If you have an already established business then the strategy would be different and if you are going to launch the same kind of business in India then the steps would be different.

Keeping your words in consideration that you want to grow it, it means you already have such business with you, now the timeline of your business in the market matters a lot. Anyways following things you can do at this stage to grow your business:

Increase your penetration.
Look for other channels e.g. corporate & digital.
If you are premium in the market then launch an affordable product line for other segments as well.
Review your business models, take it to all three models B2C, B2B and B2G.
Optimal utilisation of available resources can also maximise your profitability.

Thanks
