Ask HN: How can a product like ClickUp grow so fast (or even grow at all)?

When ClickUp launched in 2017 there were dozens, if not hundreds of task management services already. How can a product like this, in a market so saturated, convince businesses to change where they do their work and start paying for it, to the point where it has become more coveted than all of its competitors? the product didn't seem particularly unique, so what's the deal with something like that? how did it make itself visible? is this still doable these days?

I'd compare it to launching yet another chat app for businesses and taking all of Slack customers, for example. Does that even make sense?
