Momentus Inc. is a U.S.-based commercial space company headquartered in San Jose, California. Founded in 2017, the company's core business revolves around providing in-space infrastructure services, including orbital transportation, hosted payloads, and in-orbit servicing for commercial and government clients.

Under the leadership of Chairman and CEO John Rood, appointed in August 2021, Momentus has pivoted to focus on national security space and advanced orbital robotics, securing contracts with agencies such as DARPA, NASA, and the United States Space Force. Recent notable activities in April 2026 include the completion of the Preliminary Design Review for its Vigoride 8 mission, slated for an early 2027 launch under NASA contracts, and the closing of a $5 million private placement of common stock. The company continues to position itself as a leader in in-space transportation and support services, aiming to enable a more sustainable and accessible space economy.
