Analytics services provider Mu Sigma Inc. has appointed its chief operating officer (COO) Ambiga Dhiraj as its chief executive officer (CEO). Mu Sigma’s founder and former CEO, Dhiraj Rajaram, will remain the chairman. The company said that the new CEO will head the company out of Bengaluru, while the chairman will focus on client engagement in the US.

Last year in July, Mu Sigma’s managing director, Ganesh Lakshminarayanan, quit the company a year after joining it, and in March, its chief financial officer (CFO) Atul Bansal left the firm. Mu Sigma is yet to appoint a full-time CFO.
