ESEN, which operates in the fields of aviation, space, defense and security, was established in February 2012 in partnership with US-based Sierra Nevada Corporation (SNC).

The Sierra Nevada Corporation, led by two innovative business people, Eren Özmen and Fatih Özmen, has achieved significant successes in space systems, commercial orbit transport, mini satellites, energy, tele-medicine, and nanotechnology. In order to ensure effective participation of Turkey in the developments in the field of aviation, space and defense, they established ESEN company and started their activities in Ankara.

ESEN continues to work on innovative projects in METU Technopolis with its result-oriented team that follows technological developments.
