Impulse Space has raised $500 million in a Series D round, extending the Redondo Beach-based in-space mobility company’s financing after its $300 million Series C last year. The latest round is reported to be co-led by 137 Ventures and Banner VC, with participation from Founders Fund, Lux Capital and Linse Capital.
The company was founded by Tom Mueller, a former SpaceX propulsion executive, and has positioned its vehicles around satellite transport and in-orbit maneuvering. The new capital is expected to support fleet expansion, spacecraft production and a larger workforce, with plans to hire up to about 200 employees.
Impulse previously said its Series B lifted total funding to $225 million and its Series C brought cumulative capital to $525 million. The new round is also reported to value the company at about $4.26 billion including the investment.
