CoStar's core technology combines a massive field research organization with digital data collection tools to maintain the most comprehensive commercial real estate database in the world.
Business Model & Competitive Advantage
CoStar's product portfolio spans multiple platforms serving different segments of the real estate market: CoStar for commercial real estate professionals, LoopNet for commercial property marketing, Apartments.com for multifamily rental search, Homes.com for residential real estate, and Ten-X for online commercial property auctions. This multi-platform strategy positions CoStar Group as the data and marketplace layer across every major real estate segment. The company attracted more than 134 million unique monthly visitors across its networks in Q4 2024, demonstrating the scale of its audience reach.
Competitive Landscape 2025–2026
CoStar Group reported $2.74 billion in revenue for 2024, an 11% year-over-year increase, marking its 56th consecutive quarter of double-digit revenue growth — a remarkable consistency streak in enterprise SaaS. The company's combination of proprietary data assets, marketplace network effects, and expanding residential real estate ambitions gives it multiple growth vectors as it targets the vast residential brokerage market that dwarfs its existing commercial business.
