Yep, I agree with all of these points. Casper and Capsule also come to mind (both headquartered in New York, probably get lumped into these kind of lists, and probably aren't really tech companies). But there are other ones that "feel" more like tech companies, just nothing quite nearly as big as DoubleClick. e.g. Songza (acquired by Google), Cockroach Labs, Vimeo (acquired by IAC but still operating independently) have not (yet) been mentioned. EDIT: I see Vimeo was covered below.
