I guess he meant wechat/qq,kakao and line that are dominant in other countries. Whatsapp is impressive though.

Most people seem to use LINE from what I see, living in singapore and traveling around.

WhatsApp user base is insanely impressive but it isn't even no 1 in the country Ycombinator is based in. FBM is. Then it also isn't no 1 in obvious countries like Korea Japan China Taiwan Vietnam.

While I agree that Whatsapp is the dominant chat app in Asia, it's not number 1 everywhere.

Notably - as you mentioned - Wechat in China, but also Kakao in Korea, Zalo in Vietnam and Line in Japan and Taiwan, where very few people use Whatsapp.

Agree with this one. Only local startup can compete whatsapp. Asia, rusia and africa.

In my experience, most people in Taiwan use both Whatsapp and Line

WhatsApp is #1 in 55% of countries. It loses out to Zalo, Line, imo, Facebook Messenger and Blackberry Messenger in various countries.

I'm pretty sure you made up every claim you just wrote. Why would you bother doing that?

Think he meant within Asia

It's not true within Asia, either. Japan, Vietnam, Korea, Malaysia...WhatsApp isn't #1 is any of those places and neither is WeChat.

I never said anything about WeChat?
