Fitbit co-founders James Park and Eric Friedman have launched Luffu, an AI-led family caregiving app designed to cut the mental load of care.
The new company is developing what it describes as an intelligent care system, starting with an app and expanding over time into complementary hardware devices.
The platform is designed for families and their caregivers and uses AI to gather and organise family information, learn rhythms and flag meaningful changes so everyone can stay aligned and act earlier on important wellbeing issues.
Park and Friedman founded Fitbit in 2007 with the aim of making health accessible to all, building a platform used by nearly 150 million people.
The latest caregiving research estimates 63m, or nearly one in four US adults, are family caregivers, up 45 per cent from 10 years ago, according to AARP and the National Alliance for Caregiving in the US in 2025.
The load falls heavily on caregivers in their 40s and 50s, with an average age of 49 and 58 per cent female.
James Park, co-founder of Luffu, said: “At Fitbit, we focused on personal health – but after Fitbit, health for me became bigger than just thinking about myself.
“I was caring for my parents from across the country, trying to piece together my mom’s health care across various portals and providers, with a language barrier that made it hard to get complete, timely context from her about doctor visits.
“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.”
The company said the platform will track health statistics, diet, medications, symptoms, laboratory tests and doctor visits, helping families see the bigger picture so care circles stay on the same page.
Key experiences will include what Luffu calls guardian moments, where the platform watches for changes and surfaces insights and alerts. It will also offer health and medication logging using voice, text or photos, plus connections to devices, health portals and other data sources, alongside health Q&A in plain language.
The platform is designed to let users share key health information with parents, spouses and caregivers.
The company said AI is built into the product to help families capture and organise health information, learn what is normal over time, spot what has changed and get personalised proactive guidance.
Users are in control of what is shared and with whom, and privacy and security are said to be paramount for all family data.
Eric Friedman, co-founder of Luffu, said: “In our house, health isn’t a single person’s project – it’s shared, and I’ve felt how easy it is for my own health to fall to the bottom of the list.
“We’re managing care across three generations – kids at home, busy parents in the middle, and my dad in his 80s who’s living with diabetes and still wants to stay fiercely independent.
“And the moments that matter most are often the most chaotic: a late-night fever, a sudden urgent care visit, a doctor asking questions you can’t answer quickly because the details are scattered.
“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.”
Luffu is launching with a limited public beta.
