It seems that they outsourced almost everything to different companies rather than taking expertise in house.

SpaceX seems to be doing everything themselves. Amazon seems to be doing a lot but will likely outsource launching of the birds. Wouldn't be surprised if they fly on SpaceX rockets in part....
