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.
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.
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 5.5/100 (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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

The organization behind the API
← All providers · Data indexed from github.com/api-evangelist/related-companies · machine-readable index on apis.io
This is an independent, third-party profile of Related Companies, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
