OpenSponsorship is a two-sided sports sponsorship and influencer marketing marketplace that connects brands with a network of more than 25,000 professional athletes, teams, sports creators, and health and wellness influencers across 150+ sports. Brands pay a monthly subscription to search the roster, post campaigns, submit proposals, manage contracts, and track ROI, while athletes and their agents join for free with OpenSponsorship taking a commission on secured deals. The platform layers AI-based matching, social-content search, campaign management, and reporting on top of a managed service that handles matching, outreach, contracts, and reporting. OpenSponsorship exposes no public developer API at this time; this profile captures its public identity and web properties for the API Evangelist network.
