From this article in Forbes:
"And he’s not immune to mistakes. [Investor's] $3.6 billion 2015 acquisition of San Francisco-based digital network tracker Riverbed Technology is currently struggling because of slowing sales and too much debt."
Also from the article:
"There are also layoffs. Those can total as much as 10% of the workforce, for which [Investor] doesn’t apologize. 'In order to realign the business and set it up for big-time growth, you first need to take a step back before you take a step forward. It’s like boxing,' he says."
Riverbed has laid off, what, over 50% in the last four years with no end in sight? Ouch. I wonder how much better things would be for everyone if they had laid off the right 10% in the first place!
