Fitbit founders launch AI health platform for family care
Fitbit co-founders James Park and Eric Friedman have launched Luffu, an AI-powered ‘intelligent family care system’ that consolidates health and caregiving data for multiple family members to help detect changes and support wellbeing.
Fitbit co-founders James Park and Eric Friedman unveiled a new AI startup, Luffu, aimed at helping families monitor and organise health, safety and caregiving information across household members and caregivers.
The platform begins as a mobile app that uses background AI to aggregate data from devices (including Fitbit and Apple Health) and family-entered information like medications, symptoms, lab results and doctor visits.
Luffu’s AI learns everyday patterns, flags notable changes (such as abnormal vitals or sleep shifts), and provides proactive alerts and plain-language insights, easing the administrative and emotional burden of caregiving.
Users can log data by voice, text or photos, and even ask conversational health questions about family members’ well-being.
Currently in private beta with an open waitlist, Luffu is positioned as a family-centric health coordination hub rather than a medical diagnostic tool, with plans to expand into complementary hardware devices in the future.
