I was definitely talking about the first category (though not necessarily public only; AFAIK there are some [many?] private companies that fit that profile). I agree that those revenue multiples are high, though I'm not sure I would refer to them as "sky-high". Who knows what kind of numbers we will see in the future ... ;-)
For private companies at around $1Mn-$3Mn ARR growing sub-20% YoY there are very few buyers in the first place.
