We use Nextcloud for company-file-management, personal work-documents and for collaborative work (through collabora), organize our #TODOs, that are not covered by the Bugtracker. Existing solutions either were very expensive ( Google Drive ), missed a lot of features ( Trello ) or were pretty much overloaded with features ( Wekan within Sandstorm ).

That made Nextcloud ud our natural fit for our company management and we're convinced of its integrations and flexibility.
