Luffu
AI family-care system from the Fitbit founders: health app, care circle and LTE safety band
Luffu, Inc. is a San Francisco consumer health company founded by Fitbit co-founders James Park (CEO) and Eric Friedman (CFO), who left Google in January 2024. Incorporated in Delaware and registered in California in September 2024, it unveiled itself on February 3, 2026 as an 'intelligent family care system': an AI app that gathers a family's health information from voice, text, photos, connected devices and health portals (including Apple Health and Fitbit), learns each person's routines, surfaces alerts on meaningful changes such as missed medications or unusual vitals and sleep, answers plain-language questions, and shares selected data with a 'care circle' of parents, spouses and caregivers. On August 25, 2026 it announced Luffu Link, a $299.99 screenless LTE health and safety band (5-day battery, GPS, help button, LTE included) shipping early 2027 and requiring a $19.99-$29.99/month Family Plan, with a home device teased. The company describes itself as self-funded; no outside round, investors or valuation have been disclosed, and no SEC Form D was on file as of August 2026.
