The Problem

A startup founder validated a concept with a Notion template and 200 waitlist signups. Needed a real product: multi-tenant, per-org billing, RBAC, and white-label capability.

The Approach

Next.js frontend with theming, NestJS backend, PostgreSQL with row-level security for tenant isolation. Stripe for subscriptions. White-label via Caddy reverse proxy with automatic SSL.

Technical Decisions

Row-level security for database-level tenant isolation. NestJS modules mapped 1:1 to business domains. CSS custom properties for the white-label theming engine.

The Result

12 paying customers in month one. Zero data leakage across 200+ orgs. Automatic billing lifecycle. Three enterprise white-label contracts in month two.
