Indimi was born August 12, 1947, in Maiduguri the capital of Borno State, north-east Nigeria. His father, late Alhaji Mamman Kurundu was also a businessman who traded in hides and skins. Indimi attended traditional Qur’anic school as it is the general practice of Muslim communities in the Northern Nigeria. He could not attend formal school because his father could not afford to sponsor his formal western education but still managed to learn how to speak, read and write in.
At the age of 10, Indimi followed his father to local markets around Borno to trade animal hides and skins. In 1963, he became independent and started his own business after he collected 100 pounds loan from his friend Alhaji Umar Tela which he used as a start-up. Eventually, he decided to expand into selling clothes which were imported from Chad and Cameroon.
In 1990, Indimi got oil prospecting license granted by the Ibrahim Badamasi Babangida regime. He established an oil and gas firm named Oriental Energy Resources (OER). Indimi served as chairman and board member of several companies including Jaiz Bank.
