Brand was very patient and understanding of my busy schedule within completing post to social media. Also, they sent me another package of supplements when the originally one got lost.

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.

Chase did a great job for us and created a very engaging video when all we asked of was a picture - above and beyond!

I really do love these speakers and headphones, and will probably do another post with the headphones because of this!
The brand has been slow to respond to messages concerning refunding my money. I purchased the products myself from Amazon, left my reviews, and am now waiting to be reimbursed; however, the brand is slow to discuss aspects such as paying me back but was initially quick to respond to messages regarding my purchasing of their products. I'm still waiting for my money and to be sure that the brand fully refunds the amount I spent. If they take days to get in contact with or don't release the full amount I'll have to take this a step farther. I'm sure they'll fulfill their end. I just hope it doesn't take forever.
Our team really enjoyed working with Kasia. She did a great job.

I love the products and can feel the difference in my workouts!!
Fun and easy to work with. Would love to work with them again on a larger campaign!

Alex did not follow the proposal requirements and requested more money to complete the remaining deliverable (post an IG Story with the athlete in the video and provide us the raw video file.) The initial IG post by Alex was good, but the follow-through and demands for more money to complete the remaining actions seemed inappropriate.

This company has a great product and it was great working with them. Wasn’t expecting for them to send more than one product and some special bonuses so it was very nice
