Seven HummingSat orders form a $500M backlog, revenue hit $140M in 2025, and ESA's ARTES program funds in-orbit validation ahead of first delivery to SES in 2027. - Author: Nexi.fund Labs - Tags: Space & Expansion, #mode-5, #hook-number, #track-E Seven washing-machine-sized satellites. That is SWISSto12's entire order book for a product category that used to sell for the price of a stadium. On 16 July the Swiss manufacturer closed a $70 million (โ‚ฌ61 million) Series C to build more of them. ๐ŸŽฏ SWISSto12 has booked seven HummingSat contracts worth over $500 million and generated $140 million in revenue in 2025, at a 110% compound annual growth rate since 2022. The Series C lands alongside an $84.8 million award from European Space Agency (ESA) member states through the Advanced Research in Telecommunications Systems (ARTES) program, funding the platform's development and in-orbit validation. The bet: that legacy GEO operators, squeezed by low-Earth-orbit constellations, will downsize rather than exit geostationary orbit. Geostationary (GEO) satellites are the dinosaurs of the industry. The ones it is replacing flew for decades as school-bus-sized machines costing hundreds of millions, parked 36,000 km above the equator. Starlink and Amazon Leo changed the math. Now operators order spacecraft the size of a household appliance, built with 3D-printed parts, at a fraction of the old price. SWISSto12 was not always in this business. It spun out of the Swiss Federal Institute of Technology in Lausanne in 2011 to print radio-frequency filters and antennas. Fifteen years later it is a systems integrator with its own satellite platform, and it is profitable, growing, and funded by both venture capital and a European space agency. Most startups in this sector cannot match that narrative. ``` TIMELINE: SWISSto12 and the small-GEO transition โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€โ”€ 2011 โ”€โ”€โ”€โ”€ 2019 โ”€โ”€โ”€โ”€ 2022 โ”€โ”€โ”€โ”€ 2026 โ”€โ”€โ”€โ”€ 2027 ๐Ÿงช ๐Ÿ’ฐ ๐Ÿ“ ๐Ÿ’ธ ๐Ÿ”ฅ NEXT EPFL $18M First $70M First spinout Series B Humming- Series C HummingSat RF parts Sat order for SES ``` Chronology per SWISSto12 disclosures and SpaceNews, 2026 ## Why the school bus shrank to a washing machine The old GEO economics were built on scarcity. One satellite covered a continent, so operators paid a premium for the largest possible spacecraft with the longest possible life. Launch was expensive, so mass mattered, and mass meant money. The system worked until LEO constellations made connectivity abundant and cheap. Nobody ordered a $400 million GEO bus the way they did in 2010\. But geostationary orbit still has one thing LEO cannot offer from a single satellite: persistent coverage of a fixed region, for direct-to-device services, broadcasting, and government communications. The question was how to sell it at a price the market would accept. SWISSto12's answer is HummingSat, roughly the size of a household washing machine, built around 3D-printed radio-frequency components. The company's core insight is that 3D printing collapses both lead time and structural mass for the payload, the most expensive part of any satellite. Cheaper payload, smaller bus, faster build. ## Seven orders, four customers, five orbits The order book reads like a roll call of operators that would never have bought a washing-machine-sized satellite a decade ago. SES ordered the first HummingSat, Intelsat-45, for Ku-band media services, with completion planned for 2027\. Viasat booked four Inmarsat-8 spacecraft for L-band safety communications and satellite-based augmentation system (SBAS) navigation, due in 2028\. Astrium Mobile's Neastar-1, Asia-Pacific's first dedicated satellite-to-device platform, is also scheduled for 2028\. Space Compass' SC-A commercial optical data relay follows in 2029. More than 2,000 of the company's HummingLink payload and antenna products are already flying on active missions across LEO, medium-Earth orbit, and GEO. That installed base is what lets it sell itself as both a payload supplier and a satellite integrator. ## The money behind the orders It generated $140 million in revenue in 2025 and says its contracted backlog will drive positive EBITDA in 2026\. Growth has compounded at 110% a year since 2022, when the first HummingSat order was signed. Total capital raised now sits just above $100 million in equity, before this round, a small number for a company with this much hardware flying. The Series C follows a separate $84.8 million award from ESA member states under the ARTES program, announced in January 2026\. ESA is not a customer in the usual sense. It is funding HummingSat's development and in-orbit validation in exchange for a stake in the platform's success, and for a European answer to US satellite dominance. Investors were not disclosed, though the company has disclosed that its 2019 Series B, $18.4 million, was led by Swisscom Ventures and Swisscanto Invest. ## Two business models, one market The small-GEO niche has a rival, and the contrast is instructive. In May, US manufacturer Astranis raised $450 million in equity and debt to expand its own small-GEO production. Astranis owns the satellites it builds and sells their capacity through long-term leases. SWISSto12 sells hardware. Customers buy a HummingSat, launch it, and operate it themselves, often through their own local telecom partners. One model monetizes recurring capacity; the other monetizes a one-time sale with faster cash conversion. For an investor, the difference matters. A lease model produces annuity-like revenue but ties up capital in each satellite. A hardware model turns the order book into backlog, at the cost of not owning the recurring stream. SWISSto12's numbers suggest its route is working: $500 million in contracts from a standing start in 2022. ## What could break the story The order book is real. The risks are execution, not demand. The first HummingSat completes in 2027, five years after the first order. A delay there would echo across the backlog. Launch is contracted but not owned, a dependency every small-GEO player shares. And ESA funding, however welcome, ties the platform's validation schedule to a European institution's timeline. The competitive window is also open at both ends. LEO constellations keep improving, and Astranis has four times the capital. If HummingSat slips, the washing machine loses its size advantage. ## The turning point The pattern here is familiar. As we wrote in [July](https://eclibra.com/apex-satellite-manufacturing-production?ref=nexi.fund), Apex bet $200 million on building satellites like cars. Same logic, opposite end of the market. Apex scales small LEO buses for volume. SWISSto12 scales small GEO spacecraft for targeted regional coverage. The shared assumption is that satellite manufacturing is becoming a production industry rather than a project industry. It is the proof point from the geostationary side: a company printing parts, booking orders, and turning a profit while doing it. ๐Ÿ“Š **Key signals to track** First HummingSat delivery to SES in 2027, on time or not Whether Viasat's four Inmarsat-8 spacecraft launch as scheduled in 2028 Recurring revenue from HummingLink payloads, not just HummingSat sales How the $450 million Astranis war chest changes pricing ## What the small-GEO market means Geostationary orbit was declared dying so often that it became a genre. The obituaries were premature. What died was the school-bus satellite, not the orbit. SWISSto12's Series C is evidence that capital agrees: the future of GEO is small, printed, and cheap enough to sell. Seven satellites. A profitable manufacturer. A European agency writing checks. That is a small story with a large conclusion.
