Question about applications

[Clement @ Leitersburg Lawn and Garden LLC]

We are looking for an option similar to NextCloud for team 
collaboration. We want to host this on our own on-premise server.
Nextcloud seems way too huge or bulky for our small business...
Are there any other open-source options especially for Debian?

Any suggestions would be appreciated!
