MVP checklist for a few-week runway

Q: What truly belongs in a 4–8 week MVP?

One user role, one core flow (the action that proves the value hypothesis), basic auth (email + password or magic link), one payment path if monetisation is part of the test, and a minimum admin to read data. Everything else — analytics dashboards, advanced permissions, multi-currency, mobile apps, second integration — is post-MVP. If you cannot demo the core value in 10 minutes, the scope is still too wide.

Q: What does minimum viable infrastructure look like?

One Vercel/Render/Railway deployment, one managed Postgres (Neon, Supabase, RDS), one CDN-hosted asset bucket (R2, S3), one auth provider (Clerk, Auth0, Supabase Auth), one error tracker (Sentry), one analytics tool (Plausible or PostHog), one transactional email provider (Resend, Postmark). Total cost: $50–$200/month. Avoid Kubernetes, microservices, custom CI/CD pipelines and self-hosted databases at this stage.

Q: What observability do I really need for an MVP?

Three things: structured logs (Logtail, Better Stack or Vercel logs), error tracking with source maps (Sentry), and a product analytics tool that tracks the north-star metric (PostHog, Plausible, Mixpanel). Skip APM, distributed tracing and custom Grafana dashboards until you have paying users. The MVP question is 'are users completing the core flow?' — not 'what is p99 latency on the auth endpoint?'.

Q: What are the typical risks that kill a 4–8 week MVP?

Five recurring killers: (1) scope creep — adding features mid-sprint based on stakeholder opinions; (2) no named pilot approver — decisions take a week instead of a day; (3) building features without a real user to test them; (4) over-engineering infra (Kubernetes, microservices) before product-market fit; (5) treating the MVP as a finished product instead of an experiment — leading to obsessing over polish instead of learning.

One north-star metric (bookings, qualified leads or hours saved)—not ten.
Written out-of-scope for “nice” integrations that can wait until phase two.
Named pilot approver for each milestone and decision SLA.
Deployed demo environment separate from production for investors or internal committees.
Visible tech debt (temporary credentials, mock data) agreed upfront, not hidden.

If the MVP cannot be shown in a 10-minute demo, scope is still too wide—trim before week three of coding.

1. Diagnosing why most MVPs slip past 12 weeks

Every "4-week MVP" we have audited that ended up taking 12 weeks shared the same root cause: there was no written agreement on what the MVP was not. The team optimised for stakeholder consensus instead of learning velocity, every meeting added "just one more thing", and by week six the product had grown a settings page, a notifications system and three integrations — none of which moved the north-star metric.

A successful MVP is an experiment, not a product. Its purpose is to test the riskiest assumption (will customers pay? will users return? does the workflow save the time it claims?) with the smallest possible artefact. That requires brutal scope discipline upfront, a named decision-maker who can say no, and an infrastructure profile that costs $50–$200/month — not a Kubernetes cluster you will throw away in three months.

2. What to include — and what to cut

Keep in scope

One user role. Admin/member/viewer matrix can wait. Build for the role that proves the value.
One core flow. The 3–5 screens that take a user from sign-up to the "aha" moment that validates the hypothesis.
Basic auth. Email + password or magic link via Clerk / Auth0 / Supabase. No SAML, no SSO, no 2FA yet (unless the vertical demands it).
One payment path. Stripe Checkout with a single recurring price if monetisation is the test. No multi-currency, no proration, no annual+monthly toggle.
One integration. The one that unblocks the core flow (e.g. an OpenAI call, a Stripe payment, a Twilio SMS). Save the other five for phase two.
A minimal admin. A read-only page or simple CRUD over the main entities so the team can debug without SSHing into the DB.
Transactional email. Resend or Postmark with one welcome email and one password-reset email. No marketing automation, no Mailchimp.
One analytics event per step. PostHog or Plausible tracking sign-up, activation, and the core conversion event. The dashboard is your scoreboard.

Cut without negotiation

Multi-role permissions, multi-tenancy beyond a single org, internationalisation beyond one language.
Native mobile apps (use responsive web first — install a PWA prompt if you really need an icon on the home screen).
Custom design system (Tailwind UI, shadcn/ui, daisyUI or a template will get you to launch in a fraction of the time).
Advanced analytics dashboards, BI tools, custom funnels.
Automated email sequences beyond transactional.
Full Stripe Billing (proration, plan changes, coupons) if a single price suffices for the test.
Kubernetes, microservices, custom CI/CD, self-hosted databases.

3. Minimum viable infrastructure

Hosting: Vercel / Render / Railway / Fly.io. Pick one, never mix.
Database: managed PostgreSQL (Neon, Supabase, RDS). One DB, no read replicas yet.
File storage: Cloudflare R2 or AWS S3 — never the app server's disk.
Auth: Clerk (fastest), Auth0 (enterprise) or Supabase Auth (integrated).
Payments: Stripe Checkout. One product, one recurring price. Webhook handler with idempotency.
Email: Resend or Postmark for transactional. SendGrid only if you already use it.
Error tracking: Sentry with source maps. Configure release tagging on every deploy.
Analytics: PostHog (events + product analytics) or Plausible (lightweight, GDPR-friendly).
Logs: Vercel logs / Logtail / Better Stack — structured JSON with correlation IDs.
Total monthly cost: $50–$200 for the first 1,000 users. Anything more, you are over-engineering.

4. Week-by-week timeline (4–6 weeks)

Week	Deliverable	Risk if missed
Week 0	Brief + scope doc + named pilot approver + wireframes	Scope creep across the project
Week 1	Auth, database schema, deployed staging URL with placeholder UI	Infra rework in week 4
Week 2	Core flow happy path end-to-end, even if ugly	Late discovery of architectural mismatch
Week 3	Edge cases, basic admin, Stripe integration, transactional email	Payments and email tend to surface 80% of bugs
Week 4	Polish, analytics events, internal demo, 3–5 friendly users testing	No real users → MVP is a wish, not an experiment
Week 5 (optional)	Production launch, monitoring, support channel	If skipped, plan a 2-week buffer for bugs
Week 6+	Read analytics, talk to users, decide what to keep / cut / build next	Without this step, "MVP" was just a small product

5. Post-MVP success metrics

Activation rate: % of sign-ups completing the core flow within 7 days. Healthy: 25–50% for B2B SaaS, 5–15% for consumer.
Time to first value: minutes from sign-up to the "aha" moment. Under 5 minutes is the bar.
Retention at day 7 / 28: % of activated users still active. Healthy: D7 > 40%, D28 > 20% for SaaS.
Paying conversion: % of activated users converting to paid. Healthy: 3–10% for self-serve B2B SaaS.
Cost per active user: total infra + API costs ÷ activated users. Should be a tiny fraction of MRR per user.
Top 3 user-reported issues: not "all the bugs", just the three that block the most users. These define phase two.

6. Frequently asked questions

What truly belongs in a 4–8 week MVP?

One user role, one core flow, basic auth, one payment path if monetisation is part of the test, and a minimum admin to read data. Everything else is post-MVP. If you cannot demo the core value in 10 minutes, the scope is still too wide.

What should I deliberately cut from the MVP?

Cut: multi-role permissions, multi-tenancy beyond a single org, internationalisation beyond one language, mobile native apps, custom design system, advanced analytics, automated emails beyond transactional, full Stripe Billing if a single recurring price suffices. Cut these now and add them post-launch based on real user signals.
