Compass
Compass is a New York City headquartered, tech-enabled residential real estate brokerage founded in 2012 by Robert Reffkin and Ori Allon. The company operates the largest residential real estate brokerage in the United States by sales volume, supporting roughly 36,890 agents and $267 billion in gross transaction value across approximately 250,360 transactions in fiscal year 2025, on $6.96 billion in revenue. Compass builds and operates a proprietary, end-to-end agent platform — an integrated cloud-based suite spanning CRM, marketing center, transaction management, listings, market analytics, the Compass One client dashboard, Compass Lens, AI-powered comparative market analysis, AI-generated video, virtual agent services, and a voice-activated AI assistant — custom-built for residential brokerage workflows. The company has invested over $100 million per year in technology and runs a 500+ person Product and Engineering organization, with engineering hubs that have included Seattle. Compass completed its merger with Anywhere Real Estate on January 9, 2026, combining two of the largest residential brokerage operators in the United States. The Compass platform is internal-facing: it is offered as the operating system for Compass agents and their clients, not as a developer product. There is no public REST API, OpenAPI specification, SDK, or third-party developer portal for the Compass real estate platform; the company's GitHub presence at github.com/urbancompass publishes a handful of internal-tooling open source projects (e.g. Snail, Mussel, hnvm, bazel-toolchain) rather than product APIs.
Compass is profiled on the APIs.io network. Tagged areas include Real Estate, Residential Real Estate, Brokerage, PropTech, and Real Estate Platform.
Compass’ developer surface includes engineering blog, academy / training, GitHub presence, YouTube channel, and 21 more developer resources.
