Valuation
ReOrbit closed a €45 million Series A in September 2025 led by Springvest, with participation from Varma, Elo, Inventure VC, Icebreaker.vc, 10x Founders, Expansion VC, and Yes VC. While the round's valuation remains undisclosed, it reflects an increase from the company's prior funding levels.
The company raised a $7.4 million seed round in September 2023, bringing total funding to approximately €52 million. The seed round included participation from several European venture capital firms specializing in deep tech and space technology.
ReOrbit has allocated its funding toward the development of its software-first satellite platform and the expansion of its manufacturing capabilities, achieving profitability during this period of growth.
Product
ReOrbit develops software-defined satellites designed to operate as networked computers in space rather than traditional fixed hardware. The product suite consists of three integrated components.
Muon functions as the satellite's operating system and avionics package. It abstracts sensors, actuators, and radios behind software APIs, enabling hardware integration through driver layer updates instead of rewriting flight code.
Gluon is a 50-200 kg satellite bus pre-integrated with Muon, along with power and thermal subsystems. Customers can attach payloads such as Earth observation cameras or communication equipment to configure mission-specific satellites.
The company provides two satellite variants: UkkoSat, designed for low Earth orbit missions involving Earth observation and intelligence gathering, and SiltaSat, intended for geostationary orbit communications. Both variants incorporate Muon's autonomous capabilities and support multi-orbit networks via optical or radio frequency cross-links.
Customers interact with ReOrbit satellites using REST-like APIs to schedule imaging tasks, upload AI models, or deploy software updates. The satellites communicate with each other to transfer data across space networks, reducing latency for applications requiring rapid response, such as disaster management or maritime surveillance.
Business Model
ReOrbit operates as a B2B satellite manufacturer with a software-first approach that differentiates it from traditional aerospace companies. The company provides complete satellite solutions to government agencies and commercial customers rather than selling individual components.
The business model integrates hardware sales with ongoing software services. Customers purchase fully integrated satellite platforms and pay for software updates, new capabilities, and network services throughout the satellite's operational lifespan.
ReOrbit maintains asset-light operations by partnering with suppliers such as AAC Clyde and SatixFy for key components instead of manufacturing all parts in-house. This strategy enables faster scaling and lowers capital requirements compared to vertically integrated competitors.
The company's software-defined architecture generates recurring revenue through over-the-air updates and feature deployments. Satellites can be reprogrammed for new missions or upgraded with additional capabilities without requiring physical modifications.
ReOrbit focuses on customers seeking sovereign satellite capabilities, particularly European governments and agencies aiming to reduce reliance on foreign satellite systems. It also serves commercial customers in Earth observation, maritime surveillance, and communications sectors.
Competition
Vertically integrated giants
SpaceX operates the largest satellite constellation globally, with over 8,300 Starlink satellites serving 7 million subscribers. Its vertical integration across launch, manufacturing, and services provides cost efficiencies and pricing leverage that challenge third-party satellite providers.
Amazon's Project Kuiper has launched over 100 production satellites and secured its first commercial airline contract with JetBlue. When fully operational, Kuiper's integration with AWS Ground Station could shift demand for autonomous networking software, a market currently addressed by companies like ReOrbit.
Productized satellite platforms
Apex raised $200 million in Series C funding in April 2025 to expand its Los Angeles factory and accelerate delivery of standardized satellite buses. Its flat-pack Comet bus, offering 5 kW payload power, targets large constellation deployments with pricing under $1 million per 100 kg platform.
York Space Systems has delivered over 130 satellites to the Space Development Agency and acquired ATLAS Space Operations in July 2025 to enhance its ground station capabilities. Its established performance with defense customers intensifies competition in the government market.
Kongsberg NanoAvionics provides satellite buses with four-month lead times and standardized interfaces, competing on speed and cost efficiency. European competitors like Kongsberg benefit from regional preference dynamics that also support ReOrbit.
Software-defined satellite specialists
Startups are increasingly entering the software-defined satellite market, developing autonomous operating systems and networking capabilities similar to ReOrbit's Muon platform. The sector is becoming more competitive as traditional hardware manufacturers incorporate programmable features into their products.
Established aerospace firms such as Airbus and Thales Alenia Space are integrating software capabilities into their satellite platforms, potentially narrowing the differentiation of software-first companies.
TAM Expansion
New products
ReOrbit's Muon operating system expands the company's addressable market by enabling licensing to third-party manufacturers and defense contractors. This approach allows ReOrbit to access a broader satellite market without being limited by its own manufacturing capacity.
The company's GEO communications platform, SiltaSat, targets the sovereign satellite market, where governments are increasingly seeking alternatives to commercial bandwidth providers. This market is growing as nations prioritize communications independence and data sovereignty.
ReOrbit's Earth observation platform, UkkoSat, addresses the global small satellite EO market, which is growing at an annual rate of 12% and is projected to reach €7-8 billion by 2030. The platform's on-board data processing and inter-satellite link capabilities address customer concerns related to latency and data security.
Geographic expansion
Europe's €10.6 billion IRIS² secure connectivity program is driving demand for EU-based satellite suppliers as the region works to reduce reliance on foreign systems. ReOrbit's European heritage and focus on sovereign satellite solutions position it to compete for contracts under this initiative.
ReOrbit has entered the Asian market through partnerships with India's Ananth Technologies for GEO communications satellites and Malaysia's Uzma Berhad for Southeast Asian assembly and launch capabilities. These agreements provide access to local markets and manufacturing scalability.
The company is also targeting emerging markets in Latin America, Africa, and Asia, where governments are developing their first sovereign satellite systems. These regions represent opportunities for complete satellite solutions rather than upgrades to existing infrastructure.
Customer base expansion
Commercial Earth observation operators are an expanding customer segment as private companies invest in their own satellite constellations. ReOrbit's collaboration with Indian analytics firm KaleidEO highlights demand from private operators seeking advanced satellite platforms.
The defense and intelligence sector is growing as military agencies adopt resilient, networked LEO architectures. ReOrbit's secure, software-defined satellites meet defense requirements for adaptable and survivable space systems.
Maritime and aviation connectivity markets are also expanding as industries seek improved coverage in remote areas. ReOrbit's multi-orbit networking capabilities enable it to serve these sectors through partnerships with service providers and direct government contracts.
Risks
Manufacturing scale: ReOrbit faces challenges in scaling production to compete with companies such as SpaceX and Apex, which achieve satellite costs below $1 million through high-volume manufacturing. The company's existing production capacity may be insufficient to support the large constellation deployments that underpin industry economics.
Technology commoditization: Software-defined satellite capabilities are increasingly becoming standard features as established aerospace companies incorporate similar functionality into their platforms. ReOrbit's competitive advantage may diminish as autonomous satellite operations are commoditized across the sector.
Market consolidation: The satellite industry is undergoing consolidation around vertically integrated players that manage launch, manufacturing, and services, potentially reducing opportunities for specialized component suppliers. Large constellation operators may increasingly internalize capabilities currently offered by ReOrbit, shrinking the addressable market for third-party satellite platforms.
