Co-Founder & CEO
Spaceium builds unmanned stations that refuel and repair spacecraft in orbit. Its cryogenic technology stores and transfers propellant with zero loss, and a proprietary modular robotic arm transfers fuel to any spacecraft design. Ashi specializes in orbital mechanics and rocket propulsion. She has worked on aerodynamic models for NASA and real-time simulation models for uncrewed asteroid return missions, and has built rocket engines, payload structures and recovery systems. She and Reza met leading the University of Ottawa's rocketry team. Spaceium (YC S24) reports $86.1M in binding commercial contracts, a further $230M in the pipeline and $1B in letters of intent. It raised a $6.3M seed round led by Initialized Capital in January 2025.
Ashi Dissanayake is the co-founder and CEO of Spaceium, which builds automated stations that refuel and repair spacecraft in orbit. She specializes in orbital mechanics and rocket propulsion, and has built aerodynamic models for NASA and hardware including rocket engines, payload structures and recovery systems.
A Y Combinator S24 company building fully automated, unmanned service stations in space. Its long-term plan is a network of stations along the route from Earth to the Moon and Mars, so missions can carry more payload and travel further.
Cryogenic fuel storage and transfer that keeps extremely cold propellant with zero loss in space, and a proprietary modular robotic arm that can transfer fuel to any spacecraft design rather than to one docking standard.
Launch vehicles, orbital transfer vehicles, moon landers and other spacecraft that benefit from more payload capacity and longer range.
The company reports $86.1M in binding commercial contracts, $230M more in the pipeline and $1B in letters of intent.
An oversubscribed $6.3M seed round led by Initialized Capital, announced in January 2025, with Y Combinator among the other investors.
