Bevel raises $10M for AI that unifies health tracking without expensive hardware

Bevel, a New York-based health tech startup, has raised $10 million in Series A funding from General Catalyst for its AI health companion that unifies data from wearables and daily habits into personalized insights. The investment comes after a breakout year that saw the company grow more than eightfold and reach over 100,000 daily active users, positioning it as one of the fastest-growing health apps in the U.S.

What you should know: Bevel differentiates itself by being purely software-based, allowing users to leverage existing wearables rather than requiring expensive proprietary hardware.

• The app costs $6 monthly or $50 annually and integrates with Apple Watch and other popular wearables through Apple Health, plus continuous glucose monitors like Dexcom and Libre.
• Users open the app an average of eight times per day, with retention remaining above 80% at 90 days—rare numbers in a category where people often churn after reaching short-term fitness goals.
• Unlike typical wellness apps that focus on single areas like steps or sleep, Bevel combines sleep, fitness, and nutrition data into one unified experience.

The big picture: The health tracking market has become fragmented, with most people using multiple apps and devices that don’t communicate with each other effectively.

• “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,” the company explained.
• Bevel Intelligence, the company’s core software, analyzes this combined information and adapts recommendations to each user, learning how their body responds to stress, movement, or nutrition.

Why this matters: The startup is targeting a significant accessibility gap in the health tech market where premium devices can cost hundreds of dollars.

• “A $500 ring or band is out of reach for a lot of people,” said co-founder and CTO Aditya Agarwal, formerly CTO at Dropbox and an early Facebook engineer. “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.”

The founding story: Bevel emerged from the co-founders’ personal health struggles while building their previous startup.

• CEO Grey Nguyen, who previously led products at Sam Altman–backed Campus, developed chronic back pain that went undiagnosed for months despite using wearables and seeing doctors regularly, leading him to manually piece together health data across sleep, nutrition, and activity.
• CTO Aditya Agarwal had similarly rebuilt his energy through manual data logging after experiencing burnout from intense work.
• “Nothing pointed out what was actually causing my back pain, not even my doctors, which is crazy, right?” Nguyen said. “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.”

What they’re saying: The team emphasizes health as an ongoing journey rather than a temporary phase.

• “We think of health as a continuous journey, not a phase,” said co-founder and CEO Grey Nguyen. “Bevel meets you where you are, learns from your habits, and helps you make small changes that compound over time.”
• “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, a venture capital firm.

What’s next: With the fresh capital, Bevel plans to expand its team and grow horizontally into more services and partnerships without venturing into hardware manufacturing.

• The company is developing additional integrations with Garmin and other wearable platforms.
• “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.”
