Orbital compute startup Sophia Space and space asset leasing company SLI have set terms for a $300M asset-financing deal, the companies announced today.
Under the framework, SLI would fund construction of a 10-satellite edge computing constellation against build and launch milestones, take ownership upon in-orbit acceptance, and lease them to Sophia’s customers.
Both companies are betting that space is entering its infrastructure capital era. As a result, they’re relying on the same financing tools that built aviation and shipping.
“When you start being able to have a finance scenario like this for a nascent industry, that industry is no longer nascent,” Sophia Space CEO and cofounder Rob DeMillo told Payload.
Fine print: Sophia and SLI laid out the $300M framework, covering 10 TILE spacecraft, in a non-binding letter of support.
- SLI would own the satellites under a long-term operating lease.
- Launches would come as early as 2028, with the full constellation delivering capacity the company says is equivalent to 240 state-of-the-art edge servers.
- Sophia’s customers, not Sophia, would lease the satellites, according to DeMillo.
Opex over capex: The lease structure transforms a capital purchase into an operating cost for orbital compute buyers, giving Sophia a payment pathway to put in front of prospects.
DeMillo compared the process to leasing a car. “They don’t have to go from ground zero to get their car lease. Basically, they can come through us,” he explained. “Instead of leasing from a bank, they go to the Audi dealership.”
Conditions apply: DeMillo said the framework only converts once Sophia closes its final round of financing. The company has raised $22M, following a $10M February seed round and a $7M June SAFE financing round.
No customers have committed to a lease yet either, though DeMillo noted that the pipeline is real. Landing those buyers, he acknowledged, is Sophia’s responsibility.
Building pipelines: Since 2023, SLI has been working its way from ground stations to orbit with a pipeline of leasing deals.
- AscendArc: SLI signed a non-binding document last December to buy two GEO satellites—valued at over $200M—and lease them to operators.
- Ground segment: SLI’s earlier deals include an Arctic ground station and 10 antennas acquired from Microsoft, both leased to RBC Signals.
DeMillo expects more companies to follow the leasing route. “You build the initial stuff with venture money, yes. But then you productize it, and when you productize it, you need different capital investment structures.”

Tomorrow.io Unveils Next-Gen Weather Forecasting Instruments
Tomorrow.io announced the five instruments that will fly aboard DeepSky—its next-gen constellation built for real-time global atmospheric monitoring.
For decades, the model for building national security space systems was relatively straightforward. The government defined a mission, established requirements, funded a spacecraft designed specifically to meet them, and ultimately owned and operated the resulting capability.
That model isn’t disappearing. But the environment has changed.
Lower launch costs, proliferated low Earth orbit (LEO) architectures, private investment, and advances in sensors, computing, and manufacturing have created a commercial space ecosystem capable of putting sophisticated technology on orbit faster than traditional acquisition cycles can move.
