About company
E-Space

E-Space is creating an entirely new suite of global capabilities to improve lives, business efficiencies and build a smarter planet.

The E-Space LEO platform will securely connect billions of small, easy-to-install devices deployed anywhere on Earth. Data can then be directly sent to a data center or optimized with Artificial Intelligence (AIoT) to deliver actionable insights and automation that goes beyond traditional IoT sensing and tracking.

As stewards of space, we are committed to setting the standard in the design, build and deployment of sustainable satellite constellations. We also recognize the data captured from our space systems can provide incredible insights into the human impact on our environment. This unprecedented amount of real-time data can help drive clear Environmental, Social and Governance (ESG) decisions to protect our planet.

E-Space is making space universally accessible and affordable, sustainable and secure. We overhauled spacecraft, antenna and terminal design coupled with a new approach to spacecraft deployment to lower total satellite system costs to a fraction of competing LEO systems. By reducing costs, we can empower governments, businesses, communities and individuals to access the power of space to achieve more on Earth.
