Our take
CesiumAstro is a startup specializing in phased array communications for aerospace applications. It manufactures antennas that support in-flight connectivity and satellite communications, addressing the significant data transfer needs of AI and autonomous vehicles.
This type of communication support is vital nowadays, when the transfer of massive amounts of data is mission-critical. The company's first antenna flew in 2023 as part of a payload for defense contractor CACI International. Plus, it secured a lucrative subcontract with RocketLab to provide antennas for the Space Development Agency.
In 2024, CesiumAstro secured funding that brought its total equity to over $150 million. This investment will fuel the company's expansion, R&D and manufacturing goals. With plans to grow its team and develop new technology, CesiumAstro seems set for continued growth.
