Prototype Your Idea

Turn ideas into working systems in days, not months, with open-source-first prototype sprints.

Prototype Your Idea

Turn ideas into working systems in days — not months.

Most ideas die in documents.

A briefing gets written.
Slides get prepared.
Meetings get scheduled.

Weeks pass before anything is actually built.

There is a better way.

Prototype first.

Instead of explaining ideas, we build them.
Instead of debating assumptions, we test them.
Instead of asking stakeholders to imagine something, we let them use it.

Why Prototyping Works

A working prototype communicates better than any document.

When people can click, test, and experience an idea, decisions become easier.

Prototyping helps you:

  • validate ideas quickly
  • align teams and stakeholders
  • convince investors or boards
  • test technical feasibility
  • explore new business models
  • discover risks early

With modern tooling, APIs, open-source repositories, and AI-assisted development, what used to take weeks can now be built in days.

Open Source First

All prototypes are built using open-source technologies whenever possible.

This means:

  • your intellectual property stays yours
  • your business logic isn’t trapped inside someone else's platform
  • you avoid vendor lock-in
  • the prototype can evolve into a real product
  • everything can run locally or inside your own infrastructure

Open source protects your independence and ensures the prototype remains something you own.

Prototype Timeline

A typical prototype sprint can be completed in a few days.

Day 1 — Idea & Scope

Define the core idea and identify the smallest experiment worth building.

Day 2 — Architecture

Select tools, APIs, and open-source components. Design the technical approach.

Day 3 — Build

Develop the working prototype and connect the systems.

Day 4 — Test & Iterate

Validate assumptions, explore improvements, and refine the prototype.

Day 5 — Delivery

You receive the working system, the codebase, and recommendations for next steps.

Starting at €5,000

You don’t need a full development team to explore an idea.

Prototype Sprint — starting at €5,000

This includes:

  • idea scoping
  • architecture design
  • prototype development
  • delivery and walkthrough

You walk away with:

  • a working prototype
  • real technical insight
  • something you can show investors or stakeholders
  • a clearer path forward

My Three Pillars

Prototype Everything

Ideas shouldn’t live in documents.

Automate Early

Automation and AI should be part of the architecture from the start.

Open Source First

Own your infrastructure and protect your intellectual property.

Let’s Build Something

If you have an idea you want to explore, the fastest way to understand it is to build the first version.

Sometimes the result becomes a product.
Sometimes it reveals a better idea.

Either way, you move forward faster.

Start with a prototype.

If you want to explore this for your company, send a quick note and we'll map the best next step together.

I'm looking forward to exploring your ideas! Seb
