€25m · Other round · Deeptech · Milan, Italy
Milan-based Phononic Vibes has raised €25m in financing led by Jolt Capital, with participation from existing investors Eureka! Venture SGR, CDP Venture Capital SGR and SIMEST. Jolt's announcement says the capital will support international expansion, new applications, stronger delivery capabilities and targeted acquisitions.
The transaction also includes Jolt's acquisition of 360 Capital's stake, held since Phononic Vibes' seed round. The announcement does not split the €25m between primary capital for the company and secondary consideration paid to the exiting shareholder, so the full headline amount should not be read as growth cash.
Founded in 2018 as a Politecnico di Milano spin-off, Phononic Vibes designs noise and vibration products around acoustic metamaterials. Instead of relying only on heavier absorbing material, its design engine changes the geometry of structures to manage sound. The company and Jolt say its products can be up to 30% lighter at equivalent acoustic performance and that the engine is protected by 18 patent families.
Certification turns material science into an industrial product
The commercial proposition is not simply a novel material. Phononic Vibes uses its design engine and application libraries to adapt the underlying physics into products that industrial buyers can certify and install. Deutsche Bahn has certified its transparent rail-noise barrier, while Mercedes-Benz uses the technology in series production. Those deployments matter because rail and automotive customers buy against qualification, repeatability and delivery requirements, not laboratory performance alone.
Phononic Vibes' official site describes an acoustic diagnostics lab in the Milan area and a metamaterial manufacturing facility near Parma. The company also owns Matis, an established noise-control manufacturer. That footprint gives the group both development and fabrication capacity, but international growth still requires each product to pass customer-specific engineering and certification cycles.
The round is intended to widen the design engine's application base across data centres, rail, energy and industry, while acquisitions add delivery capacity and established routes to market. This is a practical scaling model for industrial deeptech: reuse a protected design system across applications, then acquire or partner for the manufacturing capabilities needed to deliver certified products rather than rebuilding every production process internally.
Jolt says Phononic Vibes has doubled revenue annually since 2018 and reached break-even in 2025. Those are investor and company claims without disclosed revenue figures, but they indicate that this financing is aimed at scaling an operating industrial business rather than funding first technical validation.
