Hello and welcome. My name is Matthew Behr, Founder and CEO of AeroCardia. Sometimes I look like this — presenting AeroCardia in front of some of the biggest MedTech experts in Canada at the CLIC innovation competition.

Most of the time, though, I look like this. Exhausted after my first ultra-marathon. Outside of AeroCardia, I spend most of my time outdoors — running, chasing my dog Buoy around in the snow, or getting mildly lost somewhere I shouldn't be.

Why AeroCardia exists

AeroCardia was built for people exploring and living their life — not for a clinic. The device is a portable breath sensor that tracks your breathing patterns and the composition of the air you move — the same kind of data a lab metabolic cart captures, just without the appointment.

That gap is what started this. Detailed breath data has always lived behind an appointment, which means almost nobody gets to see it regularly. I teamed up with Dr. Abhinav Sharma, a cardiologist, to dig into that problem: making this kind of insight something people can get whenever they train, not just on the rare day they're in a lab.

Why estimate what you can quantify. That question is the closest thing AeroCardia has to a philosophy. Wearables are very good at estimating. We wanted to build something that measures instead.

Where we're headed next loops back to where the idea started: bringing breath insights to more people, not just endurance athletes. Same sensor, same principle — measure, don't estimate — pointed at the problem that got us here in the first place.
