Meet 15 Of The First WhatsApp Employees -- Many Of Them Are Probably Set For Life

Julia whatsappWhatsAppJulia Reznikov was only at WhatsApp for a handful of months so she might not have gotten WhatsApp stock. She joined Federated Media then Google.

When WhatsApp was acquired a few days ago for $US19 billion, it had a fairly small team.

55 people work for WhatsApp; 32 of them are engineers. The rest mostly handle customer support.

We rounded up some of the earliest WhatsApp’s employees on LinkedIn. These people are responsible for creating the fastest growing social network ever. 450 million people use WhatsApp every month.

Many of the early employees were former Yahooers, just like WhatsApp co-founders Jan Koum and Brian Acton.

Which employees did we miss? Leave the names in the comments.

Jan Koum is the co-founder of WhatsApp. He's now a billionaire.

Kung was a former Yahoo engineer-turned angel investor who started advising WhatsApp in March 2009. His LinkedIn profile says he's 'semi-retired.' Maybe now he'll be fully retired.
