Related Companies

Related Companies is a privately held, fully integrated real estate firm founded by Stephen Ross in 1972 as an affordable-housing developer and now active across luxury residential, affordable housing, retail, office, hospitality, data centers, and city-scale mixed-use development. Related is the developer of Hudson Yards in New York City, The Grand LA, Time Warner Center (now Deutsche Bank Center), The 78 in Chicago, and operates regional platforms including Related Beal, Related Midwest, Related California, Related Ross, and Related Argent in the UK. The firm owns and manages roughly 55,000 affordable and workforce housing units and has stated it has never converted a single affordable unit to market rate. Stephen Ross also owns a majority stake in Equinox Holdings (Equinox fitness clubs, Equinox Hotels, SoulCycle, Blink Fitness) and the Miami Dolphins / Hard Rock Stadium.

human only

Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.

Kin Score

API Evangelist profiles Related Companies the way a machine reads it — 18 machine-readable artifacts, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.

Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Related Companies scores 7.2/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.
