Milan-based Phononic Vibes raised a €25M (~$27.0M) follow-on financing led by Paris-based Jolt Capital via its Jolt Capital V fund — targeting €1B and nearing final close — with Eureka! Venture SGR, CDP Venture Capital SGR and Simest SpA, including the acquisition of 360 Capital's stake held since the Seed round, following its €2.3M round in 2020. Founded in 2018 as a Politecnico di Milano spin-off, the company reports revenue doubling every year since 2018 to reach break-even in 2025, holds 18 patent families for its proprietary metamaterial design engine that delivers the same acoustic performance with up to 30% less weight, and counts Deutsche Bahn — which certified its transparent barrier as the first highly-absorbing see-through panel for the German rail network — Mercedes-Benz — first metamaterial in a series-production car — Webuild and Eteria as clients. The capital will back scaling of its Italy-based manufacturing and group company Matis (founded 1979) to build a global leader in noise and vibration control for rail, energy, industry, construction and mobility, marking Jolt Capital V's first investment in Italy.
