Hilo (Hilo Health) by Aktiia, a digital health startup developing a next-generation wearable blood pressure monitoring system, secured $19 million in a Series B extension round, bringing its total funding to date to over $119 million.
The investment round was led by Dell Family Office, the family investment office of Michael Dell, Founder, Chairman and CEO of Dell Technologies, alongside continued support from existing backers, reinforcing confidence from leading global technology investors as Hilo expands into the U.S. market.
Originally developed in Switzerland and backed by more than two decades of research, Hilo’s underlying technology has been validated through eight clinical studies and is already used by more than 200,000 people globally. The U.S. launch marks a significant milestone in expanding access to more comprehensive insights, as studies from the American Heart Association show that nearly half of U.S. adults have high blood pressure.
Hilo is developing an advanced complete blood pressure health system called Hilo Core. Hilo Core combines a lightweight wearable band, mobile app, and FDA-cleared connected cuff into a unified blood pressure monitoring system, continuously capturing physiological signals to generate ambient insights using proprietary optical technology and advanced algorithms.
Hilo Core is designed as a wellness product to support awareness and lifestyle optimization, with plans to expand into a regulated medical platform in the future.
“Hilo represents a fundamental shift in how we approach blood pressure, especially in the U.S., where nearly half of adults live with hypertension, and many remain undiagnosed or undertreated,” said Stefan Petzinger, CEO of Hilo by Aktiia.
“For too long, blood pressure has been measured in isolated moments, leaving critical gaps in understanding. By moving to long-term, real-world insights, we’re empowering people and their care teams to take earlier, more informed action and fundamentally change how cardiovascular health is managed. And not only does Hilo provide a more comprehensive view it also puts less daily dependency on the inflatable cuff, a technology developed in 1881 that is not exactly most convenient and comfortable in day-to-day life. “
