Accion Systems

Accion Systems is a provider of in-space propulsion systems for satellites based on proprietary technology developed at MIT.

Accion Systems is pioneering scalable electric propulsion technology that will completely transform what spacecraft can do in and beyond Earth's orbit.

Accion Systems was founded in 2014 by Natalya Bailey and Louis Perna. The company is headquartered in Charlestown, Massachusetts.


Accion’s in-space propulsion technologies optimize scalability, performance and efficiency. Accion’s flagship product, TILE, uses proprietary ion electrospray thrusters, bringing electric propulsion to satellites of all sizes and redefining in-space capabilities.


Accion was recently one of fourteen companies selected by NASA as part of its Tipping Point partnership for Moon and Mars technologies. Accion’s in-space propulsion system will be used on replicas of the MarCO CubeSats, NASA’s first CubeSats that traveled on an interplanetary mission.


Accion Systems is backed by Boeing HorizonX Ventures, Shasta Ventures, U.S. Department of Defense and NASA. The company raised $11M in a Series B financing on Feb 04, 2020. This brings Accion's total funding to $36M to date.
