German drone technology startup Wingcopter has raised a $22 million Series A – its first significant venture capital raise after mostly bootstrapping. The company, which focuses on drone delivery, has come a long way since its founding in 2017, having developed, built and flown its Wingcopter 178 heavy-lift cargo delivery drone using its proprietary and patented tilt-rotor propellant mechanism, which combines all the benefits of vertical take-off and landing with the advantages of fixed-wing aircraft for longer-distance horizontal flight.

This new Series A round was led by Silicon Valley VC Xplorer Capital, as well as German growth fund Futury Regio Growth. Wingcopter CEO and founder Tom Plümmer explained in an interview that the addition of an SV-based investor is particularly important to the startup, since it’s in the process of preparing its entry into the U.S., with plans for an American facility, both for flight testing to satisfy FAA requirements for operational certification, as well as eventually for U.S.-based drone production.

Wingcopter has already been operating commercially in a few different markets globally, including in Vanuatu in partnership with Unicef for vaccine delivery to remote areas, in Tanzania for two-way medical supply delivery and in Ireland where it completed the world’s first delivery of insulin by drone beyond visual line of sight (BVLOS), the industry’s technical term for when a drone flies beyond the visual range of a human operator who has the ability to take control in case of emergencies.
