Dilip Modi took over as chairman from Bhupendra Kumar Modi in February last year.
Over the past five years, Dilip Modi has set up the firm's mobility businesses in segments like mobile devices (Spice Mobile), mobile value added services (Spice Digital) and mobile retail (Spice Hotspot).
In October 2010, he was appointed executive vice chairman and in May 2011 as managing director of Spice Global. However, he stepped down as managing director in February 2012.
Spice Mobility, a part of BK Modi Group, has changed its name twice, reverting to its previous name recently. It has been trying to position itself as a mobile internet firm but it still derives a large chunk of its revenues from its handset business.
It has operations spanning India, Nepal, Bangladesh, Uganda, Tanzania, Zimbabwe and Sri Lanka. In December last year, the promoter group said it was looking to delist the firm.
