MVP

SaaS MVP development

We build SaaS MVPs that can both ship to early customers and carry continued development for many months after. No prototype spaghetti, no heavy frameworks you'll never use.

How we think about MVPs

An MVP isn't a half-finished product.

An MVP isn't a half-finished product — it's the smallest product that solves a real problem for one clear customer type. We've built quite a few now, and we've learned that the best MVPs are focused, fast, and built on a stack that doesn't have to be thrown out when 200 customers show up. That's not the same as "quick and dirty" — it's quick and focused.

We work in 8–14 weeks from idea discovery to a running, paid-for SaaS in production. We build on Next.js (App Router), Postgres (Supabase or Neon), TypeScript, Tailwind and a handful of documented patterns we know hold up. We bring multi-tenancy, billing (Stripe), auth (with organisations and roles) and email (Resend) in from day one — because it's far more expensive to bolt those on later than to build them right from the start.

We understand that a startup MVP and an internal proof-of-concept are different beasts. A startup MVP needs to stand up to customers who don't know you, pay with a credit card, and are impatient. We build it with proper onboarding, a realistic feature roadmap and a plan for what happens when your first big customer asks about SOC 2 documentation.

The process

Four phases. Weekly demos. No surprises.

We work in short iterations with deploys from day one, so you can continuously see and use what we build. The end date is locked in discovery — scope is what we adjust if priorities shift along the way.

  1. Week 1–2

    Discovery & design

    We lock MVP scope, design the core flows in Figma, choose the stack and lay out a realistic plan with weekly demos. You walk away with a clear budget and a risk register — before we touch a codebase.

    • Scope document and roadmap
    • Wireframes and design-system foundation
    • Tech architecture and stack choice
    • Risk register and mitigation plan
  2. Week 3–6

    Foundation

    We build the foundation: auth, multi-tenant data isolation, billing and the internal tooling your team will use. Preview deploys on every pull request from day three — so you can click through continuously.

    • Auth.js or Clerk with organisations
    • Postgres with RLS and migrations
    • Stripe billing + Customer Portal
    • CI/CD pipeline + preview environments
  3. Week 7–10

    Features

    Now we build what your product is actually about. 2–4 main features built in close dialogue with you and — if possible — early pilot customers. Daily deploys to staging, weekly demo.

    • 2–4 main features fully working
    • Onboarding flow and user invitations
    • Transactional emails (Resend)
    • Mobile-responsive UI across the product
  4. Week 11–14

    Polish & launch

    Performance tuning, security review, documentation and go-live. The first customers are onboarded with us at hand, and we continue with operations and ongoing development by agreement.

    • Performance & security review
    • Operations monitoring and on-call
    • User and admin documentation
    • Soft launch with pilot customers

What's in the box

The default stack we build on

We choose differently when it makes sense — but rarely. This stack lets us move fast without building technical debt we'll have to pay back later.

  • Next.js

    Frontend, SSR and API routes

  • TypeScript

    End-to-end type safety

  • PostgreSQL

    Primary database (Supabase or Neon)

  • Tailwind CSS

    Design system and UI

  • Vercel

    Edge hosting and preview deploys

  • Cloudflare

    DNS, WAF and edge cache

  • Node.js

    Backend runtime and workers

  • Python

    ML and data pipelines where relevant

What we deliver

This is what we actually build.

Done in 8–14 weeks. Not a checklist — this is what a typical MVP delivery looks like in practice.

  • Discovery and scope

    1–2 weeks to lock MVP scope, design core flows, choose the stack and lay out a realistic plan with weekly demos. You get a clear budget and a risk register, not an estimation magic show.

  • Multi-tenant architecture

    Organisations, users, invitations, roles and data isolation from day one. Built on proven Postgres patterns (Row-Level Security or schema isolation) so it scales from 1 to 1000 tenants without redesign.

  • Auth and user management

    Email/password, magic links, Google and Microsoft SSO. Invite flow, password reset, MFA where it makes sense. Built on Auth.js, Clerk or WorkOS depending on where you're heading.

  • Billing with Stripe

    Subscriptions, trials, per-seat or per-usage, invoices and self-service via Stripe Customer Portal. Webhook handling with idempotency — so you never charge twice or lose a payment.

