> Ballmer joined Microsoft on June 11, 1980, and became Microsoft's 30th employee, the first business manager hired by Gates
> [Ballmer] left the MBA program at Stanford University
Ballmer is what Marisa Mayer was (or vice versa). An employee that latched onto a rocket. What made the company successful wasn’t them but the founder. By the time you can hire the 10th employee, risk is already greatly reduced.
However his focus on enterprise laid the seeds for 365 and Azure and flourished once Satya made it clear that not everything had to revolve around Windows and Office. I think Gates is also a bit to blame here as I think the story goes that almost every decision that came to the board was shot down unless it meant more windows/office sales
