#4 Mark Pincus

Zynga

Zynga was once the most popular tech company in the world, anticipating an IPO valuation of $15 to $20 billion. The social game maker proved true to the expectations as the share values rose almost double from just $9 to $16 in just four months after the IPO. It put the company worth $7.4 billion, which made Mark Pincus, the CEO, worth around $1.1 billion as he owned 67 million shares.

Moreover, Pincus held 0.5 percent stake in Facebook, which was at one time valued at $425 million. This made Pincus’s total value to be above i.5 billion.

But everything happened faster than expected. Zynga’s stock started to slide, and after a short time, it began to fall. By June, Zynga lost over 80 percent of its value. The stocks began to trade around just $3, which gave a $2.4 billion market capital to the company.

Things were worse with Pincus. His value of shares has dropped from $1.1 billion to just $200 million. Adding to it, the Facebook shares he held too dropped its value to almost half, making Pincus from a billionaire to a millionaire. After a total loss of $1.113 billion just in three months, Pincus’ worth stands at $425 million today.
