Interlune
Interlune is a Lunar & Planetary company founded in 2020 and based in Seattle, United States. It has raised $18M in total funding, most recently a Seed in 2024.
Founded in 2020 in Seattle by former Blue Origin president Rob Meyerson, former Blue Origin chief architect Gary Lai, and Apollo 17 astronaut-geologist Harrison Schmitt, Interlune is building patent-pending excavation hardware to extract helium-3 from lunar regolith and return it to Earth. The company raised an $18 million seed round (announced March 2024, led by Seven Seven Six) and has since added further capital via a SAFE, alongside government support from NASA, the NSF, the U.S. Air Force SBIR program, and a Department of Energy Isotope Program research grant. Interlune has signed early helium-3 offtake agreements with quantum-cooling firms Maybell Quantum and Bluefors and a historic purchase agreement with the U.S. Department of Energy to deliver three liters of lunar helium-3 by April 2029.
Interlune is one of the few funded bets on an actual lunar resource business model with signed Earth-side offtake contracts, testing whether space mining can be commercial rather than speculative.
