OrbitFab provides in-space refueling for satellites by deploying propellant depots and using reusable fuel shuttles to create an orbital gas-station network. In practice, propellant such as hydrazine is stored in orbit and delivered to customers’ satellites on demand, with revenue from selling propellant and contracts with operators including the U.S. Space Force starting in 2025. It differentiates itself by building an end-to-end orbital supply chain for propellant and logistics, rather than only servicing satellites, enabling a scalable, recurring fuel infrastructure. Its goal is to establish a practical, ongoing in-space propellant supply system that increases satellite utility and supports broader space industries like manufacturing and tourism.

Simplify's Take

What believers are saying

  • Series B $20M funding accelerates RAFTI production and commercialization.
  • $21M defense contracts with U.S. Space Force ensure 2025 revenue.
  • ASTRAL mission in 2028 unlocks European satellite servicing markets.

What critics are saying

  • CEO Daniel Faber exit destabilizes leadership during Series B transition.
  • 2022 refueling trial delay erodes confidence after $100M funding burn.
  • Northrop Grumman develops proprietary vehicles bypassing RAFTI ports.

What makes Orbitfab unique

  • Orbit Fab deploys RAFTI ports and fuel shuttles for universal satellite refueling.
  • Offers hydrazine at $20M per 100kg in GEO starting 2025.
  • Establishes propellant depots across GEO, LEO, and VLEO orbits.

Orbit Fab raises $20M Series B as CEO steps down amid shift to commercialisation

Orbit Fab has raised $20 million in a Series B round led by Stride Capital as it transitions from developing on-orbit refuelling technology to large-scale commercialisation. The funding will strengthen the company's capital foundation as it enters its next growth phase. Alongside the fundraising, CEO Daniel Faber has stepped down from day-to-day responsibilities. The company has established an Executive Committee to ensure stability and operational continuity during the leadership transition. The round marks a decisive stage in Orbit Fab's evolution as it scales its on-orbit refuelling capabilities.
