This was such a fun campaign to work on. They let me be me and create content that is relatable to my audience which I fully appreciate. Communication was a breeze. Would definitely enjoy working with Qunol again in the future.

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.
