[abfunders]

For those that have been in the industry long enough, when all we had were CC splits in 2007 - 2008, then some ach products came out in 2009 - 2010, they were set up exactly like this. Merchant signs up via decision logic, or provides view only access to their bank account or any other type of access for the funder to see daily deposits, then funder debits the agreed upon % based off of the daily rev, just like a CC split but all rev is included.

Decision Logic or Plaid
There's not a dearth of solutions like that in the market today that just weren't there 13 years ago.
Also, I imagine that investors liked having the set daily payback to know that 6 months means 6 months.
