The subject line of the e-mail was like every other come-on that hit Jan Koum’s in-box in the spring of 2012. He was pounded daily by investors who wanted a piece of his company, WhatsApp. Hatched on his birthday, Feb. 24, 2009, WhatsApp was emerging as a global phenomenon. Some 90 million people were using it to text and send photos for free. No social utility had ever grown as fast. Facebook had only 60 million by its third birthday. And at the time close to half of WhatsApp users were returning daily.
Koum looked at the e-mail sender: Mark Zuckerberg.
I’m guessing this isn’t how most multi-billion dollar acquisitions occur.
