Rajnish completed his P.G.D.M from IIM (Ahmedabad), after which he worked with American Express Bank in a variety of roles and locations (Mumbai, Singapore, London) for 17 years. He left the Bank as a Senior Director in 2006 and returned to Mumbai to work in the social sector and initially joined Aangan, an NGO which works with children in state run children homes.
In 2008, he co-founded (along with Madhusudhan Menon and Nachiket Shelgikar) Micro Housing Finance Coproration Limited ("MHFC") to provide housing finance to lower income households (mostly from the informal sector) in urban India. The promoters believe that one of the issues stalling the development of low income housing is the lack of finance available to lower income families (especially those without documentation to prove incomes) to buy such homes and hence set up MHFC to specifically address this gap. Over the last 5 years, operating in 5 major states, MHFC has sanctioned home loans aggregating about Rs 150 cr to about 3500 financially excluded families. The company has not had any NPAs till date.
Rajnish is also on the Justice Dhanuka court appointed committee to look into the infrastructure of Mumbai municipal schools, and the Boards of Aangan and Ummeed (an NGO which helps children with development disabilities).
