Real-Time Payment Platform for Fintech Startup
What We Were Up Against
A Series A fintech startup needed to build a PCI DSS compliant payment platform from scratch. They had an aggressive go-to-market timeline, a small engineering team, and zero payment infrastructure. The platform needed to process ACH, card, and wire transfers from day one, with fraud scoring built in.
How We Solved It
We assembled a dedicated 6-person team and embedded a payment architect with deep PCI DSS experience. We chose a tokenization-first architecture using Stripe and Adyen as processing rails, with a custom routing layer that intelligently directs transactions based on cost, success rate, and latency. Fraud scoring was implemented using Stripe Radar augmented with custom velocity rules. We achieved PCI DSS SAQ-D compliance in month 3.
