multiple revenues always the key to survival. you can't be a monoline service provider anymore. also, to reduce risk in this space, encourage broker's to build a well rounded portfolio with several companies not just one. Some ISO's who built 80% of their book with past funder's got crushed when they stopped funding or went out of business. I would say try and keep the rule to maximum 10% with each funder to mitigate risk of a company going under, being bought, or becoming insolvent. historically, the business has had it's swings and some have had to learn the hard way.
