Fixed-price MVP development for funded founders. One senior developer owns your V1 from scope to launch, so you don’t need to hire a team, juggle freelancers or pay agency overhead.

Sound familiar?
You have the money and the idea. Not the technical co-founder.
You need someone senior to turn the plan into a real product, without spending months hiring a team or burning runway on the wrong build.
The demo works, but still feels unfinished.
You have something to show, but rough edges and unreliable flows make you hesitant to put paying customers through it.
Every feature creates another problem.
The backlog keeps growing. Fixes and new requests pile up, while the product gets harder to maintain.
You're doing everything
Managing developers, bugs and feedback takes time away from investors, customers and growing the business.
The V1 Sprint · How it works
From validated idea to launch-ready MVP.
A focused MVP build sprint for funded founders who need to turn a validated idea into a launch-ready V1, without hiring an internal development team.
V1 Blueprint
A paid 1–2 week scoping stage (£1,500, credited against the build). I map user journeys and agree the features, architecture and exclusions with you, then give you a fixed quote.
Design
Key screens and flows designed or refined, so you can see how the product will work and approve it before development. Suitable existing design can be reused.
Build and test
Built in focused sprints: onboarding, backend, screens and integrations. You review working builds at each milestone, and testing runs throughout.
Launch and handover
Submitted to the App Store and Google Play or deployed, with store reviews handled. You own the code and accounts; ongoing support is agreed separately.
Feedback is welcome throughout. Out-of-scope requests are discussed, estimated and approved before work starts, or added to a future phase.
What “launch-ready” means
Live in the App Store and Google Play, or on your own domain
Real users can sign up, onboard and use the core features
Payments or subscriptions working, where V1 needs them
Analytics and crash reporting in place from day one
Tested against the acceptance criteria we agreed up front
Code, accounts and documentation set up in your name
From £15k. Fixed scope. Costs tied to milestones.
It starts with a V1 Blueprint: £1,500 over 1–2 weeks for scope, key screens, a tech plan and a fixed quote. The fee is credited against the Sprint if you go ahead, so there are no open-ended invoices. Ongoing support after launch is agreed separately.
Your options
The usual routes to V1, and what they cost you.
Option 1
Hire an in-house team
Months of recruiting and a permanent salary bill before anything ships. The right move later, a heavy one for V1.
Option 2
Piece it together with freelancers
Lower day rates, but you manage the work, stitch the pieces together and own every gap between them.
Option 3
Hire an agency
A team behind an account manager, overhead priced in, your product in a queue and no real connection, with requirements often lost in translation

The right fit
Built for funded founders who are ready to build.
This is for you if…
You have raised £50k or more through SEIS/EIS, angels or pre-seed, or have budget committed to product. You are working on the business full-time, have validated the problem and can make decisions at agreed checkpoints. Established businesses launching a new app or internal tool without an in-house mobile team are a great fit too.
It’s not the right fit if…
You are building a side project with little time for feedback, working with a £3k–£5k budget, looking for a developer for a few days, or want unlimited changes without a clear decision-maker.
Questions, answered.
Can you work with our existing prototype or codebase?
Yes. I start by reviewing what you have, including products built in Lovable, no-code tools or with freelancers, then assess what can be kept, what needs improving and whether any part should be rebuilt. A rewrite is not the default.
How much does a V1 Sprint cost?
Every project starts with a V1 Blueprint: £1,500 over 1–2 weeks, credited against the build if you go ahead. Most V1 builds then sit between £15k and £30k+, depending on platforms, integrations and complexity. The Blueprint ends with a fixed proposal covering scope, milestones, cost and exclusions, so you know the total before development begins.
We’ve just raised. Can you plan the build around our investor milestones?
Yes. Discovery maps the V1 scope to what you need to show investors and early customers. The proposal sets out what will be live and when, so you can plan runway and investor updates with confidence.
Do you work with established businesses too?
Yes. If you run an established business launching a new app, customer product or internal tool without an in-house mobile team, the same sprint applies: one senior developer owning scope, build and release.
How involved do I need to be?
You provide the product context, priorities and timely feedback at agreed review points. I take responsibility for planning the technical work and delivering it. You stay involved in product decisions without managing the day-to-day development tasks.
What happens if the scope changes?
Feedback is welcome throughout the project. I estimate any requests outside the agreed scope before work starts, then we agree together on any effect on cost and timing, or move the request to a later phase.
Who owns the code and accounts?
You own the code. The repository, accounts and infrastructure are arranged in your name, with access and handover agreed as part of delivery.
What happens after release?
Ongoing support, maintenance and new features can be covered by a separate agreement. You and I agree the launch support and handover arrangements before the project starts.
Ready to turn your raise into a real product?
Tell me where your product is today. If we are a fit, you will leave the discovery call with a clear plan for your V1. Sprints start from £15k.
