Having worked as a teacher, she set up 17000 ft Foundation in order to improve school conditions in remote villages in Ladakh and Sikkim.

Sahu worked in the corporate sector in the United States for nine years before moving to Gurgaon and becoming a teacher at the Shri Ram School in NCR Delhi, teaching mathematics and computer science.

[1][2][3] In June 2010, she went on a solo trek in Ladakh and when she experienced high-altitude pulmonary edema she stopped to recover at a remote village.

Since there were no books in Bhoti, the Ladakhi language, in 2015 the foundation funded translations and supplied 21,000 storybooks.
