Open Cosmos Raises €300M Series C for European Space

Europe's sovereignty debate is about to inherit a production schedule. Open Cosmos has raised a €300M Series C led by ETF Partners, giving the satellite company roughly $346.5M at the European Central Bank's September 14 reference rate to expand manufacturing, connectivity, and real-time intelligence services.

The September 14, 2026 financing includes Lightrock, Institut Català de Finances, Entrepreneurs First, two international pension funds, and a broad European syndicate. The capital will expand four factories across the UK, Spain, Portugal, and Greece while accelerating ConnectedCosmos, OpenConstellation, and DataCosmos.

The amount matters because Open Cosmos is trying to join several businesses that are difficult on their own. It wants to build and operate satellites, share orbital infrastructure across customers, carry secure communications, and convert raw imagery into intelligence before events on Earth move beyond the useful decision window.

What Open Cosmos Raised and Who Backed It

ETF Partners' announcement identifies the transaction as a €300M Series C and names ETF Partners as the lead. The full disclosed syndicate includes Lightrock, Entrepreneurs First, Institut Català de Finances, A&G Global Investors, Trill Impact, Phoenix Court, the National Security Strategic Investment Fund, Convex Group, Santander Alternative Investments, Sankara, Ireon Ventures, Sustainable Forward Capital, Endeavor Catalyst Fund, Iberis Capital, Shilling VC, Amena Ventures, Claret Capital Partners, and two unnamed international pension funds.

The ECB reference rate for September 14 was $1.1551 per euro, which places the announced amount at approximately $346.5M. The company and investors did not disclose a valuation, security structure, individual check sizes, ownership changes, or the identities of the pension funds.

Open Cosmos' prior institutional round was a $50M Series B in 2023. At the time, the company said it had raised only $7M in earlier external funding. Those figures establish the financing history, but they should not be combined into a supposedly exact lifetime total without making exchange-rate and completeness assumptions.

The Four Layers Open Cosmos Is Scaling

Open Cosmos has organized the business around four connected layers. OpenOrbit designs, manufactures, launches, and operates satellite missions. OpenConstellation provides shared Earth-observation infrastructure, allowing governments and organizations to use orbital capacity without each financing an independent constellation.

ConnectedCosmos adds a low Earth orbit communications layer built around point-to-point broadband, direct-to-device IoT, and optical inter-satellite links. DataCosmos sits downstream, turning imagery and sensor feeds into operational intelligence that a government or enterprise can use.

The design changes what Open Cosmos is selling. A satellite manufacturer earns revenue by delivering hardware and missions. An integrated infrastructure operator has to keep the spacecraft, network, processing, software, and customer response connected over time. That creates recurring service potential and a much wider operating obligation.

Why Elapsed Time Is Part of the Product

Earth-observation imagery is valuable only while the information can still change a decision. A wildfire front, damaged power line, flooded road, border movement, or communications failure keeps evolving while a satellite image waits for a ground-station pass, processing, distribution, and a human response.

Open Cosmos says OpenConstellation 1.0 can reduce delivery of Earth-observation intelligence from as long as 48 hours to as little as 30 minutes by combining rapid tasking, onboard processing, and inter-satellite communications. That is a company-stated capability, not an independently audited service-level result across a mature fleet, but it gives the investment thesis a concrete unit: time.

The same logic connects Earth observation to resilient communications. ConnectedCosmos is designed to move data through space-based links when terrestrial infrastructure is remote, congested, disrupted, or compromised. Open Cosmos is betting that customers will value the whole route from detection to delivery, especially when sovereignty determines who controls the infrastructure and where the data travels.

The Operating Record Behind the Series C

Open Cosmos reports five consecutive years of profitable growth, more than $370M in contracts signed during the last 3.5 years, and close to 400 employees across Europe. It also says its four factories can manufacture one satellite per day and that its missions have achieved a high success rate in orbit.

Those numbers come from the company. Manufacturing capacity is not the same as realized daily output, signed contracts are not the same as recognized revenue, and a mission-success percentage needs a denominator to show its full meaning. The claims remain relevant because they describe a company raising against factories, customer agreements, launched hardware, and an existing team rather than a presentation of future infrastructure.

The current leadership has also remained unusually intact for a decade-old space company. Rafel Jorda Siquier is Founder and CEO, Jordi Barrera Ars is Co-Founder and CTO, and Aleix Megias Homar is Co-Founder and COO. The Series C gives that group capital to scale engineering, manufacturing, and software at the same time, which is useful precisely because failure in any one layer can slow the rest.

What the Capital Has to Turn Into

The next evidence will come from production cadence, deployed satellites, coverage, latency, reliability, customer adoption, and service economics. Open Cosmos has stated that it can build one satellite a day; the market will learn how often it needs to do so, how quickly those spacecraft reach service, and whether the data products around them create repeatable value.

The company is also operating inside a larger capital shift. Space infrastructure is drawing bigger growth rounds, including DevCuration's coverage of Stoke Space's initial $1B Series E, as governments and enterprises treat launch, Earth observation, and communications as strategic systems rather than occasional science projects. Open Cosmos adds a specifically European version of that wager, built around shared infrastructure and regional control.

The financing gives Open Cosmos room to expand factories and constellations before every customer demand is visible. It also places the company's promise on a broader clock. The satellite has to leave the line, the network has to stay available, the data has to become legible, and the answer has to reach the customer while action is still possible.
