Mastodon instance for businesses, orgs and side projects?

Are there any Mastodon instances dedicated to profiles set up for businesses, organizations, NGUs or side projects? Twitter is one of the to-go places to find news about many companies and orgs, but I haven't found anything comparable in the Fediverse, aside from more general tech-centered instances.

Big companies might set up their own instance, but for most it's probably total overkill to maintain their own server.

Personally, I have some side projects with dedicated social media profiles, so that their users can follow the project/site itself, instead of following me as the creator. Some have a Mastodon.social profile already, but I would like to have a dedicated place for them.
