Sceye

Sceye is an aerospace company that describes itself as a leader in high-altitude platform systems (HAPS), building solar-powered airships designed to remain in the stratosphere — between roughly 60,000 and 65,000 feet — for months to a year at a time. The company was founded in 2014 by Mikkel Vestergaard Frandsen, a Danish humanitarian entrepreneur previously known for Vestergaard and LifeStraw. Although the company is characterized as Swiss, its headquarters is located outside Albuquerque, New Mexico, in the United States. Sceye's core product is a stratospheric airship platform that uses flexible solar arrays to generate power during the day and high-density batteries to operate at night. The platform is designed to hold position over an area of operation for extended periods, even in challenging wind conditions, and to carry large payloads beneath it. The company chose the airship form factor over balloons and fixed-wing aircraft because it allows persistence over a location while lifting and powering far more payload than alternative platforms. Sceye positions its technology around two main applications: connectivity and observation. On the connectivity side, it aims to provide direct-to-cellphone broadband service from the stratosphere, replacing ground infrastructure at substantially lower cost and helping to connect unconnected populations. On the observation side, it offers earth observation capabilities including real-time quantification of greenhouse gases, prediction of natural disasters, monitoring of ground elevation, plant health, soil and mineral composition, and other environmental data. Sceye emphasizes that its platform can carry multiple sensors simultaneously, enabling a comprehensive fusion dataset of the Earth. The company's engineering team combines expertise from America's Cup sailing, aerospace, and advanced academic research. Sceye operates as a private company and continues to develop and test its HAPS platforms with global partners, with a mission to connect and protect the planet from the stratosphere.

Sceye was founded in 2014 by Mikkel Vestergaard Frandsen. Before founding Sceye, Frandsen established himself as a humanitarian entrepreneur through companies including Vestergaard and LifeStraw. Vestergaard distributed more than 1 billion insecticide-treated nets, helping reduce annual malaria deaths to less than half, while LifeStraw's water filter technology contributed to the near eradication of guinea worm and provided clean drinking water to more than 11 million children. This background in material science proved crucial for Sceye as the company developed novel ways to retain helium, store energy, and build its stratospheric platforms. Sceye's development has been built on a meticulous iterative development and testing process combined with extensive flight experience. The company chose the airship form factor over balloons and fixed-wing aircraft because it allows the platform to stay over an area of operation for extended periods while lifting and powering far more payload than any other platform. Sceye's engineering team combines expertise from America's Cup sailing, aerospace, and advanced academic research. The company has focused on creating the first platform designed for sustained flight in the stratosphere, operating between 60,000 and 65,000 feet. Its HAPS are solar-powered during the day and battery-powered at night, avoiding rocket fuel used by satellites and single-use plastics used by balloons. Sceye works with global partners on its mission to connect and protect the planet from the stratosphere, pursuing both connectivity (direct-to-cellphone broadband) and earth observation applications.
