Impulse Space this week said its raised $300 million in a Series C funding round to scale production and add talent to meet demand for its in-space mobility vehicles.
The raise was led by Linse Capital
and brings Impulse’s total capital raised to $525 million.
Impulse Space has built and flown its Mira orbital transfer vehicle, which is for payload hosting and deployment, serving two separate customer missions. The California-based company also says it has more than 30 government and commercial contracts, and conducted what it believes are the two largest orbital maneuvers using its nitrous-based propulsion system.
The four-year-old company is also targeting 2026 to fly its Helios high-energy kick stage rocket that will rapidly deliver payloads from low Earth orbit to medium Earth orbit, geosynchronous orbit, and beyond.
The new funding will help scale production of Mira and Helios.
“We’ve proven that we can build fast and fly successfully,” Tom Mueller, Impulse’s founder and CEO, said in a statement. “This raise helps us scale production and technical capabilities to meet that demand head-on.”
Impulse plans to boost hiring across engineering, manufacturing, and mission operations, while also strengthen its vertical integration to control cost, quality, and schedule. The funding will also be put toward integrating electric propulsion for longer missions, and developing new vehicles for national security and NASA missions.
Participants in the funding round include new investor DFJ Growth, and returning investors Valor Equity Partners, Founders Fund, Lux Capital, RTX Ventures [RTX], DCVC, Airbus Ventures, Spring Tide, First Principles Group, Balerion Space Ventures, Tamarack Global, and Trousdale Ventures.
