My wife is from Raipur, Chattisgarh, and I have personally been there a few times in the last couple of years. I have seen the city growing every time I go there and with a population of 4+ million, the opportunities for entrepreneurs are growing as well.
Education – Though there are now a lot of top schools in Raipur, there is a gap in the Private college space there. Most students leave for other cities (Pune, Delhi etc.) to pursue higher studies and end up getting jobs there and settling there.
Retail – The purchasing power of people is going up and retail probably holds the biggest potential. All majors Brands are slowly establishing their presence in this fast growing market. Even premium brands are now getting attracted towards the city.
The Services Sector
Entertainment & Wellness – The city needs more outlets like gyms, restaurants, bars etc. catering to its young population.
