While the VC investments and rise of so many startups is exciting, I am still worried if it is sustainable or everyone is just riding on the VC fuel. Most of the startups, are consumer based companies, many of which, have followed the American counterparts, and to gain market share, they are not worried about spending money like it is endless. Take an example of "Lenskart", which will send an optician to your doorstep who will do eye-check for you @ Rs. 50 ( < $1 ). Not to mention, the sheer number of promotional and branding campaigns they have been running.
I believe not every company is like that, but the startup scene in India is more or less, a gaining-user-share game. In pessimistic future, where these startups would be relying on the last pennies of their funding, I am not sure if they would be able to sustain if they start pricing the things they sell at a price to make a profit, since the Indian consumer finds these offers, the major reason to use the app.
It would be good if the startups also tilt towards actually making products, like VWO, Browserstack and ours[1]. Although, I am aware, that question like, "How the heck that will make money?" has been proved to be pointless at many times in history, if you think of Facebook / Google but I believe eCommerce companies find it hard to grow profits quickly unless they are inventing a new business model (AirBnB, eBay, Alibaba).
