Well... An IT startup should have no need of NexCloud/O365/Google suite and so on, simply because techies know how to share files and produce documents in way much better ways.

Staten that, as a POOR solution to collaborative works on documents NexCloud/O365/Google suite might be "good enough" for some, NextCloud is not on par, but near, the burden for IT is simply the fact these products are monsters alone, essentially impossible to really knows entirely in codebase terms, complex to heal when trouble happen etc.

So yes NextCloud could be used in professional settings, and owning their own infra is better than living on someone else computer, but the real point is if your employees really need such tools/paradigm or not. Someone in IT could collaborate with a shared repo, notes, makes slides in org-mode and so on. Someone much less skilled could still use BookStack and alike. Only end-users already trained on office-like stuff could like these monsters.
