From idea to MVP in 14 days with an AI-native dev workflow
6 May 2026 · 6 min read · TheAIgency
TL;DR. 14 days from kickoff to a single-tenant production MVP with auth, one core workflow, a simple admin, and Cockpit-assisted dev throughout. The trick isn't moving faster — it's brutally cutting scope and using AI for the boring parts (boilerplate, types, tests) so the human time stays on the parts that matter (data model, UX, edge cases).
The 14-day playbook
- Day 1 — single-page spec. One page describing the user, the core loop, and what "v1 success" looks like. If it doesn't fit on one page, we cut.
- Day 2 — data model + schema. Drizzle schema, migrations, seed data. We design for the v1 — not for the v3 we might want.
- Day 3 — auth + user shell. Whatever auth provider the client wants (we default to Auth.js). Empty dashboard, navigation, basic theming.
- Day 4-7 — the core loop. The actual feature. This is the only part where we slow down. Every other day is supposed to be fast.
- Day 8 — admin shell. Bare-bones admin: list users, view records, basic actions. No analytics yet.
- Day 9 — first deploy + smoke test. Vercel preview, run through the loop end-to-end with the client.
- Day 10-11 — fix what surfaced. Always something. Edge cases, UX papercuts, data model mistakes.
- Day 12 — onboarding flow + emails. Resend for transactional emails. Welcome flow.
- Day 13 — polish + content. Copy passes, empty states, loading states, error states. Cockpit Copywriter agent drafts copy; human edits.
- Day 14 — production deploy + handoff. Custom domain, monitoring, codebase walkthrough.
What we skip on purpose
| Thing | Why we skip it on day 1-14 |
|---|---|
| Multi-tenancy | That's V1's job (8-12 weeks). Single-tenant first. |
| Stripe billing | Same. Add it once you have validated demand. |
| Full admin analytics | Day 8 builds a list view. Charts can wait. |
| i18n | Single language for MVP. We add EN/FR in V1. |
| SSO / OAuth providers | Email + password is enough at MVP scale. |
| Mobile app | PWA is fine. RN starts at Scale-up. |
| Long-form marketing site | Ship a landing page (Spark tier) separately if you need it. |
What we can't skip
- Real auth. Don't fake it. The MVP that goes to production needs real users with real accounts.
- Honest data model. If you cut corners here, V1 becomes a rewrite instead of an extension.
- Empty states. First-time users will see them; they're more important than your hero.
- One end-to-end test of the core loop. Can be Playwright or even a manual checklist; just commit it.
Where Cockpit speeds us up
Boilerplate generation (forms, tables, CRUD endpoints), type inference from schema, test scaffolding, copy drafts, and code review on every PR. Cockpit doesn't replace the developer — it removes the boring 30% so the human time lands on UX, data model, and edge cases.
When MVP is the wrong tier
If you already have validated demand, paying customers waiting, or the core loop requires multi-tenancy from day one — skip MVP and go to V1. We've watched founders waste a month on an MVP that needed Stripe billing on launch day; just start at V1.
