Most people tracking their health today end up with scattered clues. Their smartwatch shows sleep duration. A fitness app logs steps. A nutrition app counts calories. Yet few tools help people understand how all of this fits together.
Bevel, a New York–based startup, believes that’s the missing piece in the shift toward proactive health. The company has raised a $10 million Series A from General Catalyst to scale its AI health companion, which unifies data from wearables and daily habits across sleep, fitness, and nutrition into personalized insights.
The investment follows a breakout year for the two-year-old health tech company.
Bevel says it has grown more than eightfold within the past year and now reaches over 100,000 daily active users, making it one of the fastest-growing health apps in the U.S. The company also adds that the average user opens the app eight times per day, and retention remains above 80% at 90 days, rare numbers in a category where people often churn after reaching a short-term fitness goal.
“We think of health as a continuous journey, not a phase,” said co-founder and CEO Grey Nguyen in an interview with TechCrunch. “Bevel meets you where you are, learns from your habits, and helps you make small changes that compound over time.”
But with numerous health companion brands, from Whoop to Oura to Eight Sleep, why does the world need another one?
According to co-founder and CTO Aditya Agarwal, many of these health apps rely on accompanying hardware devices that customers must buy and maintain. Because such devices can be pricey, there’s an opportunity to create a product that’s purely software-based, giving people the flexibility to use the wearables they already own.

“A $500 ring or band is out of reach for a lot of people,” said Agarwal. “We already generate so much valuable health data from our primary wearables and other everyday sources. We wanted to make something that was more accessible across a much larger set of people.” Bevel users pay $6 monthly or $50 annually.
Unlike typical wellness apps that focus on a single area such as steps, sleep, or nutrition, Bevel combines them into one experience. It integrates with Apple Watch and other popular wearables through Apple Health and directly syncs with continuous glucose monitors like Dexcom and Libre. Garmin and additional integrations are in development, the company said.
All this information feeds into Bevel Intelligence, the company’s core software, which helps analyze key information and adapt recommendations to each user, learning how their body responds to stress, movement, or nutrition.
Bevel’s story started with pain — literally.
Before starting the company in late 2023, Nguyen, who previously led products at Sam Altman–backed Campus, and co-founder Ben Yang, who worked on machine learning at Opendoor, were building stablecoin infrastructure for enterprises. The demanding nature of startup life meant Nguyen took little care of his health, developing chronic back pain that went undiagnosed for months despite using wearables and seeing doctors regularly.
“Nothing pointed out what was actually causing my back pain, not even my doctors, which is crazy, right?” he said. “That’s when this idea came up. Everyone’s life is so nuanced. There are so many small things you do that stack on each other and, over time, create a chronic condition.”
Nguyen says he began piecing together his health data, tracking sleep, nutrition, and steps, and realized that issues across these areas had compounded over time. Low mobility from sitting too long, sleep problems caused by his mattress setup, and sodium-heavy meals that increased inflammation all played a role.
Similarly, Agarwal, formerly CTO at Dropbox and an early engineer at Facebook, had gone through his own health overhaul after years of intense work left him burned out. What helped was logging his data manually, through spreadsheets and connected trackers, to rebuild his energy.
When he connected with Ben and Grey about what they were building with Bevel, he saw they had a similar vision and joined the team.
“We shared the same North Star, which is helping people become more intelligent about their own health,” said Agarwal, who is also a partner at South Park Commons. The venture capital firm, alongside General Catalyst, invested $4 million into Bevel earlier this year.
With fresh capital and no plans to venture into wearables, Bevel intends to grow its team and expand horizontally into more services and partnerships that make proactive health accessible.
“Bevel’s mission to democratize health through intelligence and design deeply resonates with us,” said Neeraj Arora, managing director at General Catalyst. “The level of engagement they’re seeing from users is remarkable, and it’s become part of people’s daily lives — not just another app. We’re excited to support this team as they build the future of personal health.”
