About the company

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

  • NASA selected Orbit Fab on February 16, 2026 for Lunar Gateway fluid transfer.
  • ESA and UK Space Agency funding for ASTRAL validates Orbit Fab across Europe.
  • Peter Shaper’s July 2026 appointment adds commercialization discipline for military and commercial sales.

What critics are saying

  • Orbit Fab still depends on 2027 demos to convert contracts into paid operations.
  • Stride Capital controls financing; a failed Series B leaves Orbit Fab underfunded by late 2026.
  • If RAFTI fails in orbit, Space Force and NASA customers shift to rival servicing standards.

What makes Orbitfab unique

  • RAFTI is Orbit Fab’s standard refueling interface, now adopted in NASA and ESA programs.
  • Orbit Fab has more than $40 million across 24 U.S. government contracts.
  • The company spans interfaces, fuel shuttles, and depot logistics, not just one servicing point.

Orbit Fab raises $25M, appoints new CEO to commercialise satellite refueling

Orbit Fab has appointed Peter Shaper as chief executive and raised over $25 million in interim funding from Stride Capital. The Colorado-based satellite refueling company is transitioning from technology development to commercial operations. Shaper, who has three decades of private equity experience, previously led satellite services companies CapRock Communications and Speedcast. He aims to commercialise Orbit Fab's RAFTI docking and refueling interface technology. The company has three demonstration missions scheduled for the next 18 to 24 months, designed to refuel government satellites using hydrazine fuel shuttles. These demonstrations could unlock over $40 million in contracts for on-orbit refueling services. Orbit Fab is preparing to raise between $30 million and $50 million in a Series B round later this year. The funding will support at least two demo missions in 2027 and initial commercial contracts, targeting primarily US military customers.

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.
