Phononic Vibes, a Milan company that designs and makes noise and vibration control products, has raised €25m (about $28m) in a round led by Jolt Capital. The company and the investor announced the deal on 22 October 2026.
Jolt invested through Jolt Capital V, a fund it said is targeting €1bn and is close to its final close. Existing investors Eureka! Venture SGR, CDP Venture Capital SGR and Simest also took part. The transaction includes Jolt buying the stake held by 360 Capital, which had backed the company since its seed round, so part of the €25m went to an exiting shareholder rather than into the company. The release did not say how much.
Jolt said it is the fund's first investment in Italy. No valuation was disclosed.
“Weight has always been the price of quiet. We have shown it is a design choice, with two of Europe’s most demanding customers.”Luca D'Alessandro, CEO and co-founder, Phononic Vibes
What Phononic Vibes does
Conventional noise barriers, enclosures and silencers rely on mass: blocking more sound means adding more material. Phononic Vibes uses metamaterials, structures whose geometry does the work that weight normally does. The company says its products are up to 30% lighter for the same acoustic performance, or perform better at the same weight.
Its products come out of a design engine protected by 18 patent families, which turns metamaterial physics into certified products and reuses designs across projects. Deutsche Bahn has certified its transparent noise barrier for the German rail network, and Mercedes-Benz uses its technology in series production, which the company describes as the first metamaterial in a production car. Contractors including Webuild and Eteria use its barriers.
The company was founded in 2018 by Luca D'Alessandro, its chief executive, Giovanni Capellari and Stefano Caverni as a spin-off from Politecnico di Milano. It manufactures in Italy and, according to Jolt and EU-Startups, heads a group of European manufacturers that includes Matis, founded in 1979. It said revenue has doubled every year since 2018 and that it reached break-even in 2025, but it did not publish revenue figures.
What the money is for
Phononic Vibes said it will use the money to take its design engine to international markets, apply its technology to new uses and strengthen its delivery capacity. It also plans targeted acquisitions to add industrial capabilities. D'Alessandro named data centres, rail, energy and industry as target markets. The company pointed to demand from data centres, rail networks, energy assets and electric vehicles, and cited figures that one in five Europeans lives with harmful noise levels and that the World Health Organization ranks noise second only to air pollution among environmental health risks.
Andrea Traversone, a managing partner at Jolt Capital, said conventional products had reached their physical limit and that infrastructure needs quieter equipment that takes up less weight and space. Stefano Peroncini, chief executive of Eureka! Venture, said his firm had reinvested in every funding round. Cesare Maifredi, a general partner at 360 Capital, said the company now has hundreds of clients worldwide and described the sale of his firm's stake as a successful exit.
The funding so far
Phononic Vibes closed a €2.3m (about $2.6m) round in 2020, EU-Startups reported. Dealroom said the company's previous round was about €6m (about $6.2m) in 2022. Neither source gave a total for all funding to date.
Dealroom described the new deal as a late-stage round. Target Law advised Phononic Vibes and Orrick Italy advised Jolt Capital on the transaction.
