Zoom is interesting. They don't really seem to have done anything particularly novel, they just made a product that works better than the competition. We use Zoom heavily on our fully remote team because it works better than free alternatives like Skype and paid alternatives that we're already paying for like Slack.
It's quite refreshing to see a tech company succeed by just making a better product and expecting that people will be willing to pay for it. They were able to grow so quickly in part because it was relatively easy for people to switch from other video conferencing solutions however. I'm not sure they will be able to build much competitive advantage other than just continuing to be a better product though. If Slack worked just as well we'd happily use it and stop paying for an additional service.
