The Process

Zero-Risk Methodology

Our pipeline removes assumptions. AI accelerates the research, the design and the code — but every decision still gets validated with real people before we ship it.

Phase 01

Discovery & AI-Assisted Research

We run structured interviews (Jobs-To-Be-Done) to understand your user’s real motivation, and use AI to transcribe, cluster and synthesise what we hear. You get the patterns and the raw evidence, not an AI summary on its own.

Phase 02

Rapid Prototyping

We turn research into interactive wireframes and a scalable Design System in Figma, with AI exploring several directions in parallel. Accessibility to WCAG AA is designed in, not retrofitted.

Phase 03

Empirical Validation

We test the high-fidelity prototype with at least 5 users from your target segment and measure success rates. This is the step AI cannot do for you, and it is the one that removes friction before a line of code is written.

Phase 04

AI-Assisted Engineering

We pick the architecture that fits your timeline, budget and team — not a house stack — and build with AI coding agents under human code review. You ship to production with tests, monitoring and a documented handover.

Digital Ergonomics

Software designed for human brains

Bad UI costs money. We analyze working memory limits, visual perception biases and decision fatigue to design predictable, friction-free interfaces.

FAQ

Frequently Asked Questions

How do you decide which technology my project should use?

You are never sold a stack. After the paid discovery we recommend the option that is most convenient for you — your deadline, your budget, who will maintain it and how fast it needs to change. We explain the trade-offs in plain language and you approve the decision before anything is built. If your existing team already works with a technology, we build on that rather than against it.

Which option suits me: a landing page, a website or a custom platform?

If you need to test whether anyone wants this, start with a landing page — cheapest, fastest, and it gives you a real answer instead of a debate. If you need to be found and generate leads, you want a proper website with SEO and a content structure. If you need to run the business on it — users logging in, paying, managing data — then you need custom software. We will tell you which one you need, including when the answer is the cheapest option.

How long until I see something real?

Discovery and research come first, then a clickable prototype you can actually use, then validation, then the build. The first thing you can put in front of real users is a prototype, not a finished product.

Do I own the code and the intellectual property?

Yes. The code, the design files, the repositories and the accounts are yours from the first commit. We work in your accounts, not ours, so nothing gets held hostage if the relationship ends. Every deliverable comes with the source and the documentation to maintain it.

Do you use AI? Will it replace the team?

We use AI as leverage, not as a substitute for judgement. It speeds up transcription and research synthesis, explores design directions faster, and writes a large share of the boilerplate under human code review. What it does not do is validate your users or sign off on a decision — those stay human. If you do not want AI in your project, tell us in discovery and we scope accordingly.

What happens after launch?

You get a documented handover, a walkthrough of the architecture, and the credentials to everything. After that you can take it in-house, or keep us on a maintenance retainer for monitoring, updates and iterations. We would rather you can leave than feel locked in.

How do we start, and what do you need from me?

The first step is a paid discovery, so the work is properly defined before anyone commits. From there every proposal is custom and follows a diagnosis — we do not publish fixed prices, because the same feature can be a week or a quarter depending on what sits behind it. We need a decision-maker available for roughly two calls per week, plus access to your brand, content and any accounts we must work in.
