What parsimoni does
Parsimoni builds SpaceOS, a secure, hardware-agnostic payload operating system for satellites, spun out of the OCaml and MirageOS unikernel research lineage originating at the University of Cambridge. SpaceOS boots in its own partition on the payload computer alongside existing flight software, providing unikernel-based application runtime with hardware-backed isolation via Type-1 hypervisors (KVM, Xen, Muen), a CI/CD lifecycle with A/B partition rollback, and post-quantum cryptography. The product portfolio includes SpaceOS Hub (operator marketplace), the ESA-backed Satellite App Store, and Borealis, a pure-OCaml implementation of the CCSDS protocol stack with Over-The-Air Rekeying. Parsimoni has reached orbit twice, on Clustergate-1 (March 2025) and Clustergate-2 (March 2026).
The company serves three primary customer segments: satellite operators with underutilised on-board compute (NASA JPL data cited at ~10% average utilisation), payload hardware manufacturers seeking differentiated software capabilities (Innoflight, OHB Hellas, KP Labs, Blackwing Space), and space application developers who deploy via the Satellite App Store. Named enterprise partners include Thales Alenia Space (validation partner since 2023), OHB Hellas, Innoflight, DPhi Space, KP Labs, ANT61, and Blackwing Space, with the European Space Agency providing institutional backing for the app store and funded R&D.
Parsimoni's commercial model is a value-sharing platform fee of 10-15% on incremental revenue operators earn from third-party workloads or on savings from on-board processing, with no upfront cost and Parsimoni absorbing integration risk. The company is headquartered in Pau, France, with a U.S. presence established in California in 2025, operates with 1-10 employees, has secured EUR 1.5M+ in non-dilutive funding from Horizon Europe, BPI France 2030, and ESA, and was selected for the Techstars Space Accelerator (Fall 2025) and Starburst Paris accelerator. No institutional equity round has been disclosed, and the company is pre-revenue under its transaction-fee model.

Revenue model
- Platform Fees on Third-Party Workloads: Operators keep their satellites and flight software. Parsimoni integrates SpaceOS at its own expense with no upfront cost. In return, Parsimoni takes a 10-15% platform fee on new revenue operators earn from third-party workloads hosted via the Satellite App Store.
- Platform Fees on Cost Savings: Same fee structure applies to savings operators realize from on-board processing (e.g., downlink cost reduction from processing data in orbit rather than transmitting raw data). If it doesn't pay, Parsimoni doesn't get paid.
- Funded R&D Projects: EUR 1.5M+ in funded project commitments across ORCHIDE (Horizon Europe with Thales Alenia Space), CEOS (BPI France 2030), and OSIP (ESA marketplace demonstration). Non-dilutive funding for technology development.

Product offeringCore offering
Parsimoni develops SpaceOS, a secure payload operating system and Satellite App Store for managing satellite software and in-orbit computing. SpaceOS runs in its own partition on the payload computer alongside existing flight software, enabling satellite operators to deploy, update, and monetize third-party applications in orbit using unikernel-based technology with hardware-backed isolation and zero-trust security.
Product overview
Parsimoni offers SpaceOS as its flagship middleware product — a secure, hardware-agnostic payload operating system that runs alongside existing flight software on satellites. SpaceOS enables satellite operators to deploy, update, and manage applications in orbit using unikernel technology with hardware-backed isolation. The product portfolio includes the Satellite App Store (ESA-backed marketplace for third-party applications), SpaceOS Hub (operator marketplace interface), and supporting developer tools. The underlying Borealis project provides a pure-OCaml CCSDS protocol stack for satellite communications. The company targets operators with idle compute capacity, defense/government missions requiring cyber-resilience, and developers building space applications.

parsimoni competitors and assessment
Company assessmentBroad incumbents
- Airbus Defence and Space: European aerospace prime with proprietary satellite payload software and avionics across commercial and defense missions. Listed as a Parsimoni ecosystem partner, but represents the broad incumbent alternative Parsimoni must displace.
- Planet Labs: Large commercial Earth observation operator running proprietary software-defined satellites with on-board processing capabilities. Represents the vertically integrated incumbent model that Parsimoni's app store approach is designed to unbundle.
- Loft Orbital: Provides satellite-as-a-service, hosting third-party payloads and applications on standard satellite buses. Comparable business model in that it abstracts satellite operations for payload customers, though it owns the bus rather than licensing OS software.
- Spire Global: Software-defined smallsat operator with custom payload software and hosted-app business model (Spire hosted payloads). Represents an incumbent version of the software-defined satellite approach Parsimoni enables for others.
- Thales Alenia Space: European space prime that has validated SpaceOS workloads since 2023. Operates its own payload software across telecom, EO, and exploration missions — directly comparable as both validation partner and competing framework provider.
Direct peers
- Satellogic: Earth observation constellation operator with significant on-board processing capability and AI analytics. Comparable as a satellite operator exploring monetization of payload compute through third-party applications and analytics services.
- Ubotica Technologies: Provides on-board AI and computer vision software for satellite payload processing. Closely comparable to Parsimoni as both deliver in-orbit compute platforms enabling Earth observation apps and third-party workloads on satellite hardware.
- KP Labs: Builds Leopard DPU onboard data processing hardware for satellites and offers its own AI software stack. Listed as a Parsimoni partner, but operates an adjacent (and partially overlapping) on-board compute platform serving the same EO/AI market.
Emerging players
- DPhi Space: Operates ClusterGate hosted-payload missions where SpaceOS first reached orbit. Provides shared satellite infrastructure for technology demonstration — directly comparable as an emerging player in hosted payload services.
- Innoflight: U.S. flight computer manufacturer (CFC-400XS, 200+ sold, 50+ in LEO/GEO) now OEM-embedding SpaceOS. Comparable as a payload hardware provider in the same commercial ecosystem, and a direct distribution partner for Parsimoni.
