New Delhi: Whoop is engaged in a legal fight in the booming wearable health technology sector, where it is suing a much smaller competitor, Bevel. The lawsuit comes shortly after Whoop announced a $575 million funding round that pushed its valuation past $10 billion, which is raising questions about the manner in which the company is making decisions on how to compete in the market.
Whoop has been accused of focusing more on litigation than innovation; however, Bevel CEO and co-founder Grey Nguyen has publicly denied the allegations. In a video uploaded on X, Nguyen claimed that the suit is about fear on behalf of a significantly larger company, as opposed to intellectual property issues, so the case is seen as a battle between a large company and a team of startup engineers consisting of 20 individuals.
Lawsuit centers on design and feature similarities
Whoop filed a lawsuit against us, and this is our response.
TL;DW:
– June 2024: Whoop’s Corp Dev reached out wanting to “explore collaboration”
– 5 months later: cease and desist letter
– Their demands: disable dark mode (ours defaults to light mode), rename common words like… https://t.co/5tiN8ol3Fe— Bevel (@bevel_health) April 3, 2026
Whoop claims that Bevel duplicated major aspects of its app design, such as its overall look and feel, according to a 111-page complaint filed in March. The company asserts that such similarity may mislead the users into thinking that the two platforms are related. Gadgets and Wearables also report that the lawsuit also contains claims of copyright and patent violations.
Nguyen has strongly denied these claims. In his retort, he contended that most of the disputed features, including strain and recovery scores, are common in the fitness and health tracking sector. The notion that interface features such as dark mode are proprietary was also dismissed by him.
From potential partners to legal rivals
Nguyen also stated that the connection between the two companies did not start on a very different note. In June 2024, the Whop representatives are said to have contacted Bevel to discuss a possible partnership. During that communication, the employees at Whoop complimented Bevel on his performance and wellness in the athletic arena, indicating that the two might have a partnership opportunity.
However, Bevel was still in its early stages at the time, and Nguyen said the startup lacked the resources to pursue a meaningful collaboration. The situation would get out of hand months later, after Whoop received a cease-and-desist letter, and then it remained silent until Whoop finally brought the case to the federal court in Delaware.
Dispute over who came first
One of the most controversial issues in the case is the product development timeline. Whoop asserts Bevel has a similar app interface with theirs, especially the home screen and coach capabilities. Nguyen argues this, saying that Bevel launched its revamped interface first and Whoop followed with a similar design.
He also stressed that Bevel is not a producer of wearable devices and that the company is a component of a larger ecosystem, as opposed to a direct competitor. A viewpoint of that kind, he said, is what renders the suit all the more astonishing.
The case identifies the increasing tension in the competitive health tracking market, where design, data insights, and user experience are now important differentiators. What was initially seen as a possible partnership has now become a legal battle-of-the-wit over which firms secure and define innovation in this area.
To date, both parties are holding their ground, which preconditions a legal battle that will be closely monitored between a tech giant and a startup.
