The article starts with some interesting data but instead of analyzing the data to identify tangible, shared characteristics of $1B exits, it devolves into a generalized, vacuous argument that boils down to (1) be in it for the long-haul, (2) work with visionary/tenacious teams (whatever that means) and (3) have founders with strong product sensibilities.
In short, this doesn't really provide useful guidance on how to build a $1B consumer tech company.
