DTB traces its roots to the Diamond Jubilee Investment Trust, founded in 1945 in Dar es Salaam to serve East Africa's Ismaili community, which split in 1965 into separate Kenyan, Ugandan, and Tanzanian entities; the Kenyan arm became Diamond Trust of Kenya in 1990. The group is an affiliate of the Aga Khan Development Network, with the Aga Khan Fund for Economic Development holding roughly 16.5% of DTB Kenya, the group's Nairobi Securities Exchange-listed flagship. DTB also operated in Burundi from 2009 before selling its 83.67% stake in Diamond Trust Bank Burundi to a local investor consortium in a deal that closed 31 December 2025, refocusing the group on its three core markets.

The group runs roughly 150 branches across Kenya, Uganda, and Tanzania, with consolidated group assets of around KES 612 billion (about $4.7 billion) as of mid-2025, and offers bancassurance products, including life and medical insurance, through partner arrangements.
