Have to be careful not to compare how they do business now, with how they did business when they were operating from a "garage". I would assume that they (the co-founders) were essentially their own world-class sales team in the beginning and their reputation now replaces that function entirely.
Like any other consulting, you develop a reputation working on smaller projects and then you start getting approached by larger firms. And if you have a contact on the inside it's also easy to design something on your own and then get a chance to present it to the megacorp.
I've known a fair number of people in the toy design business and it works pretty much the same way. It's just industrial design with a different audience.

Also, once you have their reputation, I bet companies come to them.
