fos4X receives 2.3 m Euro Series B financing

March 26, 2015

fos4X GmbH, developer and producer of innovative fiber optic measurement technology, expanded its investor base with Falk Strascheg Holding GmbH (FSH). FSH takes almost half of the current financing round, which secures fos4X an equity inflow of 2.3 m Euro. The other half comes from existing investors Bayern Kapital, High-Tech Gründerfonds (HTGF), UnternehmerTUM-Fonds and Dr. Schulze Holding.

fos4X GmbH develops fiber optic measurement solutions, e.g. to make generation of wind energy more efficient. The fresh equity will be used to further support growths through new product launches. Amongst others, the launch of the certified blade ice detection system fos4Blade BID is on the way. Also, the blade load measurement system fos4Blade ALR for individual pitch control solutions is being integrated into new turbine generations by several wind turbine manufacturers.

Series integration of smart sensors and expansion of product portfolio

Falk Strascheg is convinced: “The further expansion of its product portfolio and mass production are the next steps to secure fos4X the leading position in fiber optic measurement. We are pleased to support the company during these steps. ”

Responsible investment manager at HTGF, Guillem Sague explains: “fos4X has doubled its revenue in three consecutive years. This growth will continue with the newly raised capital.”

The certified product fos4Blade BID helps to avoid ice throw of wind turbines and is one of many application areas where the innovative, more robust sensors of fos4X are successfully used. fos4X sensors are mechanically robust and are made for lifetime measurement. They are immune to lightning and the transmitted light in the fiber optic signal is not affected by electromagnetic fields.

With their customers in the wind industry (including Enercon, Senvion, Nordex) and the railway sector (including Thales, Siemens, Deutsche Bahn) fos4X has realized the first million last year. Managing director Lars Hoffmann is happy: “The integration of our measurement technology into series applications of our customers has made great progress, recently. The money will be invested extremely well in the upcoming scaling! Falk Strascheg is an experienced investor and he has his base in optical metrology. For us, FSH is the perfect complement to the existing investor base.”
