Summary
Phononic Vibes, a Milan-based company that designs and manufactures noise and vibration products for rail, energy, industry, construction and mobility, has raised €25 million in a financing round led by Jolt Capital, a Paris-based private equity firm focused on DeepTech growth companies. The investment is made through Jolt Capital V, a fund targeting €1 billion that is nearing final close. Eureka! Venture SGR, CDP Venture Capital SGR and Simest SpA also participated. The transaction includes the acquisition of the stake held by 360 Capital since the company's Seed round. The company, which announced a €2.3 million funding round in 2020, launched a new identity and website alongside the announcement.
Founded in 2018 by Luca D'Alessandro, Giovanni Capellari and Stefano Caverni as a spin-off of Politecnico di Milano, the company manufactures in Italy and leads a group of established European manufacturers, including Matis, founded in 1979. According to the company, its products use metamaterials, structures whose geometry replaces the mass traditionally needed for noise control. The company says its products weigh up to 30% less while delivering the same acoustic performance, or perform better at the same weight. Its proprietary design engine is protected by 18 patent families.
The company reports commercial traction with major customers. Deutsche Bahn certified its transparent noise barrier for the German rail network, which the company says is the first see-through panel it rates as highly absorbing. Mercedes-Benz uses its technology in series production, which the company describes as the first metamaterial in a series-production car. Contractors including Webuild and Eteria select its barriers because they install faster. Revenue has doubled every year since 2018 and the company reached break-even in 2025, according to the company's press release.
Andrea Traversone, Managing Partner at Jolt Capital, described noise control as reaching a turning point, arguing that conventional products have hit their physical limits. He said the investment is Jolt Capital V's first in Italy. CEO Luca D'Alessandro said the new funding will accelerate international growth, expand into new applications, and support the goal of making lighter noise control standard across data centres, rail, energy and industry. The company plans to scale its design engine internationally, extend its technology into new applications, strengthen delivery capabilities, and pursue targeted acquisitions to add industrial capabilities.
