First off, what is Nextcloud?
Nextcloud GmbH is an open source software company with its world headquarters in Berlin, Germany. It's completely FREE and therefore the only cost to you is the "utility" of sending bits & bytes to you from the cloud. Nextcloud is open & transparent for data sovereignty, so you can build your own private cloud for internal communications.. instead of sending messages on Facebook, IG, WhatsApp and others where you can never really 100% know if its coming from people you trust.
Nextcloud makes it easier for a company like Demesto to exist, and while we are a team of programmers, cybersecurity experts and salespeople we can fix the little things but the larger scope of the project and extensions has a massive support base around the world! Because of this open source nature, we can simply become experts with installs, web hosting, backups and maintenence for you and our international clients, anywhere in the world. The burden of new feature development is shared with a giant community, and R&D costs are a minimum so we provide tremendous value at a low cost, with full-support of your install(s).
Open source projects are pretty broad in scope & feature design. The emphasis is on stability, as in we're not a smaller outfit that is constantly moving buttons around on the screen, changing the user interface, or making bug fixes to our own software. It's generally a very stable install and once you get comfortable with your processes its not changing very often.
