SaaS & MVP Development

From idea to paying customers in weeks, not quarters

I build and run my own SaaS products, so I know what it takes to get from a spec to people paying you. You get one senior developer who covers architecture, back end, front end, payments, hosting and launch.

Sound familiar?

  • You have a validated idea but no technical co-founder
  • An agency quoted six months and a six-figure budget
  • A previous build stalled, and you need someone to finish it and make it production-ready
  • You need the MVP to hold up once the first real customers arrive, not just a demo

What you get

  • Paid discovery workshop, then a written scope and cost estimate
  • Production web app: sign-up, accounts, payments (Stripe), admin and email
  • Cloud hosting, CI/CD, backups and monitoring set up in your own accounts
  • Full source code and ownership: no lock-in

Ways to work together

Every engagement starts with a small, paid, fixed-price first step. That's where requirements are gathered and the scope and cost estimate for the rest of the work are written, so you know what you're committing to.

Discovery & scope

from £1,500

Workshop, user flows, technical architecture and a cost estimate for the build.

MVP build

from £12,000

A launch-ready product with payments, auth, admin and hosting. Estimated during discovery.

Ongoing support

from £900 / month

Hosting, updates, fixes and new features on a monthly retainer.

Common questions

How much does it cost to build an MVP?

A paid discovery and scope starts from £1,500. A launch-ready MVP with payments, accounts, admin and hosting starts from £12,000, and the actual figure for your product is estimated during discovery, once the scope is written down. Ongoing support and new features start from £900 a month.

Why start with paid discovery?

Because a build estimated from a short conversation is a guess. Discovery turns the idea into user flows, a technical architecture and a written scope, so the cost of the build is based on what you actually need and you can decide with real numbers in front of you.

Who owns the code and the accounts?

You do. Hosting, payments, email and source control are set up in your own accounts, and you get the full source code. There's no lock-in, so you can bring the product in-house or move to another developer whenever you choose.

Have you built and run SaaS products yourself?

Yes. I design, build and run my own live products, including Lineplate, which turns 3D CAD assemblies into technical documentation in the browser, and My House Move Plan, StoryPrompt and AccessDrop. So I deal with sign-up, payments, hosting, support and the problems that only show up after launch myself.

Can you take over a build that has stalled?

Yes. That includes apps started by another developer or agency, and apps built with AI tools that work as a demo but aren't ready for real customers. The first step is a review of what's there, so you know what can be kept, what needs fixing and what it will cost before any further build work.
