What sponsor banks actually look for in fintech due diligence (and what kills deals)
I spent years reviewing fintech compliance programs as a Federal Reserve Bank Examiner. Here's what actually matters when a sponsor bank's BSA officer sends you that 47-item due diligence checklist.
The three things that kill deals:
1. A BSA/AML program that looks like it was written by a lawyer who's never seen an examination.
Banks don't want theory. They want evidence of a functioning program — a designated BSA officer, a written risk assessment calibrated to your customer base, transaction monitoring with documented tuning rationale, and SAR procedures that someone is actually following. A policy document without operational evidence fails.
2. Vendor management that stops at contract signing.
Your bank partner is now responsible for your third-party risk too. They need to see that you've assessed your critical vendors (KYC provider, payment processor, fraud tool), documented ongoing oversight, and have a plan for when one fails. "We use Stripe and Persona" is not a vendor management program.
3. Incident response that's theoretical.
The bank will ask: what happens when you have a potential OFAC hit at 11pm? If the answer is "we'd figure it out," the deal stalls. You need documented escalation procedures with defined roles and a clear SAR filing path.
What actually moves deals forward:
A compliance program organized the way a BSA officer reviews it — not by topic, but by regulatory obligation. OFAC screening with testing evidence. CDD/EDD with documented risk tiers. A training log proving your team is operationally compliant.
The fintech founders who close sponsor bank deals fastest aren't necessarily the most compliant. They're the most prepared to demonstrate compliance quickly.
