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.

I really like their products. I just wish they tasted a tad better to take alone. Other than that I like the products and the positive effects they give

I really, really love your product. The only issue I have is that my stomach is pretty sensitive. I love all the flavors and the ability to dial it up and dial it down. I have noticed after enjoying a whole bottle (22 oz) my stomach will hurt. I am not sure if it is from air that I am taking in when sucking on the sip or an ingredient in the product. I would love to know your thoughts perhaps I am doing something incorrectly. Thanks!
