SaaS Development
Multi-tenant, billed, deployable. Not a prototype.
We build production SaaS products for founders — multi-tenant from day one, Stripe-ready, with the admin tooling you'll actually need at 100 customers. One senior engineer owns the architecture; you don't pay for a three-person team to argue about microservices.
What you get
Concrete deliverables.
Not a slide deck.
- Multi-tenant data model with row-level isolation from commit one
- Stripe subscription billing with usage-metered or seat-based pricing
- Customer admin (workspace settings, members, billing) and internal admin
- Onboarding flow with email verification, password reset, SSO-ready
- Source + infrastructure handed to your accounts
Why us
The shape of the work matters.
- Senior engineer who has shipped paid multi-tenant SaaS — the failure modes are known, not learned on your build
- Stripe, billing, and tenancy are wired correctly the first time (RLS, webhooks, dunning)
- Architecture chosen for your traffic profile — not the cargo-cult stack of the month
- Flat price including the 'second sprint' work most agencies sell as a change order

FAQ
Questions founders ask.
How fast can you start?
Most builds begin within seven days of the first call. We don't sell discovery — we go from problem statement to first deploy on the same day-one timeline.
Is the price really flat?
Yes. After a 30-minute call we send a single number and a scope you can accept or reject. No hourly billing, no change-order games. If we underestimate, we eat it.
Do you handle Stripe end-to-end?
Yes — checkout, customer portal, webhooks, dunning, upgrade/downgrade prorating, trial logic. We assume you want it billed-ready, not a 'connect Stripe later' placeholder.
Can you do enterprise features (SSO, audit log)?
Yes — SSO via WorkOS or Clerk, audit logs, role-based access. Most are quick adds because the multi-tenant base is already correct.
Who owns the code?
You do, from commit one. The repository is created in your GitHub org. Infrastructure is provisioned in your cloud account. We don't host your stack on ours and we don't lock you in.
