The Chirp Wheel is a simple back pain relief tool that hits all the right spots. Founder Tate Stock landed a deal with Lori Greiner on Shark Tank, but the agreement did not close after filming. Since then, Chirp has grown into a much larger pain-relief brand with a broader range of wellness products. In 2026, Chirp Wheel is estimated to be worth $50 million.
Tate Stock’s Background
Tate Stock grew up in Draper, Utah, and later studied economics at Brigham Young University. In his younger years, he also served as a missionary for The Church of Jesus Christ of Latter-day Saints in Suva, Fiji. Before building Chirp, Stock sold pest control door to door for three years.
The Birth of Chirp Wheel
Stock once visited his aunt’s house, where he saw a yoga wheel lying around. He searched for it online but couldn’t find one, so he decided to make his own. With $400, he bought PVC pipes and yoga mats to make a prototype, originally called Plexus Yoga.
The company was founded in 2015 and within two weeks, Tate made $12,000 in sales. After a year, he made an impressive $180,000. Healthy early sales helped him redesign the product and add a patented spinal canal feature, which helps hit crucial muscles.
The founder launched a Kickstarter campaign, raising $1.5 million from nearly 18,000 backers. In 2018, Chirp Wheel made $8 million and by 2022 it sold over one million units in total.
Update Since Shark Tank
Unfortunately, the deal with Lori didn’t close after the show as the company isn’t listed on her personal website. In an interview with BusinessInsider.com, Stock said the outcome was mutual, explaining that Chirp had already achieved many of the things Lori could have helped with, including QVC exposure.
The Chirp Well is now an FDA-registered medical device which helps it stand out against similar products. The company now sells a wider range of products through its official site, including Chirp Wheel XR, Chirp Wheel+, Halo, RPM, RPM Mini, and Contour.
Its products are also stocked through major retail channels (Amazon, Target, Best Buy, Walmart, and Dick’s Sporting Goods) and has grown into a much broader recovery and wellness brand. In January 2026, Business Insider reported that the company had generated more than $250 million in sales over the past 10 years.
On Amazon, the product has a review rating of 4.4 stars from over 20,100 users. The company is worth an estimated $50 million and has helped over 500,000 customers tackle back pain!
Chirp Wheel’s Shark Tank Pitch
The business continued to flourish in 2020 and had year-to-date sales of $12 million at the time of the pitch. He appeared on season 12, offering $900,000 for 2%. $45 million is the largest valuation in the show’s history!
Tate gave a brilliant pitch, his partner wore a bubble wrap outfit to demonstrate the practicality of the product. The Sharks loved it and the founder was forecasting sales of $40 million for 2021 with a profit of $12 million. However, Daymond John was suspicious that Tate just wanted the publicity.
A bidding war broke out among three Sharks. Kevin and Robert made offers that included a royalty. However, Lori Greiner won with her offer of 2.5% for $900,000 but wanted to be repaid within 18 months. Tate was hesitant about giving away 0.5% equity but eventually accepted the deal.
