Synchronicity would extend CesiumAstro's business from supplying space technologies and complete spacecraft to developing and operating its own space infrastructure. The planned 737-satellite constellation is intended for commercial, sovereign and defense missions.1
Janus Henderson led the equity round, with participants including Insight Partners, Sands Capital and Magnetar. The announcement also lists $100 million in debt financing through the Export-Import Bank of the United States and JPMorgan, without specifying whether that amount is included in the $730 million.1
CesiumAstro acquired Jariet Technologies, 1Aardvark and Vidrovr in the past 12 months, bringing together semiconductor, mission software and artificial intelligence capabilities.1
The company says the capital will support Synchronicity deployment alongside advanced technologies, U.S. manufacturing expansion, spacecraft development and international growth. It also announced a $500 million investment over five years to expand its Austin headquarters, including advanced manufacturing space.1
