Tom Mueller’s ImpulseSpace Raises $20 Million Seed Round From Peter Thiel’s Founders Fund

EL SEGUNDO, Calif., March 29, 2022 (ImpulseSpace Propulsion PR) — ImpulseSpace Propulsion – leading the development of in-space transportation services for the inner solar system – today announced it has secured $20 million in a seed round led by Founders Fund, the San Francisco-based venture capital firm founded by Peter Thiel whose investments have backed some of the tech sector’s most successful and high-profile startups. Capital will be used by Impulse to further its mission to provide agile, economical capabilities to access any orbit.

“This is an exciting time for both Impulse and the space industry,” says Impulse Founder and CEO Tom Mueller. “With smaller satellites and launch costs decreasing, space is more accessible than ever. There exists, however, the challenge to efficiently move payloads into higher-energy orbits. At Impulse, we don’t see this as a problem needing a solution but rather a question needing an answer. And we’ve got it.”

Behind the Scenes With the World’s Most Ambitious Rocket Makers

An improbable partnership between an Internet mogul and an engineer could revolutionize the way NASA conducts missions—and, if these iconoclasts are successful, send paying customers into space.

Mueller’s ambitious moonlighting caught the attention of Internet multimillionaire Elon Musk, who met the engineer at the warehouse in January 2002 as Mueller was trying to attach his homemade engine to an airframe. Fresh from the $1.5 billion sale of PayPal to eBay, Musk was seeking staff for a new space company, soon to be called Space Exploration Technologies, or SpaceX. He eyed the rocket engine and asked a simple question: “Can you build something bigger?”
