Despite Sun Li and other entrepreneurs' confidence, the O2O market is still in its infancy with a lot of startups dying every year, says Sun Mengzi, from Analysys International.

Some O2O companies pose a threat to traditional stores, while others help boost the sales of brick-and-mortar businesses with Internet technology. But there is no firm that has completely reshaped its traditional businesses.

"There are security concerns with such home delivered services. There is no regulation to guide their development. And many startups' models are easily copied," the analyst says.

Hou from Momoda says he is going to effectively "burn" the investment his company secured and cover more users in 2015.

"You need to stay ahead on everything. Be the first one to get investment, be the first one to expand to second-tier cites ... Otherwise you will die or be taken over by the largest player," he says.

"There is no room for second best in the O2O market."
