The problem

Most SaaS rebuilds itself three times before product-market fit.

Tenancy, auth, billing, compliance — the foundations that everyone underestimates.

Multi-tenancy bolted on after the fact
Billing logic tangled into product code
Audit and RBAC retrofitted under enterprise pressure
No clear path from PLG to enterprise
Our approach

Foundations that absorb growth.

A reference SaaS architecture: clean tenancy, modular billing, fine-grained RBAC, complete audit trails — from sprint one.
Clean multi-tenancy

Row-level, schema-level, or DB-level — chosen for your scale.

Modular billing

Stripe + custom logic, decoupled from product code.

Fine-grained RBAC

Casbin-style policies, audit-logged.

Enterprise-ready

SSO, SCIM, audit exports, SOC 2 controls.
