Key Takeaways:

  • Whisper Aero raised $32 million in Series A funding to develop and scale its innovative electric ducted fan technology.
  • Their core technology achieves ultra-quiet operation by shifting noise frequencies to the inaudible ultrasonic range, without sacrificing efficiency, and also provides 20% greater efficiency compared to other ducted fans.
  • The company is initially focused on the defense sector with existing contracts, but envisions future applications in commercial aviation (drones, eVTOLs) and consumer/industrial products.

Whisper Aero is taking a page from Muhammed Ali’s book.

Last week, the Crossville, Tennessee-based startup raised $32 million to help create aircraft in The Greatest’s image, capable of floating (flying) silently like a butterfly, and stinging—or in this context, delivering high efficiency—like a bee.
