Bevel raises $10M Series A from General Catalyst for its AI health companion

Most people who monitor their health these days come with scattered clues. Their smartwatch shows sleep duration. A fitness app records steps. A nutrition app counts calories. Yet few tools help people understand how it all works.

Slanted sidea New York-based startup, believes this is the missing piece in the shift to proactive health. The company has raised a $10 million Series A from General Catalyst to scale its AI health partner, 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 in the past year and now reaches more than 100,000 daily active users, making it one of the fastest-growing health apps in the US. The company also adds that the average user opens the app eight times a day and retention remains above 80% after 90 days, rare numbers in a category where people often lose weight after meeting a short-term fitness goal.

“We view health as a continuous journey, not a phase,” said co-founder and CEO Gray Nguyen in an interview with TechCrunch. “Bevel meets you where you are, learns from your habits and helps you make small changes that add up over time.”

But why does the world, with countless health product brands from Whoop to Oura to Eight Sleep, need another one?

According to co-founder and CTO Aditya AgarwalMany of these health apps rely on associated hardware devices that customers must purchase and maintain. Because such devices can be pricey, there is an opportunity to create a product that is purely software-based, giving people the flexibility to use the wearables they already own.

“A $500 ring or band is out of reach for many people,” says Agarwal. “We already generate so much valuable health data from our primary wearables and other everyday sources. We wanted to create something that was more accessible to a much wider group of people.” Bevel users pay $6 per month or $50 per year.

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 syncs directly with continuous glucose monitors like Dexcom and Libre. Garmin and additional integrations are in development, the company said.

All this information is fed into Bevel Intelligence, the company’s core software, which helps analyze key information and tailor recommendations to each user, learning how their body responds to stress, exercise or diet.

Bevel’s story literally started with pain.

Before Nguyen, who previously led products at the Sam Altman-backed Campus, and co-founder Ben Yang, who worked on machine learning at Opendoor, founded the company in late 2023, they built an enterprise stablecoin infrastructure. Due to the demanding nature of startup life, Nguyen took little care of his health. He developed 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 about. Everyone’s life is so nuanced. There are so many little things you do that add up and over time create a chronic condition.”

Nguyen says he started compiling his health data, tracking sleep, diet and steps, and realized that problems in these areas had worsened over time. Low mobility from sitting for too long, sleep problems caused by his mattress setup, and high-sodium meals that worsened the inflammation all played a role.

Similarly, Agarwal, a former CTO at Dropbox and an early engineer at Facebook, had undergone his own health overhaul after feeling burned out from years of intense work. What helped was recording his data manually, through spreadsheets and connected trackers, to rebuild his energy.

When he connected with Ben and Gray about what they were building with Bevel, he saw that they had a similar vision and joined the team.

“We shared the same North Star, which helps people become more intelligent about their own health,” said Agarwal, who is also a partner at South Park Commons. The venture capital firm invested $4 million in Bevel earlier this year along with General Catalyst.

With fresh capital and no plans to venture into wearables, Bevel plans to grow its team and expand horizontally into more services and partnerships that make proactive healthcare accessible.

“Bevel’s mission to democratize health through intelligence and design resonates deeply with us,” said Neeraj Arora, managing director at General Catalyst. “The level of engagement they see from users is remarkable, and it has become part of people’s everyday lives – not just an app. We’re excited to support this team as we build the future of personal health.”
