B2B SaaS MVP for NYC Fintech Startup — 7-Week Launch
Devs & Logics built a production B2B fintech SaaS MVP for a startup in New York City, including multi-tenant workspaces, Stripe subscriptions, admin onboarding, and exportable audit logs—launched in seven weeks on Vercel with PostgreSQL.
A Manhattan fintech founder needed a credible B2B SaaS product for enterprise pilots—not slides. Devs & Logics delivered a multi-tenant MVP with billing, role-based access, and audit-friendly logging in seven weeks.
The challenge
The NYC team had LOIs from two pilot customers but only a Figma prototype. They needed SOC2-conscious patterns, team invites, usage-based plan tiers, and a dashboard finance teams would trust during demos in Manhattan and remote calls.
What Devs & Logics delivered
- Scoped MVP around tenant onboarding, team invites, and core analytics dashboard
- Next.js 15 + TypeScript with server-side validation on all money-moving flows
- PostgreSQL multi-tenant schema with organization-level isolation
- Stripe Billing for tiered SaaS plans and customer portal
- Structured audit events for security questionnaire conversations
- Preview environments for each pilot customer during NYC sales cycle
Outcomes
- MVP live in 7 weeks from signed scope
- Both pilot customers onboarded within 21 days of launch
- Used in live enterprise demos for a $1.2M seed extension process
- Documentation package accelerated SOC2 readiness discussions
