We use Pharo commercially because it offers us a number of critical competitive advantages: - the superior environment makes development fun; - the short development feedback loop allows us to learn and improve; - open source & cross-platform allow us to make deployment decisions purely on technical reasons; - the talent in the community gives us the guarantee that we can buy our way to a solution if needed; the focus on both research and commerce makes sure that there are good people that continue improving Pharo and that they can stay in the Pharo community after graduating; - the availability of frameworks such as MOOSE and Seaside and the good compatibility with Gemstone allows us to provide better solutions faster.
