Zephalto, low carbon space flights in stratospheric balloon

Our mission To give the best view of the Earth you need to change your horizon
How? By redefining the standards of space flights through a new access to the stratosphere in 2024, 25km away from Earth
What? Zephalto develops low carbon space flights in stratospheric balloon. We design the experience of the Overview Effect for voyagers and build the first observation platform 25km away from Earth (15km above the planes)

Supported by the French space agency (CNES), Zephalto was launched by Vincent Farret d'Astiès in 2017, and our team of 25 already has some great achievements:

  • We have already flown several innovative prototypes with pilots on board
  • We are supported by the European Space Agency (ESA), incubated at HEC and Station F, and benefits from strong support from the Occitanie region, Airbus Development and BPI
  • We have been selected as one of the 10 future European aerospace unicorns by SpaceFounders
  • Strong investors and an active ecosystem of expert partners
  • Our workshops in Toulouse for the Research and Prototyping teams and our offices in Paris (Station F) for Business Development and Marketing
