Microsoft, Amazon, Google, Meta, OpenAI, Intel, Nvidia, AMD, Netflix just to name a few.
very few companies sign an agreement with "Apple". You sell a good or service to a single person, small group or maybe a department. There are countless customers this size, the difference is do they treat you like they are the embodiment of "Apple"? We have lots of big, well-known clients and for the most part they do not.
I mean, Apple does have a procurement process. If you're selling at the large team / department level or up (i.e. not individuals within Apple), you're dealing with "Apple" at least for the sale through security and contract reviews, etc.
