From Business Problem to SaaS Product

SaaS begins when multiple organizations need the same workflow with different data—not when you buy Kubernetes.

Validate the workflow

Sell services or a single-tenant pilot until the steps repeat across clients.

Tenant model

Decide early: shared database with tenant_id vs schema-per-tenant. Optimize for your compliance story, not blog posts.

Billing later, isolation now

You can defer Stripe—but not authentication boundaries and backup isolation.

Roadmap discipline

One core loop in production beats five half-built modules.
