Few interesting numbers from sequoiacapital.tumblr.com and a quote:
32. Even by the standards of the world’s best technology companies, WhatsApp runs lean. With only 32 engineers, one WhatsApp developer supports 14 million active users, a ratio unheard of in the industry. (WhatsApp’s support team is even smaller.) This L E G E N D A R Y crew has built a reliable, low-latency service that processes 50 billion messages every day across seven platforms using Erlang, an unusual but particularly well-suited choice. All that, while maintaining greater than 99.9% uptime, so users can rely on WhatsApp the way they depend on a dial-tone.
We know very few about their architecture.. What we know is that they care really about their work and… stay focused. For a GOOD product. A software, an App, a startup is not a nice wrapped package or an octopussian business model.
So is not only about getting things done.
Good luck 32! 🙂
