We build the first working version of your SaaS. Real sign up, the core workflow your users came for, and the data, security and hosting behind it. Small enough to launch soon, and solid enough to keep building on.
What a SaaS MVP usually includes
Before development
Development goes best when a few things are clear. Tick what’s true for you today. Nothing you tick is saved or sent.

What an MVP is
An MVP is the smallest version of your product that real users can rely on for a real job. It’s small in scope, not in quality.
Deciding what to build
The hard part of an MVP is choosing what to leave out without leaving users stuck. Every feature on your list goes through four questions, and gets one of four answers.
If users can’t finish the main job without it, it’s in.
Features that test your riskiest assumption earn their place early.
Password resets, permissions and data protection aren’t optional extras.
Payments, email and some admin tasks often don’t need custom code yet.
What we build
Every SaaS MVP needs a few foundations. Beyond those, what we build depends on your workflow and your business model, so features are grouped by how often a first release really needs them.
Sign up, login, password reset and secure sessions.
The screens and logic for the one job your product does.
A data model built around that workflow, with validation and backups.
A production setup with secrets kept out of the code and errors logged.
Plans and checkout through an established payment provider.
Welcome emails, invites and alerts sent reliably.
A simple way for you to look up users and fix problems.
Events for sign up, setup and the core action, so you can see what users do.
When customers are companies with several users from day one.
When the product only makes sense connected to another tool.
When each customer’s data must be kept strictly apart from the start.
When AI is the core of the value, not a nice extra.
Technical approach
An MVP should be quick to build and cheap to run, but it still holds real customer data. These are the rules we follow to keep it simple without building something you’ll have to throw away.
A single, well organised application. Separate services add cost and moving parts an MVP rarely needs.
Established services for hosting, email, payments and login, instead of building them yourself.
Planned for version two, so new features don’t mean moving all your data.
Hashed passwords, permission checks on the server, safe input handling and backups.
Clear structure and documentation, so any developer can pick it up later.
Every deliberate shortcut is recorded with the point at which it should be revisited.
No MVP is built to scale forever. Some decisions will need revisiting as you grow, and that’s expected. Writing them down means the next step is planned rather than a surprise.
How it works
You work with one project lead from start to finish, and you get a written scope, timeline and price before any build work starts.
Your users, the problem, what success looks like and the assumptions behind it.
Your notes, research and any existing materialThe core journeys, the sorted feature list and what “done” means for each feature.
You approve the scopeThe architecture, data model, integrations and the order we’ll build in. Then a written timeline and price.
You approve the plan and priceWe build from your approved designs, or our design team creates them first.
You approve the screensThe core workflow first, then the rest, with a working demo at the end of each cycle.
You give feedback on each demoCore workflows, logins, permissions, payments and error states, on desktop and mobile.
You test it yourselfProduction setup, domain, backups, error logging and release to your first users.
You give the go aheadWe review what users did and agree the next set of changes with you.
You decide the next prioritiesTesting and launch
A small product still holds real people’s data and time. Before launch we check what users depend on and set up what you need to see problems early. No software is free of bugs, so we focus testing where a failure would hurt most.
After launch
Launching is where learning starts. An MVP gives you real evidence about what to build next. It can’t guarantee that the idea will succeed, but it tells you much sooner whether it’s working.
Your first users get access.
Tracked steps and errors show what people actually do.
Short conversations explain why.
Fix, improve or build next, based on evidence.
The next small release.
Scope and cost
We don’t sell fixed MVP packages, because one idea can need six screens and another sixty. You get a written scope, timeline and price before any build work starts.
Don’t have all of this? That’s fine. Working it out together is part of the first step.

FAQ
It’s building the first working version of a software product people use online. It includes real accounts, the core workflow, data storage and hosting, with enough functionality for your first users to rely on it and for you to learn from how they use it.
A prototype is clickable screens with nothing working behind them. It’s great for testing an idea and a flow. An MVP is working software with real accounts and data. If you need a prototype first, our SaaS MVP design service creates one.
It’s ready when you can name your first users, describe the problem in their words, say what the product must do, and know what you want to learn. If some of that is unclear, a short planning step or MVP design usually comes first.
Yes. We review them for missing screens, states and edge cases, then build from them. If anything is missing, we’ll flag it before development starts.
Yes. We look at what works, what users rely on and what’s holding you back, then plan a rebuild that moves your users and data across.
Each feature is checked against four questions. Is it needed for the core workflow? Will it teach us something? Is it required for trust, security or the law? Can a provider or a manual step cover it for now? Then it’s built now, handled by a provider or by hand, or saved for later.
We often use React and Next.js for interfaces, TypeScript, Node.js or Python on the server, PostgreSQL for data, and Docker and AWS for hosting. We choose what fits your product, and we prefer established tools over new ones for an MVP.
Usually not from scratch. We keep the code organised and the data model ready for version two. Some shortcuts will need revisiting as you grow, so we write them down with the point at which to revisit them.
You do. The code, designs and project files belong to you, and we hand over access and documentation at launch.
It depends on the number of user types, the features in version one, integrations, security needs and whether designs exist. You get a written scope, timeline and price before any build work starts.
We fix launch issues within the agreed period. After that, we can keep building with you, from small releases to growing it into a full product with SaaS application development.
No. An MVP gives you real evidence much sooner and for less money than building everything. Whether the product succeeds depends on the market, the offer and what you learn and change.
Book a call and tell us about your idea, your first users and what you’ve built so far. We’ll talk through what version one needs, what can wait and how we’d build it.
