James Park and Eric Friedman built Fitbit into a household name. Now, two years after leaving Google, they’re back with something different. Their new startup, Luffu, uses artificial intelligence to help families keep track of everyone’s health—from aging parents to household pets.
Key Takeaways:
- Luffu is an AI-powered “intelligent family care system” from Fitbit’s original founders, starting as an app before expanding into hardware
- The platform addresses a growing need: 63 million U.S. adults now serve as family caregivers, a 45% increase over the past decade
- Users can log health data through voice, text, or photos, while AI monitors for notable changes and surfaces timely alerts
The idea grew from personal frustration. Park found himself managing his mother’s healthcare from thousands of miles away, navigating multiple patient portals, coordinating with various providers, and working through a language barrier that made every doctor visit harder to understand.
“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,” Park said.
Current consumer health tools focus almost entirely on individuals. But health doesn’t exist in isolation. Partners share concerns. Parents manage children’s medical appointments. Adult children track elderly parents’ medications. Someone has to remember when the dog last got his heartworm pill.
Luffu gathers all of this into one place. The AI runs quietly in the background, organizing family health information, learning daily patterns, and flagging anything unusual. Users can track health stats, diet, medications, symptoms, lab results, and doctor visits for every family member—humans and animals included.

Want to know if a new diet is actually helping? Ask in plain English: “Is Dad’s new meal plan affecting his blood pressure?” Curious whether anyone remembered the morning routine? Try: “Did someone give the dog his medication?”
“We designed Luffu to capture the details as life happens, keep family members updated and surface what matters at the right time—so caregiving feels more coordinated and less chaotic,” Friedman said.
The numbers behind the venture explain the timing. According to recent data, 63 million Americans—nearly one in four adults—now serve as family caregivers. That’s a 45% jump from a decade ago. As the population ages and sandwich-generation responsibilities multiply, families need better tools than scattered spreadsheets and forgotten calendar reminders.
Luffu plans to launch first as an app, with hardware devices coming later. A limited public beta is now accepting signups through their waitlist.
