All the ones where the idea was to "just start something, grow grow grow, then figure out monetization later" is wild to me.
E.g. reddit. It worked. CEO is rich, site is still online. Somehow they got investors probably, presumably.
I get not having profit. I get not having income, if it's in some prototype phase. But having no plan or idea whatsoever for how to monetize and still getting VC? Wild.
