The Challenge
Compliance without compromise
Catalist needed PCI-compliant payment infrastructure without hiring a dedicated security team. Legacy banking APIs were slow, brittle, and poorly documented. Every vendor required months of integration work and separate compliance audits. The team needed a way to move fast without cutting corners on security.
The Solution
EEv3 as the compliance layer
Built on EEv3 with ee.billing for Stripe-powered payments, ee.auth for KYC flows and multi-factor authentication, ee.compliance for automatic audit trails and regulatory reporting, and ee.database for a real-time transaction ledger. Every compliance requirement was handled by the platform — the Catalist team focused purely on product experience.
The entire platform launched in 6 weeks. No security hires. No compliance consultants. No separate audit processes. EEv3's built-in compliance faces handled everything from PCI-DSS to SOC 2 reporting automatically.
