SponsorUnited
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.
SponsorUnited publishes 86 API contracts indexed on the APIs.io network, including Admin Surface Context API, Agency API, Agency Services API, and 83 more. Tagged areas include Company, Sponsorship, Sports, Entertainment, and Marketing.
The SponsorUnited catalog on APIs.io includes 1 event-driven AsyncAPI specification.
SponsorUnited’s developer surface includes engineering blog, documentation, support, signup flow, changelog, and 19 more developer resources.

Kin Score
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| Gaming, Entertainment and Sports | undeclared | - | - | - |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
