SponsorUnited is a sports and entertainment sponsorship intelligence platform, founded in 2018 and headquartered in Stamford, Connecticut. Its B2B SaaS product gives brands, rights holders (teams, leagues, venues and events), agencies and media companies a searchable dataset of marketing partnerships — the company reports 403,000+ brands, 2.2M+ tracked deals and 21.1M+ data points across sports, entertainment, media and talent — used to discover, evaluate, price, negotiate and activate sponsorships. The platform (SponsorUnited 4.0) layers AI features on that dataset, including the Surface AI analyst, a Proposal Evaluator, and SPND (Sponsorship Price of Negotiated Deals), a pricing-transparency product built on verified deal data. SponsorUnited runs a production REST API at api.sponsorunited.com whose OpenAPI 3.0 description is publicly served, but it publishes no developer portal, API reference or partner program around it; access is sold as a paid subscription with custom pricing and no self-serve sign-up.
