Successful sale of Fos4X to PolyTech

Eight years after our first investment, several financing rounds later and with a great deal of company-building work in between: Fos4X is being sold 100% to PolyTech. This makes Fos4X part of a strongly growing corporate group that increases the output of wind turbines worldwide.

Fos4X was able to combine sensor expertise with application in the rotor blade and thereby provide real added value to turbine manufacturers and operators. This, together with the digital business model and the presence in China, the world’s largest wind energy market, convinced PolyTech.

As a business angel, it is now time to say goodbye and wish Fos4X all the best.
