Portuguese turbine-sensor startup Fibersail lands Series A from Dutch family office
What's the deal? FibersailDealroom has a profile for this one. Try Dealroom →, a Portuguese startup making sensors for wind turbine blades, has closed the first tranche of a Series A round led by a Dutch family office. Founder and chief executive Carlos Oliveira said the priority now is to “ramp up deployment.”
What's the endgame? Fibersail's technology gives turbine blades a form of real-time awareness, tracking how they bend and behave in operation. The fresh capital is aimed squarely at scaling how widely that technology is installed.
