Fitbit founders James Park and Eric Friedman announced Luffu, a new AI startup developing an intelligent family care system to help families monitor health. The platform starts as an app and plans to expand into hardware devices, using AI to lighten the mental burden of caregiving.
Park and Friedman exited Google two years ago. A recent report states that 63 million U.S. adults, nearly one in four, serve as family caregivers, marking a 45 percent increase over the past decade. Luffu operates AI in the background to gather and organize family information across multiple sources. The system learns day-to-day patterns and flags notable changes, enabling families to remain aligned and address potential well-being issues before they escalate.
Park drew from personal experience in developing Luffu. In a press release, he stated, “At Fitbit, we focused on personal health—but after Fitbit, health for me became bigger than just thinking about myself.” He described caring for his parents from across the country, piecing together his mother’s health care across various portals and providers. A language barrier complicated obtaining complete, timely context from her about doctor visits. Park noted, “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.”
The consumer health market currently offers tools primarily for individuals. Real-life health management, however, involves shared responsibilities among partners, children, parents, pets, and caregivers. Family information exists in scattered forms, including devices, portals, calendars, attachments, spreadsheets, and paper documents. Luffu consolidates these into a single view for the entire family.
The platform tracks specific details such as health stats, diet, medications, symptoms, lab tests, doctor visits, and additional related data. Users log health information through voice input, text entries, or photos. Luffu then proactively monitors for changes and surfaces insights along with alerts. Examples include notifications for unusual vitals or alterations in sleep patterns.
Users interact with Luffu by posing plain-language questions about family health. The founders told Axios that queries can include “Is Dad’s new meal plan affecting his blood pressure?” or “Did someone give the dog his medication?” These features allow families to access relevant information without navigating multiple disparate sources.
Individuals interested in Luffu can join a waitlist for access to the limited public beta.
