app was buggy and crashed • Apple launches push notifications in iOS • Koum adds push notifications to WhatsApp • Users use the change in status to ping each other—the notification becomes the message

The Early Pivot • Koum
realizes he’s built mobile messaging and pivots from address book status manager to messaging app • User base explodes to 250,000 with pivot

Remarkable Focus on Product •
Laser focus on core user experience—no ads, no games, no gimmicks • No user acquisition spend • Focus on maximum utility • Focus on broad adoption and interoperability, not just smartphones

Koum’s desk.
