Venn is a multifamily resident-experience operating system for owner-operators of rental housing. Founded in 2016 and co-headquartered in New York and Tel Aviv, it merges a resident-facing mobile app, an operator dashboard and a single data layer over the resident lifecycle — leasing, onboarding, living, renewals, maintenance, payments, community programming and an AI concierge — synced with the property management system of record (Yardi, RealPage, Entrata, AppFolio). Venn runs an unversioned Apollo Federation GraphQL API at api.venn.city with anonymous introspection enabled, 320 query fields and 357 mutation fields across 468 object types, authenticated with AWS Cognito bearer tokens. It publishes no developer portal, API reference, OpenAPI or pricing; the contract is discoverable but the data and the docs are not public.
