Eclipse Space has an exclusive license to develop Rendered.ai’s Agent Studio platform and an option to acquire its underlying technology.
Eclipse Space is a satellite infrastructure company founded by engineers who built and scaled Starlink.
Eclipse Space is combining the acquired AI engineering team with its satellite, electrical, mechanical, and RF engineers to build tools for designing, customizing, and optimizing large-scale space systems.
Eclipse Space has active engagement with nation-state customers across Europe, Asia, and the Middle East.
Eclipse Space expects its first hardware deliveries later this year.
Eclipse Space’s demonstration satellite is targeted for launch in 2027.
Eclipse Space replicates its fabless model regionally for nation-state customers by standing up in-country production lines with local manufacturing partners.
Eclipse Space says its fabless model supports a minimum production rate of five satellites per day.
Eclipse Space has active engagement with commercial customers in telecom, connectivity, and satellite services.
Eclipse Space has backing from early-stage investors Space Capital, Tectonic, and Ubiquity.
Eclipse Space uses a fabless production model with no owned factories.
Eclipse Space’s planned operational satellites will be able to stack more than 20 units on a single Falcon 9 rocket.
Derek Huerta’s SpaceX equity position after SpaceX’s public offering provided him with resources for Eclipse Space.
Eclipse Space plans to deliver its first customer hardware before the end of 2026.
