About

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.\n\nCoStar 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.
