Phononic Vibes Raises €25M Series B Led by Jolt Capital to Scale Acoustic Metamaterial Noise Control

Phononic Vibes Secures €25M Series B

Milan-based noise-management company Phononic Vibes has raised a €25 million Series B round led by Jolt Capital. The round also includes participation from SIMEST, CDP Venture Capital, and Eureka Venture SGR.

What the Company Does

Phononic Vibes is a 2018 spin-off of Politecnico di Milano that designs and manufactures acoustic metamaterial products for noise and vibration control. Its solutions serve the rail, energy, industry, construction, and mobility sectors.

A key differentiator is weight: the company's products weigh up to 30% less than conventional solutions at equivalent acoustic performance. That combination of acoustic performance and reduced mass is relevant for sectors where weight affects efficiency, installation, and system design.

Commercial Traction

Phononic Vibes brings several markers of commercial validation into this round:

• Its technology is certified by Deutsche Bahn.
• It is used in Mercedes-Benz series production.
• Revenue has doubled every year since 2018.
• The company reached break-even in 2025.

The group manufactures in Italy, including through noise-control manufacturer Matis, which was founded in 1979 and has been part of the group since 2025. That acquisition adds a long-established manufacturing base to the group's metamaterial technology.

Why It Matters for Acquisition Watchers

Phononic Vibes sits at the intersection of advanced materials, industrial manufacturing, and noise and vibration control — a category with steady demand across rail infrastructure, energy equipment, construction, and mobility platforms. The company's profile combines deep technical roots (a university spin-off with proprietary acoustic metamaterials) with industrial scale-up (in-house Italian manufacturing and an acquired manufacturer with decades of history).

For strategic buyers, several elements stand out:

• Certified, production-grade technology. Deutsche Bahn certification and Mercedes-Benz series production indicate the technology has cleared qualification hurdles in demanding end markets.
• Demonstrated unit economics. Revenue doubling annually since 2018 and break-even in 2025 suggest a business that has moved beyond pure R&D into repeatable commercial delivery.
• Manufacturing footprint. The Matis integration gives the group control over production capacity in Italy, which can be attractive to acquirers seeking a ready-made industrial platform rather than a licensing story.
• Cross-sector applicability. Rail, energy, industry, construction, and mobility represent multiple demand pools, reducing dependence on a single vertical.

The Round

• Round type: Series B
• Amount: €25 million
• Lead investor: Jolt Capital
• Additional investors: SIMEST, CDP Venture Capital, Eureka Venture SGR

The presence of both a specialist growth investor in Jolt Capital and Italian institutional backers in SIMEST and CDP Venture Capital reflects a mix of private and public-support capital aligned with scaling an Italian industrial technology company.

What to Watch

With fresh Series B capital, the questions for the market will center on how Phononic Vibes deploys the funding: expanding manufacturing capacity through the Matis platform, deepening penetration in rail and automotive programs, and extending into the energy, construction, and mobility segments it already targets. For acquirers and investors tracking industrial noise and vibration control, Phononic Vibes is now a break-even, revenue-growing, certified supplier with its own manufacturing — a combination that tends to attract strategic interest as scale increases.
