Hi.
I can link you up with a global payment processing fintech. Mid market/smb ERp and CRM are being commoditized. The fintech works with these cominies to bolt on the payment opportunity on the AR and AP side. For example a $10m year biz represents $10-$18m in payments. I.E., about a $100 to $200k profit oppty - recurring.
Open sourcing is a good idea - it allows for platform innovation and adoption - while regulated services becomes the profit driver.
