Each review is submitted by a brand, athlete, team or event to rate their deal on OpenSponsorship. All reviews are verified and tied to completed sponsorship deals.
OpenSponsorship connects brands with athletes, teams, and events for sponsorship and sports marketing campaigns. Once a collaboration is marked complete, both sides are invited to share feedback on communication, timelines, expectations, and deliverables. That means the ratings here reflect real outcomes from negotiated deals—not anonymous posts or incentivized testimonials. Transparent reviews help marketers compare talent and negotiate with confidence while giving athletes clearer expectations about partnering with reputable brands. Each entry on this page is tied to a verified, closed deal inside the platform's workflows. Taken together they show how sponsorship engagements perform at scale—from small product seeding kits to multimonth ambassador programs—with an overall average of 4.9/5 across 6,367 reviews submitted by brands and athletes.
Bill was wonderful to work with—easy going yet very efficient at replying to all messages and coordinating meeting times. Bill went above and beyond to create amazing content for our brand and help us drive results. In person he was warm and cooperative and we would definitely recommend him as a brand ambassador to any brand! Thank you Bill.

It was great working with Ultra Ankle! Kristi was very professional and responded very quickly to any questions that I might have had. Ultra Ankle is a great product that I am still promoting to those I coach as well as those I play with and against. I look forward to working with Kristi and Ultra Ankle in the future!

Don
She gave us a good post, but deleted the post after 2 weeks, and did not respond to our message asking why she took down the content. In the contract it said she had to leave it up for 12 months
Process was great, enjoyed working with him, would have preferred more personality in the content.
Great company to work with!
