News: Owns 4% of the social media giant.
In a Tweet praising new Twitter CEO Jack Dorsey for his recent decision to cut back the workforce at the social media giant, Ballmer revealed that he had bought 4 percent of the company.
"Good job @twitter,@twittermoments innovation, @jack Ceo, leaner, more focused. Glad I bought 4% past few months."
The praise comes after Twitter founder Dorsey, having recently been appointed permanent CEO, sacked 336 employees in an attempt to create a "smaller and nimbler team".
Most of the job losses will apparently come from the Product and Engineering departments at the company.
