Highlights continued investor confidence in space defense tech amid government spending surge
Impulse Space, founded by SpaceX engine expert Tom Mueller, raised $500 million Series D led by 137 Ventures and BANNER VC to hire up to 200 employees and build maneuverable spacecraft for U.S. Space Force and satellite deployment.
The funding round includes participation from Founders Fund, Lux Capital, and Linse Capital, reflecting investor interest in space defense tech as the U.S. government increases national security spending. Impulse develops the highly maneuverable Mira platform for Space Force and Helios vehicle for rapid satellite deployment to high orbits. President Eric Romo, SpaceX's 13th employee, emphasized hiring plans amid aerospace talent competition. While software teams use AI coding tools, Romo said AI isn't ready for real-world engineering problems, noting training data scarcity compared to text/code for LLMs. The company recently opened a Colorado office to access distributed aerospace talent beyond traditional Los Angeles hub. Next Mira mission planned before year-end following previous flight's navigation issues.
