We will first start in Canada. Regulations are different in every country. If we could we would target the world, unfortunately we cannot afford it for the moment.
I can see why it's a trouble to let non-Canadians borrow; But what about investing? What's the legal trouble with letting foreigners invest through the internet? Isn't it just like opening an internet store, except the product is "Colektivo credits" or something?
there are many problems, one of them is money laundering, like criminals who could use the service to get "clean" money. which means Colektivo need to track individual investors and make sure they are in Canada.
Actually nothing keep Colektivo from lending to foreign companies, but it's another thing to accept foreign investors.
