Examples of such tools are:
-slack.com
-bitrix24
-Dropbox business
-Monday.com
-Trello
-Samepage
-G suite
Github.com and similiar sites can be seen as collaboration tools for developers.
It is typical for such pages that the user receives a subpage in the form "portal.com/user" or "user.portal.com". Some collaboration tools offer to create websites or news for the public.
These pages then have a URL such as www.portal/user/news.html. Search engines will not list such websites.
You would have a better chance for a listing at Google, if the website would be called company.sbs.
It is very difficult to remember websites like www.portal/user/news.html. If such a collaborative website would be called e.g. company.sbs, everybody could remind it.
Such a name is extremely memorable. The memorability of a website's domain is the key of the website's marketing.
