Yea, Cupid media‘s “33” sites like MexicanCupid, UkraineDate, etc is a great example of country specific branding while a great deal of software/ IT infrastructure could be shared.

But it’s also common in many industries to have 3rd party software companies offer various levels of customizable software that can look very brand specific while being nearly identical. Sometime it’s obvious like with Android, but no car company wants someone else’s look and feel let alone logo in their infotainment system. So it’s not alway obvious how distinct everything actually is under the hood.
