Is it modeled strictly per-user or is there any notion of an "organization" similar to Github? It's hard to imagine a business having to manage paying for a bunch of individual accounts so they can have access to the company's private repo.

Organization accounts are coming soon:

  Currently, private packages are only available for individual users, but support for organization accounts is coming soon. Feel free to create a user for your organization in the meantime, and we can upgrade it to an organization when support is here.

NPM Enterprise is a potential solution. You have to host it yourself, but it gives you namespaced modules and the option of selectively mirroring the public registry.
