Fixed-scope packages
For founders, startups, SMEs, and innovation teams that need a visible result.
- Idea Validation Sprint
- Rapid MVP Sprint
- AI Integration Sprint
- Interactive Prototype Sprint
Some clients need a fixed outcome. Some need senior engineering capacity. Some need a long-term technical partner. The working model should match the risk you are trying to remove.

The goal is not to force everything into one service shape. It is to choose the commercial structure that helps you move fastest with the least confusion.
For founders, startups, SMEs, and innovation teams that need a visible result.
For agencies and companies that already know what they need and want extra senior delivery capacity.
For companies building products over several months that need continuity and strategic technical direction.
The three models are not tiers of the same thing. They buy different kinds of certainty, and they suit different moments.
An Idea Validation Sprint at £495 is a 90-minute workshop, a feasibility review, an architecture outline, a roadmap and a budget estimate. A Rapid MVP Sprint from £2,995 is a two-week build path covering authentication, dashboard, backend, deployment and a demo-ready proof. An AI Integration Sprint at £1,995 delivers one working AI feature, chatbot or automation, deployed and documented.
Use this when the thing you lack is confidence, not capacity.
View the packagesDay or weekly engineering support, embedded in your team, across Unity, WebGL, full-stack, AI and dashboards. No discovery phase, no re-litigating the brief — you already know what needs building and you need someone senior enough to build it without supervision.
This is the model most agencies and studios use, usually when they have won work with a technical component they do not staff internally.
Ask about capacityFrom £1,500 a month for ongoing technical direction: architecture and roadmap, prototype reviews, implementation support, and launch and iteration work. The value is that nobody has to be re-briefed every time the product moves.
Worth it when the product will keep changing for months and the cost of losing context between engagements is higher than the retainer.
View retainersFour situations that come up constantly, and the honest answer to each.
Start with a prototype or proof of concept, from £2,800. The job is to make the idea visible enough for someone to say yes to it — one journey, working, against realistic content. Everything else can wait until the budget exists.
A Branded MVP from £9,000. Core features, a polished interface, basic integrations, and enough finish that you would be comfortable putting it in front of a customer rather than a colleague.
A production build from £28,000. Architecture, integrations, QA, deployment, launch support and a codebase somebody else can maintain. The jump in price over an MVP is almost entirely the parts you cannot see.
Then buy the £495 validation sprint before anything else. It is the cheapest way to find out that an idea is smaller, larger or different from what you assumed — and occasionally that it should not be built at all.
No lengthy discovery phase before anything useful happens. The aim is to get from first message to something you can look at in weeks, not quarters.
The most useful brief describes what is going wrong and who it affects. “Our engineers cannot see which assets need attention” is far more workable than “we need a digital twin”, because it leaves room for the answer to be simpler than you feared.
Usually 15 to 30 minutes. We are looking for the thing that decides everything else: a deadline, a stakeholder who has to be convinced, a system that may or may not have an API, or a budget that has a hard ceiling.
You get back what would be built, what would deliberately not be built, which band it falls in, and roughly how long. If the honest answer is that you should buy something off the shelf or configure a tool you already pay for, that is what you will be told.
Something is in front of you early enough to change your mind about. This is the whole point of working in small sprints — feedback in week two is worth more than a perfect specification in week one.
Every engagement ends with a decision rather than a handover of files: expand, adjust, pause, or stop. Work that ends with “stop, and here is why” has done its job as much as work that ends with a launch.
The technology matters, but the buying reason is usually speed, clarity, and confidence.
Automate repetitive work, reduce admin, speed up decisions, and make internal knowledge easier to use.
Help engineering and operations teams visualise assets, sites, workflows, and scenarios faster.
Build interactive products stakeholders can actually use, test, approve, and show to others.
The things people ask before they book a call.
By what is uncertain. If the idea itself is unproven, buy a fixed-scope sprint — the point is to reach a decision. If the brief is already clear and you just need hands, buy capacity. If the product will keep changing for months, buy a retainer so the thinking stays continuous.
The £495 Idea Validation Sprint. It is a 90-minute workshop plus a feasibility review, an architecture outline, a roadmap and a budget estimate. It is deliberately priced so that finding out an idea is not worth building is cheap rather than painful.
Yes. A good share of the work is delivery capacity for agencies and studios who have already won the brief and need senior engineering on Unity, WebGL, full-stack, AI or dashboards. That is a day or weekly rate rather than a fixed package, and white-label delivery is priced on request.
Because the same-sounding brief can differ tenfold in effort. Integrations, content volume, platform targets, design depth, deployment and how many stakeholders need to review it all move the number. The published figures are honest floors, not anchors to negotiate up from.
That is normal, and it is the reason the three models exist rather than one. Fixed-scope work is deliberately small enough that changing direction means starting a new sprint rather than renegotiating a contract. If change is expected from the outset, a retainer is the cheaper structure.
A validation sprint can usually be booked within days. Build work depends on current capacity, which is the honest constraint of a founder-led studio — we would rather tell you the real start date than take a deposit and queue you.
If the idea is early, validate it. If the risk is technical, prototype it. If the brief is clear, bring in engineering capacity. If the product keeps evolving, use a retainer.
