Make Each Breath Count

The world's first wearable device to track breathing patterns.

The Story Behind Spire


For the last 5 years, our team has been building technology that puts the human experience – in all its randomness and unpredictability, its laughter and tears, its joy and sorrow – at its center. We have been building a company that brings us closer to ourselves, to each other, and to the earth, in ways unimaginable a few years ago.

It was in this mindset that we created Spire, a device that, for the first time, captures your breathing patterns – signals that reveal that same laughter and tears, that same joy and sorrow – throughout your day, and makes them meaningful and actionable.
