Spire builds respiration sensing wearables that take bio-sensing beyond step tracking. Our goal is to make a meaningful impact on the lives of everyone who breathes.

The Spire sensor continuously and accurately tracks respiratory parameters (such as inhalation and exhalation time, apneic events, etc.) and activity (steps, gait, posture) in realtime, streaming raw data to a smartphone or watch, and ultimately to our infrastructure. Each day we collect, store, and process over 4 billion data points.

Spire’s first product, a consumer wearable available at www.spire.io, uses respiratory patterns to infer a wearer’s state-of-mind (tense, calm, focused). A complementary app provides feedback that lowers tension and increases calm and focus in everyday life. Clinical applications of the device and technology are currently being piloted.

Spire is looking to grow our team to continue turning the ideas, energy, and passion of our team into sustained business growth.
