Luffu: Fitbit founders bet caregiving beats steps with a $250 LTE health band

James Park and Eric Friedman, the pair who sold Fitbit to Google in 2019 for $2.1 billion, spent the years after the deal building a new company, Luffu, aimed at a different buyer than their first act: the family caregiver. Park, who managed his aging parents' care from San Francisco to Cleveland, has said he used to learn about a condition only after a critical doctor visit; Friedman managed his children's care under the same strain. The founders concluded that caregiver tools were fragmented — location trackers, calendars, fitness bands and emergency pendants that nobody had integrated.

On 2026-08-25 Luffu announced Luffu Link, a screenless LTE wristband at $249.99 preorder ($300 retail) combining all-day health sensing, GPS location, voice logging and a help button that pushes a voice message with the wearer's location and vitals to trusted contacts even without a phone nearby. TechCrunch and Bloomberg (carried in The Mercury News) covered the launch the same day. The Luffu app, in beta since early 2026, uses AI to organize the family health record and flag deviations from a person's baseline, priced at $19/month for four family members.

The bet is that the wearable category's next buyer is not the quantified-self athlete but the caregiver — about one in four American adults — and that 'what changed, does it matter, does somebody need to know' is more valuable than another dashboard of graphs. Park says Link deliberately takes design cues from jewelry so it reads as a quiet guardian rather than a medical device. The band ships early 2027, and a home device extending Luffu into the house is teased as the next step.
