Systems for managing profiles (dossiers) of people, groups, companies (+ links to social network profiles)?

Question

CRM

I am looking for web applications for maintaining a dossier on a large number of individuals, companies, their relationship with each other, social accounts. networks. and other entities. In fact, the system should implement the many2many model, where you can arbitrarily create lists (people, groups, companies) and entities in them (names, positions, email, phone, employer, tax number, links, etc.).
A certain admin panel for the Openid database comes to mind, where admins add new users, without any user participation.
Another option is a web interface (without graphs) for the Palantir system.
The list of users of such an interface is 10-20 people.

Answer 1

amoCRM is perfect. There is all of the above (arbitrary lists are tags, you can add custom fields to take into account specific data), it works smartly, for three users it's free. I like it, in general. :)
