SpaceX is creating a new system from scratch. But, at the end of the day they are not a software company so in 10 or 20 years you can expect them to be hiring the same consulting company's for internal projects that Lockheed Martin uses.
In the consulting world product is irrelevant you serve large organizations and the problems they develop over time. While they are young Google, Facebook, and SpaceX don't have a lot of the internal cruft that consultants exist to deal with, but I can guarantee they are creating it right now.
Amazon EC2 and GMail are probably the best examples of direct completion with traditional consultants by start-ups. But again it's all about the organization and and not what the organization produces and non of them started by focusing on that stuff. All large companies need email and don't necessarily know how to make is safe, secure, and salable.
PS: By software company, I am talking about mindset. GM creates a lot of software, but it's not what upper management focuses on day to day.
