There are no mega-companies because it is not a single market in practice. Language alone splits your market.
It would be like launching your SV startup only in California and not getting the other 49 states for 'free'. For each new state you launch in, there is regulatory burden and language burden, not to mention culture differences affecting UX. Small markets limit growth and reduce ability to raise capital -> ergo the US competitor will almost always win.
