CesiumAstro raised a $65 million Series B+ funding round, the Austin-based satellite tech company announced this week. Trousdale Ventures led the round with backing from Development Bank of Japan and Quanta Computer. 

Kleiner Perkins, Lavrock Ventures, L3Harris Technologies, InMotion Ventures, Matter Venture Partners, MESH Ventures, and Assembly Ventures, also joined the round.  The company previously raised a $60 million Series B round in March of 2022. This new funding increases the Series B to a total of $125 million. 

CesiumAstro has developed the Vireo multi-beam Ka-band active phased array payload and the Skylark satcom terminal. Rocket Lab recently selected the phased array for the 18 satellites it is building for the Space Development Agency. 

Cesium said it will use the new funds to accelerate research and development, increase its manufacturing capabilities, and expand facilities and its workforce. In the past two years, the company said it has secured more than $100 million in bookings and revenue, including $90 million in government contracts. 

“We are thrilled to lead CesiumAstro’s Series B+ round,” Phillip Sarofim, founding partner and CEO of Trousdale Ventures said in a news release. “Their innovative technologies are game changers. We have unwavering confidence in Shey’s leadership and CesiumAstro’s team and believe this investment will propel their mission to deliver scalable space tech for a range of applications.”
