From Idea to Reality

You have an idea that could change everything, but no clear path to a working product. Or you've already started, but the project has stalled, scope has ballooned, and momentum has died.

Finding the right developer is overwhelming. Agencies quote months and six figures. Freelancers disappear. You're left wondering whether your idea is even technically viable.

The cost isn't just time. It's runway, opportunity, and the risk of never knowing if it could have worked.

The 5-Day Intervention is different.

It removes the friction. One decision-maker. One clear objective. One week. Absolute focus on the critical path. No months of planning. No six-figure quotes. No disappearing freelancers.

Whether you're building from scratch or rescuing something broken, you walk away with either a working product you can demo, or a clear decision about what happens next.

What This Is (And Isn't)

This Is

  • A one-week, fixed-scope engagement with defined success criteria
  • Builds new MVPs from scratch or rescues stalled projects
  • Senior-level execution from day one
  • Designed to produce a working product or a clear decision
  • Complete with walkthrough, handover, and next steps

This Is Not

  • General development work or a replacement team
  • A promise of feature completeness or full product delivery
  • Ongoing support or long-term engagement
  • A cheap option for budget-conscious projects
  • Extensive polish or production hardening

What You Walk Away With

Every intervention ends with one of two outcomes, depending on what the project needs.

Working Product

For new builds and projects ready to ship.

  • MVP built from scratch, ready to demo or test
  • Working prototype proving technical viability
  • Stalled project unblocked and back on track
  • Core feature delivered end-to-end
  • Solid foundation for continued development

Clear Decision & Plan

When clarity matters more than code.

  • Go/no-go recommendation with evidence
  • Architecture direction validated or redirected
  • Technical debt assessment with prioritised remediation
  • Roadmap for next steps with realistic scope
  • Pivot or stop recommendation (if that's the honest answer)

How the Week Works

Six days from kickoff to completion. Structured for momentum and decisive outcomes.

Day 0

Discovery & Scope Lock

We define exactly what we're building and what success looks like. Your idea is translated into a concrete, buildable scope. If there's existing code, access is granted. Success criteria agreed. No ambiguity entering Day 1.

Day 1

Architecture & Foundation

Technical decisions made. Architecture defined. For new builds: project scaffolded, core infrastructure in place. For rescues: codebase assessed, critical path identified. Development begins.

Days 2-4

Build

Focused, uninterrupted development. Core functionality built and integrated. Daily check-ins, if needed, keep you informed. Issues surfaced immediately. AI-assisted where it accelerates delivery without compromising quality.

Day 5

Deliver & Handover

Working product delivered. Full walkthrough so you understand what was built and how it works. Documentation provided. Clear next steps defined. You own everything. Engagement complete.

Is This Right for You?

Who This Is For

  • Founders with an idea who need a working MVP to validate it
  • Non-technical entrepreneurs who don't know where to start
  • Teams with stalled, failing, or over-engineered projects
  • Businesses needing to prove technical viability before investing further
  • Investors or accelerators needing a rapid prototype for due diligence
  • Agencies needing a rescue or expert delivery for client work

Who This Is Not For

  • You need feature completeness, full product delivery, or extensive polish
  • There is no meaningful urgency, and delays carry no real cost
  • Decision-making is distributed across multiple stakeholders or committees
  • The scope cannot be reduced to a single primary objective
  • Cost optimisation is the primary concern rather than speed and certainty
  • You want guarantees without making trade-offs or hard scope decisions
