€1m · Other round · Semiconductors · Madrid, Spain
Madrid-based Nanostine, a CSIC spin-off developing advanced nanostructured coatings, has raised €1m in funding from national and international private investors, business angels and technology and industrial professionals, including investors introduced through Sego Venture. According to contemporaneous reporting and a later ICMM-CSIC account based on the company announcement, the capital will expand technical and production capacity over the next two years, add strategic hires, support further customer validations and strengthen commercial activity.
Turning custom surfaces into repeatable production
Nanostine uses gas-phase deposition and ultra-high-vacuum processes to make high-purity nanoparticles and coatings whose composition and structure can be tuned for a particular surface. The company says the resulting materials can alter properties needed in sensors, space systems, energy equipment and health applications. Unlike a startup selling one finished component, Nanostine is building a platform for coating components supplied by industrial customers, so its route to revenue depends on translating application-specific development into production work that can be repeated.
That makes capacity expansion commercially important rather than simply a laboratory upgrade. Larger chambers and more production equipment should let the company coat larger parts and move beyond one-off validations, while business-development hiring is intended to turn technical trials into recurring projects. El Español reported that the company planned a move to a larger laboratory and wanted to manufacture coatings in series. The execution test is whether process control established in research can hold across bigger components, more batches and several end markets without turning every customer engagement into a new research project.
Validation narrows technical risk, not the sales cycle
The company says it has validated its technology with industrial partners and organisations including the European Space Agency. Its coatings have been used on radio-frequency satellite devices, where surface performance must hold in demanding operating conditions. That evidence can shorten technical diligence for prospective customers, but it does not by itself create a scalable order book. Nanostine’s stated next step is to convert validations into commercial projects and recurring contracts, making production repeatability and customer qualification the milestones that matter after this round.
Nanostine was formed in 2020 from research at the Madrid Institute of Materials Science and the Institute of Micro and Nanotechnology. The financing therefore backs a familiar deeptech transition: turning protected scientific know-how into manufacturing capability that customers can specify, qualify and buy.
