Web Apps & SaaS
Web Apps and SaaS Built to Grow
The Must-have features from your brief, built as a web app with sign-up, payments and an admin view, on widely used technology chosen so it can grow with you and so the next developer can pick it up.
What you get at each stage
Sized to where your product is now, and built so the next stage adds to it rather than starting again.
Idea & validation
Test demand before you build the product
- A landing page with a clear offer and sign-up form
- A waitlist, pre-order or demo booking flow
- Simple analytics to see where visitors come from
- The build approach in your brief checked against what the product needs
MVP & launch
Build the smallest product customers will pay for
- A web app with the Must-have features and an admin view
- Sign-up, login and payments
- Hosting, backups and monitoring set up from the start
- Fast, accessible pages that work well on mobile
Growth & scale
Keep the product fast and reliable as usage grows
- Performance work against Core Web Vitals
- Database and infrastructure scaling
- Automated testing and deployment
- Integrations, APIs and team features customers ask for
What is included

Accounts, login and card or subscription payments through a provider such as Stripe.
Performance

Scope it free, then build it
Your MVP brief is the brief
The brief you write in the free MVP builder is what we quote from. It tells us who the product is for, the Must-have features, the main journeys and the budget, so work on Web Apps & SaaS starts from your brief, not a blank page. It fits these stages:
In your brief
The sections it builds on
- MVP scope
- User journeys and screens
- Build approach
For established companies
New products and ventures, scoped first
Established companies use the same approach to launch a new digital product, a customer portal or a pilot service in a new market: a focused first version built and measured on its own, connected to existing systems only where it needs to be.
Tell us about your projectQuestions founders ask
What should a SaaS MVP include?
The one job customers will pay for, done well, plus sign-up, payments and the basic admin you need to run it. Team accounts, integrations and detailed reporting can usually wait until paying customers ask for them. The Must-have list in your brief is where this gets decided.
Which technology will you use?
We choose based on what the product needs and who will maintain it. For most web MVPs that means a widely used JavaScript framework such as React, with managed hosting and a managed database, so the next developer can pick it up. You own the code and the accounts.
How is a web app priced?
For a fixed price, agreed after a free scoping call and based on the Must-have features in your brief. If you add or change features later, we price the change in writing before work on it starts.
What rules apply to taking sign-ups and payments?
Collecting personal data means following UK GDPR: a privacy notice, a lawful basis and proper security. Cookies that are not strictly necessary come with their own consent rules. Card payments go through a provider that handles PCI DSS compliance, so card details do not pass through your own servers. We build these in, but have your terms and privacy notice checked by a legal adviser.
Who does the development work?
Our own team. We scope the work with you from your brief and build it ourselves: one brief, one point of contact and no hand-offs between agencies.
