Fos4X, a Germany-based developer and producer of fibre optic measurement technology for wind turbines (pictured), has expanded its investor base with Falk Strascheg (FSH) joining a €2.3m round.

FSH took almost half of the round, with the other half coming from existing investors Bayern Kapital, High-Tech Gründerfonds, and Munich Technical University’s investment fund UnternehmerTUM-Fonds and Dr Schulze Holding.
