Some engagements need more than leadership. They need a team that builds. End-to-End Product Development is our delivery service: we take your product from an idea, or from wherever a previous attempt stopped, to a launch that can take money and stand up to scrutiny. Specification, foundations, build, pre-launch review, launch and handover, with one partner accountable across the whole cycle.
A growing share of this work is project rescue. Products assembled quickly, whether vibe-coded with AI tools, built by freelancers or handed between teams, often demo well and then stall exactly where prototypes were never meant to go: payments, many simultaneous users, personal data and compliance. We diagnose what is salvageable, reconcile every earlier decision into one written plan, and rebuild on foundations that can carry the real business. Read how we rescued a failed project and shipped it in five weeks.
A build rarely stops at the code. When the business model needs to change with the product, we work on that too: pricing and plans, a second revenue channel, the go-to-market plan for launch. Research-backed ventures often hold genuinely valuable IP with no product organisation around it; we build the platform and the commercial shape that turns validated research into a business.
We deliver with modern AI-assisted tooling, which is why a senior team can ship in weeks what once took an agency months. The speed holds only because senior judgment decides what gets built, what gets tested hardest and what gets thrown away. Built for the next decade, delivered at this decade's pace.
A good fit when
- You have a product to build and want one partner accountable from specification to launch
- You have a prototype or an earlier build that demos well but cannot take money, scale, or pass scrutiny
- You have a fixed date, such as an investor milestone, a contract or a launch, and cannot afford drift
- You are a research-backed venture with validated IP and no product team around it
- You want a partner who will challenge the business model, not just build to the brief
Not the right fit when
- You want the cheapest possible build and will decide on price alone
- You need a team to follow instructions without questioning scope
- Nobody on your side can sign off on what "done" means
How a build runs
The phases are the same on every engagement. The detailed steps, timings and terms for yours are set out in the proposal.
-
Discover
Diagnose
A fixed-fee, honest read on what you have: what carries forward, what doesn't, and what it will take to launch. You can stop here with a clear answer.
-
Strategize & Plan
Specify
One written specification with acceptance criteria, reconciling every earlier document and decision. You sign off on what "done" means before we write code.
-
Implement
Build
Milestone-gated delivery on dependable foundations. You see working software at every milestone and pay on delivery, not on promises.
-
Optimize
Break it before your customers do
A deliberate review that treats the product the way a real customer, a real accountant and a real bad day will. Everything it finds is fixed and verified first.
-
Sustain & Grow
Hand over
Documentation, training and a defect-warranty period agreed in writing. Prices and business rules are settings you can change without calling us.
How an engagement works
- Timeline
- Weeks, not months. Our most recent rescue went from takeover to launch in five weeks, including a business-model expansion mid-build. Your timeline is set in the specification, not guessed.
- Commercials
- A fixed-fee diagnosis you can stop after. The build is priced against the signed specification and paid on delivered milestones, so you always know what you will get, when, and for how much.
- Warranty
- A defect-warranty period agreed in writing before the build starts. If something we shipped does not do what the specification says, we fix it.
- Who does the work
- One senior lead accountable to you from the first call to handover, backed by the specialists the work needs: product and business strategy, architecture and engineering, design, data and AI, quality, and go-to-market. Modern AI-assisted tooling makes the team fast; senior judgment decides what gets built and what gets tested hardest.
- Business model and go-to-market
- Pricing, plans, channels and the launch plan are worked through with you during the build, not after it. In our most recent rescue that meant adding B2B plans and a go-to-market plan mid-build, without moving the date.
- After launch
- Documentation, training and a clean handover. If you want senior technology judgment around the product afterwards, that is available on a fractional basis. Your choice, not a lock-in.
What you get
- A written specification with acceptance criteria, signed off before any code
- Foundations built for real customers, payments and compliance, not just the demo
- The full build: product, back-office, payments and integrations
- A pre-launch review that tries to break the product before your customers do
- Launch, documentation, handover and a defect-warranty period agreed in writing
- Business model, pricing and go-to-market worked through with you, not left for after launch
Frequently asked questions
What does an end-to-end build cost?
It depends on scope, which is why we start with a fixed-fee diagnosis rather than a guess. You will have a written price against a signed specification before any build starts, and you pay on delivered milestones.
Can you take over a project another team started?
Yes. Project rescue is a growing share of our work. We diagnose what is salvageable, reconcile every earlier decision into one written plan, and rebuild on foundations that can carry the real business.
My prototype was vibe-coded with AI tools. Is it production-ready?
Almost certainly not, and that's fine; that was never its job. The gap shows up in payments, tax, simultaneous users and compliance, exactly the places a working demo never goes. A diagnosis tells you how much carries forward.
How long does a build take?
Weeks, not months. Our most recent rescue went from takeover to launch in five weeks. The timeline for your product is set in the specification you sign off, not estimated on a call.
What makes you different from a software vendor?
Business sense. We build and run businesses of our own, so we work on the business the software has to serve: the model, the pricing, the processes and the go-to-market. A vendor builds what you ask for; we ask whether it will pay, and we say so.
What happens after launch?
You get documentation, training and a defect-warranty period agreed in writing. Many clients keep senior technology leadership around the product afterwards through our fractional CTO service; that is your choice, not a lock-in.
