Tamba Lamin

Tamba earned his first wage teaching mathematics to his classmates in secondary school in Sierra Leone. Teaching has run through everything since: SAT preparation, computer skills for small businesses, graduate students as an adjunct professor at Pace University (2014–2020), and architects and delivery teams inside one of the world’s largest professional services firms.

His unnamed home business began in 2000. In 2001 he founded Memaa Information Technology (MIT), which registered as LAM-TECH Consulting Enterprises on 8 May 2009 and rebranded to TpISENT in 2018. TpGROUP (SL) Limited was incorporated in Sierra Leone in 2024, with Amadu Massally and Aminata Kondeh recognised alongside him as group co-founders. In New York he earned three degrees in four years while working full time, including an M.Sc. in Information Management from the Polytechnic Institute of NYU (now NYU Tandon), top of class.

At Accenture from 2015 he established digital experience centres of excellence in Mexico, Costa Rica and India, and went on to lead a 1,500+ practitioner global practice as Global Practice Lead for the digital experience platform portfolio and North America Practice Lead at Accenture Song. For the last three years agentic AI has been the centre of his practice.

As CEO of TpGroup he led The Eco-Living Oasis at Kent from first drawing to opening: ground was broken in November 2021, and it opens on 14 November 2026. He is the founding president of Sierra Leoneans in Technology.
