Fitbit founders James Park and Eric Friedman have Office has partnered the launch of a new AI startup called Luffu that aims to help families proactively monitor their health. The duo is developing an “intelligent family care system” that will start with an app experience and then expand to hardware devices.

Two years after they left Google, Park and Friedman are betting on AI to help ease the mental burden of caregiving. According to a recent report63 million, or nearly 1 in 4, US adults are family caregivers, up 45% from 10 years ago.

Luffu uses AI in the background to gather and organize family information, learn daily patterns, and flag unusual changes so families can stay aligned and address potential welfare issues.

“At Fitbit, we focused on personal health—but after Fitbit, health for me became bigger than thinking about myself,” Park said in a press release. “I take care of my parents from all over the country, trying to integrate my mom’s health care with different portals and providers, with a language barrier that makes it difficult to get a complete, timely context from her about the doctor’s visits. I don’t want to always check in, and she doesn’t want to feel monitored. Luffu is the product that we want to exist – and to stay on top of the health of what has changed in our family.”

The pair noted that today’s consumer health market is filled with tools for individuals, but that real-life health is shared by partners, children, parents, pets, and caregivers. Family information is scattered across devices, portals, calendars, attachments, spreadsheets, and paper documents.

With Luffu, people can track the details of the entire family, including health statistics, food, medication, symptoms, lab tests, doctor visits, and more. Users can log health information using voice, text, or photos. Luffu actively monitors changes, and displays insights and alerts, such as unusual vitals or sleep changes.

The pair Axios said that people can ask using simple language to inquire about their family’s health, such as “Is Dad’s new diet plan affecting his blood pressure?” or “Did someone give the dog its medicine?”

“We designed Luffu to capture the details as life happens, keep family members updated and show what’s important at the right time—so care feels more coordinated and less chaotic,” Friedman said in the press release.

People interested in Luffu can join the waitlist for a limited public beta.
