Lessons for a startups: More features doesn't mean more market share!

Can't say. I feel the Brand name plays a very great role, when it comes to getting a market share. that is what i read in a "brand management" book. And in front of Brand, features don't matter much.

"keep things simple" is the key I believe, take any successful start up , Facebook, simple and sober interface, no flashy designs, just login and you will see, what you really want to see and i.e comments on your status

I have not used others but weChat, I liked the features of this app, but weChat requires many clicks in order to send message, but with whats app, it just requires one click nothing else; interface that even a normal user, who is using smart phone for first time can understand it.

Same goes with my clients, if a certain feature they request, requires more than 2 clicks, they will just say "Drop it, I don't like it".

Moral of story: Focus on Your key idea for which you are developing a certain product

As as you say ,
some messaging apps like Hike have introduced better features than Whatsapp have been growing well and the introduction of free recharges and offline free messages had made many of my friends to switch from whatsapp and wechat to "HIke" but my view is that the reason for whatsapp success is that it came first and enjoys benefit of it as many of them don't want to do install all things and confuse themselves.

Not always the simple is the best but in the mentioned comparison, I would say its the simplicity of whatsapp which made me stick to it despite its fancy competitors.

Whatsapp is kinda pioneer to this business and before anyone else could enter, it had already made a good share in market. Its like chicken and egg problem for others. But yeah, if whatsapp will just stop improving it won't take much for it to go down. We've seen what happened to Nokia. The word which was synonym of a cell phone has became in-existent in pretty much overnight.

Kaustubh KatdareDo we have a lesson for all the startups here? Do more features mean you get more market share? What's your opinion?

Startups should deliver the basic value for money product that is rugged, user friendly and tough.
That is what a CEan startup up to now with his telemedicine product. With a shoe string operation, he is after delivering a high grade product with an advanced on board expert system without any unwanted 'fair and lovely' features. A no nonsense product.
I wish him all success.
