SaaS MVP in 5 Weeks
Five weeks is enough time to build a real SaaS MVP when the scope is honest: auth, billing, the core workflow, an admin view, and a production deploy. It is not enough time for everything, and this page is direct about what fits, what does not, and what a fixed-scope build with senior engineers looks like week by week.
THE FIVE WEEKS
- WEEK 1
Scope, architecture, data model
The wedge defined in writing: the one workflow the MVP must do well. Architecture decided, data model sketched, repo and CI stood up.
- WEEK 2
Core build, first pass
The core workflow stood up end to end, rough but real, and demoed to you at the end of the week.
- WEEK 3
Core build, complete
The workflow finished with its real states: empty, loading, error, success. Second demo, scope check against week one.
- WEEK 4
Auth, billing, integrations
Accounts, roles and permissions, Stripe billing plumbing, and the integrations that are load-bearing for launch.
- WEEK 5
Hardening, deploy, handover
Error paths, tests on the money paths, production deploy, a runbook, and a handover call with your team.
DELIBERATELY CUT
Five weeks is a budget, and budgets force choices. These are the cuts, made on purpose and written into the scope so nobody discovers them at handover.
Admin polish
You get a working admin, not a beautiful one. Your team can operate it from day one; the styling waits for phase two.
Edge-case states
The core path is solid. Rare paths fail safe and route to a human instead of pretending to handle everything.
Scale work you do not need yet
You need your first fifty customers, not fifty thousand. We build for the load you have plus headroom, and we write down where the ceiling is.
The marketing site
The product is the wedge. Landing pages and content are a separate, smaller scope, usually after the MVP is live.
WHO THIS IS FOR
- A founder with a scoped wedge: one workflow, one user type, one promise
- You can name your first ten users and what they are paying for
- One decision-maker available for a weekly demo and fast answers
- You would rather learn from a live product than from another month of planning
WHO IT IS NOT FOR
- A platform dream: three user types, two marketplaces, and an admin empire in v1
- Committee decisions: every added reviewer costs a week, and five weeks has none to spare
- Products where wrong answers carry regulatory or safety exposure without a compliance phase
- Anyone who needs everything in the first release
PROOF
- SaaS Backend / MVPThe package this page describes: production backend, auth, billing, admin, deployment, fixed scope. Five weeks is the tightest honest version; bigger wedges run longer and are scoped on the call.

FAQ
What founders ask before committing the five weeks.
- What happens after week 5?
- You own a live product, the repository, and a runbook. Most teams continue with a Monthly Engineering Retainer or a scoped phase 2; some take the code in-house. All three are planned exits, not lock-in.
- Can five weeks really produce something production-ready?
- Yes, when the scope is a wedge: one core workflow done properly. No, when the scope is a platform. The scoping call exists to tell you which one you have.
- What do we need ready before week 1?
- A decision-maker, the core workflow described end to end, and access to the accounts and APIs the product depends on. Missing any of these moves the start date, not the quality bar.
- What if our scope does not fit five weeks?
- We tell you on the call and cut scope with you until it does, or we propose a phased build. The calendar never stretches silently.
- Who owns the code?
- You do, from day one. The repo lives in your GitHub org from kickoff, every commit visible.
- Does this include a mobile app?
- No. Mobile is a different timeline and team shape, and it is scoped separately.
