From MVP to Series A in 18 Months
How we helped a fintech startup build a compliant payment platform that scaled to $2M ARR and secured Series A funding.
§ 01 — The Challenge
What we walked into.
Our client needed to build a PCI-compliant payment processing platform from scratch while competing against established players. They had 6 months of runway and needed to prove product-market fit quickly.
- 01No technical co-founder, limited development resources!
- 02Complex regulatory requirements (PCI DSS, SOC 2)!
- 03Need to integrate with multiple banking APIs!
- 04Aggressive timeline to secure next funding round!
§ 02 — The Approach
How we shipped it.
We implemented a phased approach focusing on compliance-first architecture while rapidly iterating on user experience.
Iteration (Weeks 5-12)
- User onboarding optimization
- Multi-bank integration
- Automated compliance reporting
Scale (Weeks 13-24)
- Performance optimization
- Advanced fraud detection
- White-label capabilities
§ 03 — The Results
What it shipped.
The platform launched on time, achieved compliance certifications, and exceeded growth targets.
“Drexus didn't just build our product—they built our engineering culture. Their team became our team, and that foundation enabled us to scale rapidly after their engagement.”
