What Whatsapp Did To Get It's First Million Users. I wanted to first ask how they got their first 1,000 users but lot's of startups have done that. This question can only be answered by the founders, early employees, investors and more importantly the early adopters. I'm sure there is no magic pill and they done whole bunch of right things, which combined together gave them the explosive growth. This tip pit could be very useful for, all the rest of us startup founders.