  • Transactional emails

    Welcome, invitations, invoices, alerts and notifications delivered reliably via Resend or Postmark. With templates that look like your product and open/click tracking where you want it.

  • Operations, monitoring and support

    Vercel or AWS hosting, Postgres with backups, Sentry for error reporting and a small on-call rotation where we take the page when something breaks outside business hours.

Scope

Three engagement levels. Pick the one that matches the ambition.

We always talk scope and price in discovery — never on a website. These are the ranges we typically work within so you can see where your MVP roughly lands before we meet.

  • Lean

    8–10 weeks

    Focused MVP to validate the idea with the first paying customers. Gets you to market fast.

    • Auth + multi-tenant from day 1
    • Stripe billing with trial
    • 1–2 main features
    • Vercel hosting + Sentry
    • GitHub setup + CI/CD
    • 4 weeks of stabilisation
  • Our recommendation

    Standard

    10–12 weeks

    Complete MVP for most startup cases. Our recommendation for the vast majority.

    • Everything in Lean
    • 3–4 main features
    • Advanced role management
    • Transactional emails
    • Onboarding flow with invitations
    • Admin dashboard
  • Complete

    12–14 weeks

    Larger scope with integrations, compliance and advanced architecture. For B2B and regulated industries.

    • Everything in Standard
    • 5–7 main features
    • 3+ external integrations
    • GDPR + SOC 2-ready architecture
    • Custom analytics & reporting
    • Pilot onboarding support

Each level covers discovery, build, ops setup and 4–6 weeks of stabilisation after go-live. Operations and ongoing development are agreed separately after go-live.

Before we start

What you should consider first.

  • Stack choice

    We default to Next.js + Postgres + TypeScript because that stack is fast to build in, fast to hire on and fast to operate. If you have a good reason for a different stack (existing team, integration with a .NET backend, particular performance requirements), we'll use it. But we choose the stack only after we've talked about what's being built — not the other way around.

  • Timeline and scope

    8–14 weeks is the normal range for an MVP that includes auth, multi-tenancy, billing and 2–4 main features. If scope is smaller (internal PoC), we can do it in 4–6 weeks. If scope is bigger (you have a 30-item feature list), we need to talk about what comes in v1 and what waits — because a 30-item MVP isn't an MVP.

  • Pricing and business model

    We're not your CFO, but we've seen many pricing models. We set Stripe up so you can experiment — monthly vs. annual, per-seat vs. per-usage, free trial vs. pilot — without code changes every time. It's more important to be able to change the pricing model after a month than to nail it from the start.

  • Who owns the code

    You own the code. It lives in your GitHub organisation from day one, your team gets access, and you can take it elsewhere if we're no longer the right partner. We believe good agreements aren't built on lock-in.

FAQ

What people usually ask.

  • What happens in discovery?

    In two short weeks we lock the MVP scope, design the core flows in Figma, choose the stack, and build a realistic plan with weekly demos. You leave with a clear scope, a risk register, and an open budget — before we touch a codebase. Price and scope are always discussed privately in the conversation, not on a website.

  • How quickly can we be live?

    8–14 weeks from first conversation to paying customers is normal for a focused MVP. We run weekly demos from week 2, have preview deploys on every pull request, and let you (or your first pilot customers) try the product continuously. "Live" isn't a magic date — it's a gradual rollout from internal testers to pilot customers to public launch.

  • Who owns the code?

    You do. The repository sits in your GitHub organisation from day one, your team can have commit access whenever you want, and the entire codebase is yours. We don't believe in lock-in. If at some point you want to take development in-house or use a different agency, that's your call — we'll do a proper handover and bow out gracefully.

  • What happens after the MVP is live?

    It depends on what you want. Many customers choose a monthly operations and development agreement where we handle new features, support, security updates and operations on a fixed price. Others take development in-house and have us only operate. Or a middle ground where we're backup when your team is stretched. We talk about it well before go-live — it shouldn't come as a surprise.

  • How do we know the MVP will be built right?

    We work with a stack and a set of patterns we've used across multiple SaaS builds and know hold up. We do weekly demos so you can see progress, we have preview deploys on every PR so you can test continuously, and we do code review internally so no code goes to production without being seen by two pairs of eyes. And when something does go wrong — because it will — we fix it and learn from it. That's the difference between a team that's built this kind of thing before and a team building it for the first time.
