Key Highlights:

• Luffu uses AI to track shared health data across parents, kids, pets, and caregivers.
• The platform flags health changes proactively without constant check-ins.
• The startup launches with an app and plans dedicated hardware later.

Fitbit founders James Park and Eric Friedman have launched Luffu, a new AI-powered startup designed to help families proactively monitor health together. The company aims to reduce the mental and logistical strain of caregiving at a time when family health responsibilities are rising sharply.

Two years after exiting Google, the duo is shifting focus from individual fitness to shared family well-being. Luffu launches as an app-first experience, with dedicated hardware planned for the future.

Why family caregiving is becoming a bigger problem

Family caregiving in the U.S. is growing fast. Nearly 63 million adults now care for a family member, according to recent data. That figure has risen 45% over the past decade. Many caregivers juggle medical updates, medications, diet plans, and appointments across multiple platforms.

Health data often lives in silos. Portals, calendars, messages, lab reports, and paper records rarely connect. This fragmentation makes it harder to notice early warning signs or stay aligned as a family.

How Luffu uses AI to track family health

Luffu uses AI in the background to collect and organize health-related information as life happens. Users can log details using voice, text, or photos. The system learns daily routines and watches for meaningful changes.

The platform tracks shared family data, including vitals, medications, diet, symptoms, lab tests, doctor visits, and even pet care. When patterns shift, Luffu surfaces alerts such as unusual sleep changes or missed medications.

Instead of constant monitoring, the goal is timely awareness.

A personal problem turned into a product

James Park said the idea for Luffu emerged while caring for his parents remotely. Managing care across providers and languages made it difficult to stay informed without frequent check-ins. He said Luffu was built to show what changed, when it changed, and when to step in—without hovering.

Eric Friedman added that the system is designed to reduce chaos by keeping families coordinated and informed at the right moments.

What questions can users ask Luffu?

According to comments shared with Axios, users can ask plain-language questions like whether a new diet is affecting blood pressure or if medication was given on time. The AI pulls answers from the family’s shared health context.

What comes next for Luffu?

Luffu is currently opening a limited public beta through a waitlist. Hardware devices are planned as the system evolves. The founders see Luffu as a shift from solo health tracking to shared health intelligence. In a world where caregiving is becoming the norm, Luffu is positioning itself as a quiet layer of awareness for modern families.
