fos4X develops fiber optic sensor technology and software for wind turbine monitoring and optimization, marketed under its fos4Blade modular measuring system. The system acquires multiple physical quantities of rotor blades and uses sensor data fusion, classical model-based methods and machine learning to calculate inputs for control and operational optimization. The company supports all of the top 10 wind turbine manufacturers and has applied for more than 100 patents covering technology, sensors and applications. Its solutions are also used in other industries, for example fiber-optic temperature measurement in e-mobility. Led by Alexander Tindl, fos4X plans to use the new funding for internationalization, scaling and expansion of its digital business. fos4X develops and produces fiber optic measurement technology aimed at improving wind‑energy generation and serving the railway sector. The company’s products include the fos4Blade ALR blade load measurement system, which is being integrated into new turbine generations by several manufacturers. It plans to launch a certified blade ice detection system (fos4Blade BID). fos4X serves customers in the wind industry (including Enercon, Senvion, Nordex) and the railway sector (including Thales, Siemens, Deutsche Bahn). Founded in 2010 and based in Munich, Germany, the company intends to use the new funds to launch additional products. fos4X develops and sells monitoring and control solutions for wind turbines, with technology based on fiber optic measurement for rotor blades and expertise in wind generation. The company’s systems aim to improve monitoring of technical structures and constructions, particularly those made of newer materials such as fiber reinforced plastics and resins. Led by CEO Dr. Lars Hoffmann, fos4X serves industrial clients in the wind sector; its first client was SSB Wind Systems GmbH. The firm is using its technology to extend its product portfolio and address structural monitoring needs in wind energy. fos4X is based in Munich, Germany, and intends to scale the business using proceeds from its recent financing. No operating metrics were disclosed in the article. fos4X is a Munich, Germany-based fibre-optic measurement startup founded in 2010 as a spin-off of Technische Universität München. It was founded by Dr. Thorbjörn Buck, Dr. Lars Hoffmann, Dr. Matthias Müller and Rolf Wojtech. The company has developed fibre optic sensors that can measure wind force on the rotor blades of wind turbines. Its solutions are intended to increase the efficiency of wind power plants. fos4X has received an undisclosed equity investment from High‑Tech Gründerfonds, Bayern Kapital, UnternehmerTUM’s venture capital fund and private business angels. The company intends to use the funding to support its market entry.
