Services / Idea to Functional Prototype
IDEA → FUNCTIONAL PROTOTYPE

Turn one important idea into working software in three days.

You bring the business problem and access to the person who understands it best. We bring a senior AI-native product engineer and a disciplined three-day build process. Together, we choose the one workflow the first version must prove, translate the domain knowledge into users, rules, data and actions, and start building on Day 1. By the end of the sprint, you have functional software you can put in front of stakeholders—not another document describing what someone might build later.

PRODUCTIZED STARTING POINT

3-Day Idea Sprint

Choose one important product idea or business workflow. In three focused days, turn it into functional software that can be used, demonstrated and evaluated.

£2,500fixed · 3 days

Best for one core workflow with a clear user and outcome. The sprint is intentionally bounded so speed stays credible. It is a functional prototype and decision-making asset—not a promise that an entire production platform fits into three days.

WHAT YOU LEAVE WITH

Not a slide deck. A working artifact you can make decisions with.

The exact deliverables depend on the idea, but the sprint is designed to leave you with something concrete enough to show users, executives, partners or investors—and useful enough to inform the next engineering decision.

01Functional prototype

A usable implementation of the agreed core workflow—not only static screens or a clickable mockup.

02Source code

The code produced during the sprint is handed over so the work can be continued rather than trapped inside a demo.

03Deployed preview

Where practical, a working environment that stakeholders can access without setting up a local development machine.

04Documented assumptions

The business rules, product decisions, unanswered questions and constraints surfaced during the sprint.

05Product + technical walkthrough

A clear explanation of how the prototype works, what is real, what is simulated and what would change for production.

06Production roadmap

Recommended next steps, likely engineering priorities and a scoped path into a Launchable MVP or larger production product.

WHY IT MATTERS

The fastest way to understand a software idea is to use it.

A new software idea is usually full of hidden decisions. Who exactly is the user? What information do they already know? What has to happen first? Which rules are mandatory and which are preferences? What happens when the normal path breaks? Those questions are difficult to settle in the abstract because people often discover what they mean only when they can see and use the workflow.

Our process is designed around that reality. On Day 1, the person who knows the domain works directly with the engineer who will build the product. They identify the user, the business outcome, the core journey, the data that moves through it, the important rules and the exceptions worth representing. The engineer starts translating that understanding into the application immediately.

As the software takes shape, the domain expert reviews the real behavior—not a specification passed through several layers. Questions are resolved against the product while they are still inexpensive to change. AI agents give the engineer additional execution capacity for scaffolding, tests, refactors, investigation and documentation, but the senior engineer remains responsible for the implementation and technical choices.

By Day 3, the goal is not to pretend the product is finished. The goal is to have enough working software to make a high-quality decision: continue, change direction, expand the workflow, integrate real systems, or move into production engineering.

WHAT WE CAN DO

Everything required to turn one workflow into something real.

The exact stack follows the problem. The sprint combines product thinking, domain input and enough engineering depth to make the first version genuinely useful—not merely attractive.

01Product and workflow discovery
02Subject-matter expert participation
03Rapid UX and interaction design
04AI-assisted full-stack development
05Claude, Codex and coding-agent workflows
06Database and API scaffolding
07Real data or integration proof points
08Automated tests for critical paths
09Fast stakeholder feedback cycles
10Architecture path from prototype to production
HOW WE WORK

Three days. One focused workflow. A visible result every day.

01

Before the sprint — confirm the target

We run a short fit and scoping conversation to make sure the problem is bounded enough for a three-day build. We agree on the primary user, the business outcome and the one workflow the sprint will focus on. This prevents a “prototype” from quietly becoming an entire platform.

02

Day 1 — model the business and start building

The domain expert and engineer work through the real process: inputs, decisions, roles, rules, exceptions and the desired result. The engineer turns that model into the first screens, data structures and application flow the same day. By the end of Day 1, there should be software to react to.

03

Day 2 — make the core journey usable

The engineer deepens the workflow, connects the necessary data or APIs, and uses AI agents for parallel implementation, test creation and technical analysis. The domain expert reviews what is working, corrects assumptions and answers the questions the product surfaces.

04

Day 3 — refine, demonstrate and hand over

We close the most important gaps, test the core path, prepare a usable demonstration or preview, and walk through the product with you. You receive the source code, the working prototype, the decisions and assumptions we discovered, and a clear recommendation for production, further validation or the next build stage.

GOOD FIT WHEN

A good fit when you need evidence before you need an organization.

A founder has a product idea but no engineering team
An executive wants to digitize a manual or spreadsheet-based process
A business unit wants to test a new internal application
A subject-matter expert knows the workflow but needs a technology partner
A product team wants a working proof before committing a larger budget
DIRECT ANSWERS

Questions buyers usually ask.

Do we need complete requirements before the sprint?+

No. We need enough clarity to identify the user, the core workflow, the business outcome and the main constraints. The point of the sprint is to use working software to expose the requirements that are difficult to discover in documents alone.

Who is the subject-matter expert?+

The domain knowledge can come from your organization—a founder, operations lead, product owner or specialist who knows the workflow—or from a specialist we bring in where that is appropriate. The important principle is that domain knowledge works directly with engineering rather than being translated through layers.

Is the result only a visual prototype?+

No. The target is functional software. Depending on what the idea needs to prove, the sprint can include a real backend, database, authentication, APIs, sample data or a limited integration. We agree on those proof points before the sprint starts.

Can this become the production product?+

Often, yes—but not by pretending a prototype already has every production concern solved. We keep sound work, then add or refactor architecture, data integrity, security, permissions, testing, deployment and observability as the product moves into the next stage.

What if the idea is too large for three days?+

We reduce it to the smallest workflow that proves something important. If the first useful slice cannot be responsibly bounded, we recommend a different engagement rather than forcing the work into a three-day promise.

IDEA TO FUNCTIONAL PROTOTYPE

Have a business idea that deserves to become real software?

Bring the problem and the person who understands it. We will turn one focused workflow into working software and give you a clear basis for the next decision.
