This would be a horrible investment anyway.
I use Affirm, which is similar. You pay for something kind of expensive - minimum is 100 USD - break it into 3 or 4 zero-interest payments, use a virtual credit card they generate, which is tied to your real credit card or bank account, to make the purchase. Every few weeks, they take a payment from you from their automated process to repay the loan from either your real credit card or directly from your bank account. You pay your real credit card balance every month and viola! you have your merchandise and don't pay anyone any interest. I may be an outlier doing it this way, but I don't see how money is being made except possibly through some sort of affiliate program.
The other way is to take a plan that bears an interest rate that is similar to real credit card rates, which is not a good decision to begin with. That said, it's no different than using a real credit card and having a balance. Those people have always been a high risk, which is why the interest rates are high to begin with. If memory serves, they have been defaulting at an increasing rate for years, so they may have reached a point where those loans are also unprofitable.
In any case, I don't see these services making money. YMMV.
