Impulse Space, a startup building spacecraft that can ferry satellites and other payloads around in orbit after launch, said it has raised $500 million in a Series D funding round. The funding round values the company at $4.26 billion, according to a person familiar with the matter.
The round was co-led by venture firms 137 Ventures and Banner VC and brings the total capital raised by the Redondo Beach, California-based company to more than $1 billion. Additional investors in the Impulse round included Founders Fund, Lux Capital and Linse Capital.
WilmerHale advised Linse Capital in its investment and in connection with raising sidecar funds to invest in the round.
