I've wondered the same. Back when Antrhopic seemed like a niche alternative to OpenAI, I signed up for an account. Now that my company is using it heavily, I tried to change the account owner to on of the executives, and apparently that's not possible! It's also not possible to create separate work/personal accounts unless you have two different phone numbers.

There's a confusing disconnect between "we have this magic box that can write all the software we'd ever want" and their lack of basic account management functionality.

(Not really. That disconnect is because of something mature software engineers have known for decades - the bottleneck has never been the code)
