Groundwork

Shipped. In weeks.

Zero to live in weeks. Auth, billing, multi-tenancy, and onboarding flows shipped as a complete product foundation — so you build the thing that matters, not the plumbing.

Multi-tenancy Stripe Billing Auth & Onboarding Admin Dashboards

The same foundation every SaaS needs. Built once, properly, so you never rewrite it at scale.

Multi-tenancy
Row-level tenant isolation using acts_as_tenant. Every query scoped automatically. Org switching, per-tenant settings, and subdomain routing — without the footguns of rolling it yourself.
acts_as_tenant Row-level isolation Org switching
Stripe Billing
Subscriptions, metered usage, per-seat pricing — whatever your model needs. Upgrade and downgrade flows, trial periods, dunning emails, and the webhook handlers that actually cover the edge cases.
Subscriptions Usage-based billing Dunning flows
Auth & Onboarding
Email/password and social login via Devise or Rodauth. Invitation system, email verification, password reset, and a step-by-step onboarding checklist that gets users to value before they churn.
Devise / Rodauth Social login Invitation system
Admin Dashboard
A super-admin panel for your team — impersonate any user, inspect any account, manage subscriptions without touching the database. Built for support and ops from day one.
User impersonation Subscription management Ops tooling
Feature Flags
Gate features behind plans, per-tenant overrides, or rollout percentages. Works with Flipper or a simple DB-backed implementation. Add a beta feature for one org without shipping to everyone.
Plan gating Flipper / custom Per-tenant flags
Transactional Email
Welcome, email verification, trial ending, payment failed, invitation — every email your product needs, templated, tested, and wired to the right lifecycle hooks from the start.
Lifecycle emails Trial & dunning Postmark / Resend

Proven Rails patterns, not homebrew frameworks you'll regret at 10,000 users.

Foundation

We spend the first week wiring auth, billing, tenancy, and transactional email together properly. Every piece connected to every other piece. No gaps you discover at 2am.

Your product logic
Build

Your domain logic sits on top of the foundation — clean separation so billing and auth never leak into your actual product code. We build the feature you're here to ship.

Kamal deploy, SSL, custom domain, Stripe webhooks configured in production. The whole stack live and taking real signups in week two, not week eight.

Once users are in, we iterate on the onboarding funnel. Trial to paid conversion is the metric we watch. Feature flags let us test gate changes without redeploying.

Stop rebuilding auth again.

Tell us what your SaaS does. We'll scope the foundation and ship your first paying signup in weeks, not quarters.
