Fitbit founders James Park and Eric Friedman have announced the launch of a new AI startup called Luffu that aims to help families proactively monitor their health.

The duo are developing an “intelligent family care system” that will start with an app experience and then expand into hardware devices.

Two years after their exit from Google, Park and Friedman are betting on AI to help lighten the mental burden of caregiving.

According to a recent report, 63 million, or nearly 1 in 4, U. adults are family caregivers, up 45% from 10 years ago.

Luffu uses AI in the background to gather and organize family information, learn day-to-day patterns, and flag notable changes so families can stay aligned and address potential well-being issues.

“At Fitbit, we focused on personal health—but after Fitbit, health for me became bigger than just thinking about myself,” Park said in a press release.

“I was caring for my parents from across the country, trying to piece together my mom’s health care across various portals and providers, with a language barrier that made it hard to get complete, timely context from her about doctor visits.

I didn’t want to constantly check in, and she didn’t want to feel monitored.

Luffu is the product we wished existed—to stay on top of our family’s health, know what changed and when to step in—without hovering.

Family information is scattered across devices, portals, calendars, attachments, spreadsheets, and paper documents.

With Luffu, people will be able to track the whole family’s details, including health stats, diet, medications, symptoms, lab tests, doctor visits, and more.

Users can log health information using voice, text, or photos.

Luffu proactively watches for changes, and surfaces insights and alerts, such as unusual vitals or changes in sleep.

The pair told Axios that people can ask questions using plain language to ask about their family’s health, such as “Is Dad’s new meal plan affecting his blood pressure?” or “Did someone give the dog his medication?” Techcrunch event TechCrunch Founder Summit 2026: Tickets Live On June 23 in Boston, more than 1,100 founders come together at TechCrunch Founder Summit 2026 for a full day focused on growth, execution, and real-world scaling.
