MVP development for UK founders and corporate teams
An MVP is not a cheap version of the full product. It is the smallest complete loop that answers one question: will people use this, and will they pay? Everything else waits.
Outcomes
- Working product in front of users in 8 to 14 weeks
- Evidence for the next funding or budget conversation
- A codebase that scales rather than one thrown away
- A prioritised roadmap based on usage, not opinion
Service
Where it is used
Founder validation
Prove the core loop before raising or committing a large budget.
Corporate innovation
Test a new revenue line without disturbing the core systems.
Pre-sales prototype
Something real to demo to your first ten prospects.
What we deliver
- Scope reduction workshops
- Rapid design and clickable prototype
- Production-grade build of the core loop
- Analytics and feedback instrumentation
- Launch support and iteration sprints
Who this is for
- Founders who need something real in front of paying users before raising or committing further
- Corporate teams testing a new revenue line without disturbing the core platform
- Anyone who can name the single assumption that decides whether the product is worth continuing
When this is the wrong choice
- Products that must launch fully regulated and feature-complete on day one
- Teams who mean 'the whole platform, cheaper' when they say MVP
Problems this solves
Spending a year before learning anything
The costly mistake is not building the wrong feature; it is building twelve of them before the first user opens the product.
Prototypes that cannot grow
A throwaway demo wins the pitch and then has to be rebuilt. We build the smallest honest version of the real thing.
No usage evidence for investors
Retention and activation numbers from real users change a funding conversation more than any deck.
Architecture and integration
- Boring, well-supported technology — an MVP is not the place for a stack experiment.
- Managed authentication, payments and email rather than custom infrastructure at this stage.
- Analytics on the core funnel from day one; without it, launch teaches you nothing.
- A data model that can take the next two features without a migration nightmare.
How delivery runs
- 01
Assumption workshop
We name the riskiest belief and design the release that tests it. Everything not serving that test is deferred in writing.
- 02
Cut list
An explicit list of what is out of scope for v1, agreed by everyone, so it stops being reargued weekly.
- 03
Eight to fourteen week build
One usable journey end to end, instrumented so you can see where people drop.
- 04
Launch and read the data
Two to four weeks of real usage, then a prioritised plan based on behaviour instead of opinion.
Realistic timeline
Weeks 1–2
Assumption, scope, cut list, flows.
Weeks 3–10
Build of the single core journey.
Weeks 10–14
Beta with real users, instrumentation, launch.
What moves the price
How many user types
One user type is an MVP. Three sides of a marketplace is a platform, priced accordingly.
Payments and compliance
Taking money adds flows, edge cases and refund handling.
Design ambition
A clean system-based interface is quick; bespoke illustration and motion work is a separate line item.
Where projects go wrong
Scope creep disguised as polish
Every added 'small' feature delays the only thing that matters — contact with real users.
No distribution plan
An MVP with no route to users tests nothing. We ask about the first fifty users in week one.
Treating v1 as final architecture
Some of it should be rewritten after launch. Pretending otherwise leads to over-engineering.
What is different in this market
UK funding context
UK pre-seed and seed conversations increasingly expect usage evidence, not just a deck. We instrument activation and retention from launch so those numbers exist.
What UK pricing looks like
Quoted in GBP against a fixed scope rather than an open day rate. Comparable UK agency day rates sit well above offshore rates; we price the delivered scope so the comparison is like for like.
Indicative budget
Scope discipline, not day rate, is what keeps an MVP in this band.
FAQ
Questions buyers ask
Will we have to rebuild it later?+
No. We cut scope, not engineering quality — the MVP is the first version of the real system.
What if the market says no?+
Then you learned it for a fraction of the full build, which is exactly what the MVP was for.
You already have the idea. Let's define what comes next.
