Understanding the starting point.
Who They Are
NovaPay is a Series A fintech startup based in Austin, TX, building a real-time payment orchestration layer for mid-market e-commerce brands. Strong product vision, 6-person team, zero bandwidth.
The Situation
Their founding engineers were stretched thin maintaining legacy integrations. They needed a net-new platform - multi-PSP routing, real-time ledger, merchant dashboard but couldn't pause revenue work. Two previous agency engagements had stalled.
Why Devlyn
NovaPay's CTO heard about Devlyn's AI-augmented delivery model through a YC founder network. The deciding factor: a guaranteed production-ready MVP within 6 weeks, backed by a senior-only engineering pod with fintech domain expertise.
Every month of delay cost $40K and growing merchant churn.
NovaPay needed to ship a production-grade payment orchestration platform before their Series B runway pressure kicked in. They'd burned through two agencies and couldn't afford a third miss.
Before Devlyn
After Devlyn
3-month hiring pipeline with no senior candidates in sight
Two failed agency engagements totaling $95K in sunk costs
Manual payment reconciliation causing 12+ hours/week of ops overhead
Dedicated 4-engineer pod onboarded in 48 hours
Production MVP shipped in 5 weeks at 40% lower cost
Fully automated reconciliation engine processing 50K+ txns/day
AI-augmented engineering, delivered at velocity.
How We Engaged
We started with a 1-week technical discovery sprint - mapping NovaPay's existing infrastructure, payment provider contracts, and merchant requirements. By day 8, a dedicated 4-engineer senior pod was shipping code against a locked-down 5-week roadmap with daily async standups and weekly demo sessions.
How AI Accelerated Delivery
AI-generated test suites cut QA cycles by 60%, catching edge cases in payment routing logic that would have surfaced weeks later. Boilerplate generation for API integrations reduced PSP onboarding from 2 weeks to 3 days per provider.
