> If you treat other markets as being cookie cutter versions of your own market, you're going to fail.
This is a critical insight that I've seen missed more than once by business leaders.
For a time I worked for a company headquartered in London. They did business loans. They tried to expand to Germany, The Netherlands, Spain, the US, and Canada. At every point they encountered new technologies and a fundamentally different set of payment institutions.
It's not just payment institutions that are different, though. You've got a whole different regulatory apparatus, credit institutions, supporting data institutions, and consumer behavior patterns. I've run into major differences in culture and symbolism and more.
You need to account for all of it in even figuring out if expanding into a country is a good move. Then you have to puzzle out what you have that you can adapt and what you need to build fresh for this new market.
It's often easy to assume that the next market over is just like yours. As you say, this is often dangerously untrue.
