Overview
What this service is
We've shipped enough SaaS systems to know which decisions you'll regret. We help you skip them.
What's included
Multi-tenant data model
Org-scoped, row-level, audit-ready.
Stripe billing integration
Subscriptions, metered usage, invoices, dunning.
Admin + customer portal
Two distinct surfaces, one shared design system.
Feature flags + experiments
Ship safely, measure what matters.
SOC 2-ready scaffolding
Audit logs, access reviews, encryption at rest.
How it runs
Four phases. Production from day one.
Model
Tenants, roles, plans, limits — written down before code.
Build
Vertical slices, end to end, with billing wired early.
Operate
Internal tools so support and ops aren't blocked on engineering.
Scale
Backpressure, caching, queues — added when needed, not before.
