On June 3, Impulse Space announced it has raised $300 million in a Series C funding round. The round, led by Linse Capital, brings Impulse’s total capital raised to $525 million.
With over 30 signed contracts (totaling nearly $200 million in value) and growing interest from every sector, Impulse will use the funding to scale and execute a backlog of missions that require faster, more flexible, and more cost-effective in-space mobility.
Led by Tom Mueller, a SpaceX founding member and the architect behind the Merlin engine family, Impulse is powered by a veteran team with a proven history of designing, testing, and delivering. This raise is more than capital—it affirms Impulse’s emergence as the frontrunner for in-space mobility, according to the company.
“We’ve proven that we can build fast and fly successfully. Now, the market is demanding more,” said Mueller, CEO and founder. “This raise helps us scale production and technical capabilities to meet that demand head-on.”
Missions across all sectors—commercial, defense, and civil—are requiring unprecedented levels of in-space mobility. Commercial operators need faster, more cost-effective ways to deploy and reposition satellites. Defense agencies require tactically responsive capabilities to stay ahead of evolving threats. Civil missions depend on precise, flexible movement to support Earth observation and deep space exploration—often on tight timelines and limited budgets. All of these sectors need mobility on demand.
With Linse Capital leading, the round also includes participation from new investor DFJ Growth, as well as returning investors Valor Equity Partners, Founders Fund, Lux Capital, RTX Ventures, DCVC, Airbus Ventures, Spring Tide, First Principles Group, Balerion Space Ventures, Tamarack Global, and Trousdale Ventures.
“Impulse is tackling one of the most technically demanding challenges in aerospace with a speed and precision we rarely see,” said Bastiaan Janmaat, managing partner at Linse Capital. “Their vertically integrated approach, proven track record, and ability to execute quickly in this market give them a real advantage. We’re excited to support their vision as they build the infrastructure that will power the next generation of space missions.”
