We hear you, Earth.

The space company focused on the future of Planet EarthTM

Spire harnesses the world’s largest constellation of 100+ multipurpose satellites to hear land, sea, and air to accelerate global commerce and to enable organizations to make smarter, better, faster decisions in a rapidly changing world impacted by climate change.
See it in action

See, talk, listen.

When you listen, you observe. When you hear, you listen, observe, absorb, understand, and act.

Using the world’s largest multipurpose constellation of 100+ “listening” satellites in space, Spire does both, and that reliably delivers smarter, more actionable data than satellites that only see or talk.

Through Spire’s constellation, we hear all aspects of Earth’s heartbeat. We hear it breathe, laugh, and cry. From the white capped ocean wave to its highest most magical cloud, to the dirt that girds our path forward, Spire listens to Earth. Spire hears data about Earth, that was previously unattainable, and more accurate. All businesses are affected by weather and the impacts of extreme events driven by climate change. Through historical, present observations and accurate weather forecasts, Spire helps businesses weather the storm of climate change. We listen. Hear. Act. All to help build a more sustainable, equitable and prosperous future for all humans, and help save property, lives, and the very Pale Blue Dot we call home – the only one we have.

Spire’s Technology Difference series

Find out the foundation of Spire’s core technology pillars and differentiators, and hear from CEO Peter Platzer on how some problems can only be solved from space.

A key component that makes Spire’s satellites different is that they’re software-defined, meaning they can constantly be updated once they’re in orbit.

A message from our CEO

“We made our satellites multi-purpose. So that means that every single individual device is serving multiple verticals and multiple industries because it has multiple sensors tracking completely different data. They are listening satellites. They generally use radio frequency to observe previously unattainable and accurate information about the Earth.”
