summary

Growth hits 430 million active users (from 350M to 400M to ~430M in weeks), tiny team of ~50 people with 25 engineers and ~20 support staff, and the system handles roughly 50 billion messages a day; the app is free to download but uses a low‑fee service model, encrypts traffic between phone and server, stores minimal user data (phone numbers only), refuses advertising, and aims to be on every smartphone worldwide.
