The Chief Operating Officer of the Japan-based telecom and Internet giant said that 2015 witnessed huge funding going into start-ups, but it also saw firms being wiped out.
He was speaking at the Startup India event here.
"So now in 2016 you have to sit down and say are these deep discounting models required to continue or is it time for people in this business to start differentiating and start trying to compete on the quality of services to the end consumer.
On the outlook for Indian eCommerce market, the former Chief Business officer of tech giant Google said: "In many of these sectors, I have seen that there is room for more than one player in the market, so hopefully our investee companies and other companies in the same sector would listen to the advice."

Arora said 2015 saw "tremendous" amounts of funding going to a lot of companies.
"But also what it did was that it created a shake-out in lot of the sectors in the market. ECommerce sector has gone from 500 plus companies to probably 10. The ride hailing services have perhaps gone down to two companies," he added.
On a question whether there will still be an appetite for funding in the future, he said earlier due to the low risk profile of the world money was easy to access, people were been willing to give money much quicker to start ups and much quicker to new ideas.
"All that will happen is that great companies will continue to get funded, lot of not-so-great companies will get weeded out. I expect to continue to see funding happening and a market to be there for great ideas," he said.
He further said: "If you find a problem and solve it,
then you and I as a consumer will find nothing better. If you are doing really well, solving a lot of people's problems, you will have no trouble finding the money.
On investment in solar energy space in India, Arora said: "I think it has to do with the vision that Masa (SoftBank Founder Masayoshi Son) had. He decided to focus on clean forms of energy in Japan and I think by extension we started in India. India has a huge opportunity to leapfrog the existing not clean ways of producing energy."
"Of course, the government has done a great job in creating the right auctions, but not particularly great for us people who are bidding at the outside," he added.
In December last year SB Energy, the joint venture firm of SoftBank, Bharti Enterprises and Foxconn, won its first solar project in India at a tariff of Rs 4.63/kWh.
It won the NTPC bid to develop a 350 mw solar power project in Andhra Pradesh, under the Jawaharlal Nehru National Solar Mission at a 25-year tariff of Rs 4.63 per kilowatt-hour (kWh).
On his areas of interest, he said: "The areas where I have been personally interested, in which I haven't seen a skilled solution yet, is that of education. I think with the technological advances, we have resources to reshape it.
