Ok I gave it a third chance and I think the problem is that you don't define team communication, you say communication and the first thing that pops in my head is hangouts, skype, facebook messenger, whatsapp. Then the second problem is I read about the companies and...:Because messaging is such a broad category, we're going to focus on software that facilitates team communication and within this group, the free to use options. In short, this app roundup is for startups, small businesses, and anyone looking to optimize team communication without spending any money.
Ok, and what does it do?? You left me at square 1, and I'm not quoting the rest of the text but it says nothing, then the video talks about yeah, lets communicate, but how, why, what?Slack is the heavy hitter of the group with a valuation of over $3 billion. Their main clients are big companies that used to rely on the previous generation of SaaS solutions from Oracle and others. That said, Slack is very polished and great for any team regardless of their size.
Ok, and what does it do??
I think this is the main part that was skipped, that believe it or not is not mentioned once not in the article, not in the description of the services nor companies, not even in the videos.The idea is that all communication (chat, images, files sent) is centralized, async, backed in the cloud, cross-platform, permissions can be managed to different users, and so on.
