Swiss healthtech brand Hilo, developed by Aktiia has closed a $19 million Series B extension, bringing its total funding to more than $119 million. The company also announced U.S. launch of Hilo Core, a wearable system designed to help consumers observe blood pressure patterns over time.

The round includes new investment from Dell Family Office, alongside continued backing from existing investors, as Hilo expands its presence in the U.S. following the launch of Hilo Core, its next-generation blood pressure monitoring system designed to provide continuous, long-term health insights.

Hilo Core consists of a connected upper-arm cuff, a smartphone app, and a lightweight wristband. Customers use the FDA-approved cuff to collect standard blood pressure measurements in order to calibrate the wristband, according to MobiHealth News.

The wristband then estimates blood pressure without repeatedly inflating an arm cuff by using photoplethysmographic signals (optical sensors to detect changes in blood flow under the skin) and algorithms.

According to Hilo, it gathers 30 to 35 readings every day, including overnight, and shows trends in addition to heart rate, sleep, and step count information.

"For too long, blood pressure has been measured in isolated moments, leaving critical gaps in understanding," Stefan Petzinger, CEO of Hilo by Aktiia, said in a statement.

According to Hilo, customers may use the system to track how their blood pressure-related patterns vary throughout the day and how they connect to things like activity and sleep.

These trends may encourage a user to consult a healthcare provider or take a traditional reading using the arm cuff.

However, the estimates produced by the bracelet shouldn't be used to replace readings from an FDA-approved medical device, diagnose hypertension, or modify medicine.

The FDA has not authorized Hilo Core.

Instead of presenting it as a tool for detecting or treating a medical ailment, the business is marketing it as a general wellness product meant to increase awareness and guide lifestyle choices.

In the future, Hilo intends to develop its product into a regulated medical platform.
