deltaVision Raises €10.2M to Build the 'Plumbing' for In-Orbit Refuelling

Company Overview

deltaVision was founded in July 2022 by CEO Alex Plebuch, COO Dr. Denis Kiefel, and CTO Matthias Günther — all experienced aerospace engineers with over a decade of experience in European space programs including the Ariane launcher . The company is headquartered in Munich, Germany, and as of July 2026, employs approximately 125–134 people .

Crucially, deltaVision reports it has been profitable since inception, with the first of its fluidic systems deployed in space in 2025 . This sets it apart from many deep-tech startups that burn cash for years before reaching profitability.

Product Focus: The 'Cardiovascular System' for Spacecraft

deltaVision manufactures what it calls the "cardiovascular system" for spacecraft: fluidic systems that include valves, pumps, pressure regulators, solenoid valves, and electric pressure regulators . These components control the transport of liquids, fuels, and pressurised gases — including cryogenic fluids such as liquid hydrogen — across a range of space vehicles . The company's product line includes solenoid valves, regulation valves, pressure regulators, and even cryogenic in-runner BLDC motors .

Customer Base and Market Traction

With over 60 customers across four continents, deltaVision's client list spans startups, national space agencies, and established industrial primes . A particularly notable customer is the European Space Agency (ESA), for whose Argonaut lunar lander deltaVision is supplying approximately 50 individual products per mission .

In April 2026, U.S.-based Mott Corporation began offering deltaVision's valve solutions to North American spacecraft manufacturers, marking a major step in transatlantic market expansion .

Production Scaling

The company plans to scale its annual production capacity to 5,000 components per year, up from its current footprint in a 4,800 m² factory . According to CEO Alex Plebuch, approximately 70% of the new funding will be used to grow manufacturing output by a factor of five .

Orbital Refuelling Technology: The Bigger Bet

While deltaVision's core business is supplying fluidic components, its longer-term focus is on enabling in-orbit refuelling. The company is developing a modular orbital refuelling technology stack comprising fluidic couplers, utility interfaces, and integrated refuelling modules that allow two spacecraft to dock and transfer propellant .

DeltaVision is not positioning itself as a mission operator. Instead, it focuses on supplying the components and sub-systems that will allow other companies and agencies to build refuelling capabilities . The company's first integrated refuelling payload is scheduled to launch into orbit in March 2027 .

In a statement quoted by multiple outlets, CEO Alex Plebuch framed the company's vision around supporting an "open and interoperable" in-orbit servicing ecosystem, as opposed to a closed proprietary standard . The company aims to be the "customer's choice and European technology leader" for advanced cryogenic fluid control systems .

Geographic Expansion

To support growing demand, deltaVision is investing in international expansion. The company is establishing a new French subsidiary (deltaVision SASU) and building U.S. valve manufacturing capacity, supported by its partnership with Mott Corporation in Connecticut . Approximately 30% of the new funding will be allocated to research and development, along with international expansion efforts .

What This Means for the Space Economy

deltaVision's funding round signals growing confidence in the orbital services economy. By focusing on the "plumbing" — the unglamorous but essential hardware that controls propellant flow — the company is betting that a growing number of spacecraft will need refuelling, and that they will need interoperable, standardised components to do it. With a profitable base business, a blue-chip customer list, and a clear roadmap to in-orbit demonstration, deltaVision is positioning itself as a foundational supplier for the next phase of space operations.
