Impulse Space Secures Major Series C Funding
Space transportation company, Impulse Space, has raised $300 million in a Series C funding round led by Linse Capital. This amount ranks among the largest venture rounds in the history of the space industry, bringing Impulse’s total capital raised to $525 million.
Founded in 2021 by Tom Mueller, a founding member of SpaceX and the architect behind the Merlin engine family, Impulse Space builds spacecraft designed to transport satellites between different orbital positions, serving the growing market for orbital logistics services. As SpaceX's Starship and Blue Origin's New Glenn approach operational status, industry experts anticipate a surge in rideshare missions, where multiple satellites are placed on single rockets, often requiring space tugs to deliver them to precise orbits.
Impulse quickly entered the market with its Mira maneuverable space vehicle, designed for payload hosting and deployment. The company secured 30 contracts valued at nearly $200 million. It is currently developing the Helios high-energy kick stage payload delivery system for Medium Earth Orbit (MEO), Geostationary Orbit (GEO), and beyond, with a projected launch in 2026. Impulse is also working on a customizable GEO Rideshare Program, scheduled to debut in 2027.
“We have demonstrated our ability to build rapidly and achieve successful flights. The market now demands more,” stated Mueller, CEO and founder. “This funding enables us to scale production and enhance technical capabilities to meet those demands effectively. Achieving a true space age is going to require new levels of in-space mobility to move payloads quickly and precisely, both within and between orbits. That capability is what we’re building at Impulse.” Impulse Space’s $300 million round indeed well positions the company to meet the growing demand for in-space mobility across commercial, civil, and defense sectors, which are seeking faster and more cost-effective orbital transport solutions.
In addition to Linse Capital, participants in Impulse’s Series C funding round included DFJ Growth, 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 addressing one of the most technically challenging issues in aerospace with remarkable speed and precision,” said Bastiaan Janmaat, Managing Partner at Linse Capital. “Their vertically integrated approach, proven track record, and swift execution give them a substantial competitive edge. We are enthusiastic about supporting their vision as they develop the infrastructure essential for the next generation of space missions.”
