That's demand driven and organic, at least, and it's not the first thing that comes to mind with hypergrowth, it's just scale.
Instead, I think of hypergrowth as a supply-side attempt to capture a larger market in a highly inorganic way and to also capture the absurdly high valuation that comes with it. Usually through VC.
Virality would be a factor in this too, which is totally demand-side even if there are levers that can be pulled to induce it artificially, but that's getting towards dead internet theory and engagement-bait I think and it's more on the media/consumption side of things.
