MVP development for founders who need it built, not pitched.
Subscription platforms, member sites, and full SaaS products. Auth, payments, dashboards, and admin panels built with the modern stack you find behind Linear or Stripe. One developer who has shipped a subscription product to two app stores, working to milestones you agreed in writing.
The unglamorous parts, done right.
Accounts and access
Sign-up, sign-in, password reset, email verification, roles and permissions. The layer every product needs and nobody wants to pay to rebuild six months later because the first version could not tell an admin from a customer.
Payments and subscriptions
Stripe integrated properly: plans, trials, upgrades, cancellations, failed payment recovery, and webhooks that keep your database honest when someone cancels at two in the morning. Not a payment link bolted to a landing page.
Dashboards people can read
The screens your customers log in to use, designed to a SaaS-level visual standard rather than assembled from a bootstrap admin template. Clear states for empty, loading, and error, because real products spend time in all three.
Admin you can run the business from
Tools to find a customer, fix an order, refund a payment, and see what happened last week without asking a developer. The difference between a product you own and a product you depend on someone else to operate.
Typical stack:
Ship the first version, then decide.
The most expensive way to build a product is to specify everything upfront and discover after launch that customers wanted a different thing. An MVP is not a cheap version of the real product. It is the smallest build that puts a working, chargeable product in front of real users so the next decision is informed by evidence rather than opinion.
That means being deliberate about what is not in version one. Most feature lists have two or three things that genuinely prove the idea and a long tail that can wait until someone asks for them. Sorting the list honestly is part of the scoping work, and it is usually where the budget is saved.
Delivery runs on milestones rather than one long silence. Each milestone is a defined chunk of the product with a written scope and its own payment, and each one ends with something you can log into and use. If priorities change after milestone two, we change what milestone three contains instead of renegotiating the whole project.
You own everything as it is built — the code, the repository, the hosting accounts, the Stripe account, the domain. There is no proprietary platform underneath and no reason you could not hand the project to another developer tomorrow.
Founders who need a builder, not a team.
First-time founders
You have the domain knowledge and the customers but not the technical co-founder. The build needs someone who will push back on scope rather than quietly agree to everything and hand over a bill.
Existing businesses productising
You already sell a service and want to turn part of it into software customers pay for monthly. The hard part is deciding what belongs in version one, and that is where the scoping work earns its money.
Products that stalled
Something was started, the developer moved on, and it is 70% finished with nobody willing to touch it. I will read the code and tell you honestly whether finishing it or restarting is the cheaper route.
From £3,500. Milestone by milestone.
MVP SaaS builds start at £3,500 and most land between £3,500 and £8,000 depending on how much product is in scope. Larger builds split into milestones with written scope before each one begins, so you are never committing the full budget on the strength of a first conversation. Typical timeline is 6 to 12 weeks.
MVP questions
How long does an MVP take?
Typically 6 to 12 weeks depending on scope. The first milestone usually lands within 2 to 3 weeks so you are looking at something real early rather than waiting for the whole build.
Do you build mobile apps as well?
Yes. Instrumental Teachers Hub ships on iOS and Google Play alongside its web platform, built in Flutter with token-bridge authentication between the two. App store submission and review are handled as part of delivery.
What happens after launch?
Optional monthly retainer for updates, maintenance, and new features. Not mandatory — you own everything and can take it elsewhere if needed.
How do payments work?
50% deposit to start, 50% on delivery. Larger projects split into milestones. Bank transfer or Stripe invoice — your choice.
