Earlier quoted context omitted.
"You'll only know if you're inside the company" rings true. You'll never know how easy/hard it is to find clients as a consulting company as big and probably as expensive as Pivotal. Maybe at some point the business model isn't as good as it could have been. Maybe potential clients balked down. Maybe the sales cycle is long enough that the profit has become marginal.
Consulting is also a real PITA management-wise. You have to map billable hours to available resources, sometimes even unavailable resources you haven't even hired yet. That's really hard to scale.
Managing human-resources to make every single second profitable is hard.
Not to mention the varieties of technology out there: some people use Erlang, Haskell, Node.JS, bunch of NoSQL, Python while Pivotal is more known as the Agile, Ruby, and probably Java to some extend.
Also, we don't know what the startup owners/CEOs want; they could come to Pivotal with unreasonable requirement: cloud-scale or money back guarantee?
