James Park and Eric Friedman, the co-founders of Fitbit, know a thing or two about helping people stay healthy. Now, they’re turning their attention to the whole family. Their new startup, Luffu, is an AI-powered platform that helps families monitor and manage health together, from kids to grandparents, and even pets.
At its heart, Luffu is designed to simplify the chaos of family health. Instead of juggling separate apps, spreadsheets, or sticky notes, families can now see everyone’s health information in one place. The AI gathers data from wearables, health apps, portals, and even notes or photos added by family members. Over time, it learns patterns and can give gentle, proactive alerts, like reminders for medications, changes in sleep or vitals, and upcoming appointments.
“What sets Luffu apart is its ability to understand context,” Park explains. “It doesn’t just show data, it gives families answers, like whether a loved one’s blood pressure has changed or if a pet got its medicine today.” Users can ask these questions naturally, just like talking to another person, and the app responds with clear insights.
Privacy is central to Luffu. Everyone controls what information they share and with whom, so sensitive health details remain secure.
Currently, Luffu is available as a mobile app, with a waitlist for early users.
