The Space industry needs propulsion. BETTER PROPULSION.

ion (n.)

1834, introduced by English phycisist and chemist Michael Faraday (suggested by the Rev. William Whewell, English polymath), coined from the greek "ion", neuter present participle of ienai, "go," from the root "to go", so called because ions move toward the electrode of opposite charge.

ienai SPACE was founded with a mission to change the way the on-board electric propulsion market operates. We believe that clients should not be forced to build their spacecraft around a small number of available propulsion products, but that these systems should adapt to the constraints and requirements of each individual mission.


At IENAI SPACE we stand committed to fostering a workplace that champions gender equity, not only because it is the right thing to do, but because it is vital for the success and growth of our company as we explore the vast reaches of space. Gender equity is not just a buzzword; it's a fundamental value that we will uphold at every level of our organization. We firmly believe that diversity and inclusion are essential for innovation, progress, and ultimately achieving our mission of expanding humanity's presence beyond our planet. -> If you're interested to know more, please check out our Gender Equity plan here!


Our goal is to remove entry barriers for the adoption of electric propulsion technologies in the smallest of satellites, providing platform manufacturers and integrators with the tools necessary to understand their propulsion requirements, and the best possible hardware to address them.
