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.

Great. I love medicileaf. The product is amazing. I am an older athlete that suffers from joint and muscle pain soreness. Medicileaf CBD product definitely work. I also felt welcomed to the company and feel like part of the team. Cant wait for future projects with medicileaf.

I love the IM-21 Brand. The product is awesome. As an older athlete, I do suffer from aches and pains that sometimes limit my athletic ability. IM-21 gave me energy plus sped up my recovery. I do want to continue to work with IM-21 and Mike Tyson in the future. I feel like this product can and will turn my into one of the top Heavyweight Calisthenics athletes in the world. I definitely stand behind this product. I look forward to future projects with IM-21.
