Sonexos secured CHF 5 million in Pre-Series A funding. This investment propels its patented plasmacoustic technology towards industrial production. The deep-tech solution revolutionizes low-frequency noise control. It offers thin, lightweight, solid-state panels. These address persistent hums from fans and motors. Applications span HVAC, domestic appliances, and critical data centers. Sonexos aims for series production by early 2028. This innovative approach redefines silence in diverse environments. Valquest Partners led the round, with Bosch Ventures participating. The technology reduces noise up to 20 dB, freeing valuable space. It targets a fundamental shift in acoustic engineering.
A Swiss deep-tech innovator just secured significant funding. Sonexos SA announced CHF 5 million in new equity financing. This Pre-Series A round fuels the industrialization of its groundbreaking plasmacoustic technology. The company targets a major shift in noise control. It focuses on low-frequency sounds, a persistent challenge in modern environments.
Engineers face a constant battle. They must balance space, weight, and acoustic performance. Traditional noise solutions often demand bulky materials. Thick foams or heavy barriers occupy valuable room. They also restrict airflow in ventilation systems. These conventional methods struggle significantly with low-frequency noise. This persistent hum permeates walls. It travels through windows. This makes it difficult to escape. Loudspeaker-based active noise control offers some relief. But its effectiveness diminishes in complex, real-world sound fields. It works best in confined spaces like headphones.
Sonexos presents a powerful alternative. Its patented Plasmacoustic Metalayer™ changes the game. This innovative system uses a software-controlled plasma layer. It absorbs sound directly at a surface. The technology is remarkably thin. It is exceptionally lightweight. It boasts no moving parts. This eliminates the compromises inherent in older methods. Prototype systems prove its efficacy. They achieved noise reductions up to 20 dB in ventilation. Domestic appliances saw reductions of 16 dB. These figures compare favorably with premium noise-cancelling headphones. The technology redefines what is possible in acoustic engineering. It opens a much larger design space for noise management.
Valquest Partners spearheaded the funding round. Robert Bosch Venture Capital GmbH (Bosch Ventures) also participated. Industry angels and private investors joined in. Fadi Noureddine from Valquest Partners now sits on the Sonexos Board of Directors. This capital injection is crucial. It supports the transition from engineered prototypes. The goal is qualified industrial products. Funds will also expand engineering and application teams. International intellectual property protection is another priority.
Sonexos is actively engaging manufacturers. Paid prototype-integration programs are underway. Global leaders in domestic appliances and HVAC equipment are participating. These collaborations move the technology closer to appliance-level design-in. Early 2028 marks the target for initial series production. This timeline depends on successful integration, regulatory compliance, and product launch.
The technology’s impact extends across multiple sectors. HVAC systems benefit significantly. Domestic appliances become quieter. Industrial settings gain new acoustic solutions. Data centers present a particularly promising opportunity. The boom in AI infrastructure drives massive cooling demands. Large fans and dry coolers operate continuously. Their low-frequency noise creates problems. It becomes difficult to screen. Operators face community concerns. Noise limits often restrict night-time operation. Quieter cooling allows continuous performance. It avoids adding airflow resistance.
Sonexos is developing specific solutions for this market. The Plasmapanel Radial™ Active Silencer is one such product. It mounts around a fan discharge. It attenuates low-frequency sound. Crucially, it does so without obstructing airflow. This innovation keeps cooling capacity high. It eases environmental concerns. The company partnered with Euronext Milan-listed SIT. This collaboration integrates the technology into fan platforms. It targets data centers, battery energy storage, and industrial cooling. SIT joined the Sonexos Certified Fan Partner Program. A working demonstrator will debut at CES 2027.
The company builds a robust industrial ecosystem. It does not manufacture every component internally. STMicroelectronics supports electronics development. They provide low-power, low-cost solutions. STMicroelectronics named Sonexos a partner in its "ST for Startups" program. A strategic collaboration with Vandewiele Group, via its subsidiary Roj, streamlines European manufacturing. This includes electronics production, box-build, and cabling. Sonexos offers turnkey panels with integration support. It also provides an enterprise model. Larger OEMs can integrate Sonexos components, like Plasmadrive™, and software directly into their production lines.
Sonexos boasts a strong leadership team. Mark Donaldson, CEO and founder, brings decades of active noise control experience. Dr. Stanislav Sergeev, CTO, developed the foundational plasmacoustic technology at EPFL. Andrea Onetti, COO, has extensive experience industrializing semiconductor devices. This team has iterated the technology across three hardware generations. They reduced system weight and volume by over 80%. They integrated plasma architecture, low-power high-voltage electronics, and adaptive control software.
The company's Plasmapanel® encapsulates the active plasma metalayer. It uses a sealed, inert-gas-filled module. Proprietary low-power, high-voltage electronics drive it. These systems absorb sound from 30 Hz to 1,500 Hz. They occupy less than a fifth of the space. They weigh less than comparable passive silencers. This frees up product design space for OEMs. It enables more compact devices. It allows for additional features.
Sonexos holds an exclusive license from EPFL. This covers granted foundational plasmacoustic patents. The company has filed four additional patent families. Two UK patents are already granted. Applications are pending in other major markets. This strong intellectual property position secures its market lead. The investment supports further international protection. Sonexos is pioneering true solid-state plasmacoustic solutions. It promises compact, lightweight, and energy-efficient control of low-frequency noise. This technology will quiet the world around us. It offers superior acoustic performance in various applications. It redefines silence for home, industry, and critical infrastructure. The future of quiet is here.
