General Galactic
General Galactic is an El Segundo, California deep-tech startup building water-based propulsion and propellant-generation systems for spacecraft. Its Genesis platform splits water via electrolysis into hydrogen and oxygen, powering a multimode engine that pairs high-thrust chemical burns with efficient electric maneuvering. Founded in 2023 by Stanford-trained, ex-SpaceX and ex-Varda engineers, the company frames itself as the future 'energy and logistics company' of the solar system - and is applying the same electrolysis reactor tech on Earth to turn waste CO2 into fossil-free natural gas.
