Overview

Airo Health was a Canadian-American wearable health startup that attempted, twice, to build a passive biometric tracking device—and failed both times.Founded in 2013 by three University of Waterloo engineering graduates, the company first launched a wristband claiming to track nutrition via spectroscopy, drew immediate expert skepticism, and cancelled pre-orders within a month.

After three years of rebuilding, the team pivoted to passive stress and mental health tracking, earned a spot in Y Combinator's Summer 2016 batch, and briefly attracted attention at Demo Day.But with only $125,000 in total lifetime funding, a two-person team, and no documented post-YC raise, the company quietly ceased operations.

The core thesis of failure is straightforward: Airo launched hardware built on scientifically unproven technology with no working prototype in 2013, and then could not secure the capital or team scale needed to ship a validated product in its second act.

Founding Story

Airo Health traces its origins to the University of Waterloo's engineering program, where Naman Kumar, Emmanuel DeVries, and Abhilash Jayakumar met and graduated together. Waterloo's co-op engineering culture—which routinely produces hardware and health-tech founders—provided both the technical grounding and the entrepreneurial context for the team's early ambitions. ^[1]

The company was incorporated in early 2013 as Blacktree Fitness Technologies Inc., based in Kitchener-Waterloo, Ontario. ^[2] The founding insight was behavioral rather than purely technical: the team believed that people failed to improve their health not because they lacked data, but because they lacked clear, actionable next steps. As co-founder Abhilash Jayakumar put it at launch: "There are so many things happening in one's life, that if you don't know what to do next, you won't do it." ^[3]

The original product concept was a pure stress monitor targeting hypertension and heart disease. After early customer conversations, however, the team concluded that users were not interested in a single-function device. ^[4] This led to the first of several pivots: the team expanded the concept into a multi-function wristband that would track nutrition, stress, exercise, and sleep simultaneously—what Jayakumar called "the four pillars of health." ^[5]

The ambition was genuine. Jayakumar articulated a vision that anticipated the behavioral health platforms that would emerge years later: "We built AIRO to help people become more proactive about their health. By aggregating data around the four pillars of health, AIRO notices patterns in your behavior and tells you what you can do, each day, to live a healthier life." ^[5]

The team secured $85,000 in Canadian and Waterloo grants as initial funding—no outside investors, no venture capital. ^[6] With that capital and a concept but no working prototype, they went public in October 2013.

By 2016, the team had changed substantially. Abhilash Jayakumar had departed—the timing and circumstances are not documented publicly. Emmanuel DeVries' role also became unclear. Maryam Jahed joined as co-founder and Product Manager, bringing a digital health product background that would later take her to Woebot, Carbon Health, and Midday. ^[7] The company relocated to Sunnyvale and then San Francisco, California, and applied to Y Combinator. ^[8]
