Between Discord and Slack, I think something SaaS companies need to consider is looking at play and how to genuinely integrate play / fun into how they develop product. Both of these huge companies spawned out of video games and I think we are going to see more spawn this way.
I think play, especially at work, isn't discussed or considered enough and can form a strong core of a good product ("focus on the fun rather than the money") [0]. If a product evokes good feelings, especially if it is being used in an otherwise drab 'setting' ("I need to talk to other people"), people will gravitate towards it over others that don't.
I can't think of a person who is overjoyed to use, say, Microsoft Teams but you will almost certainly find people who love Slack or Discord to the point of pushing their leads to use them.
