AI where it helps.
A human where it counts.
Not a cheap agency, not an autonomous app generator, not a fictional dev team. Costs come down through smart scoping, automation and low overhead — never by skipping tests or diluting responsibility.

How it works
Four steps. No surprises.
You see a range in minutes. The final price and start date only follow a human review of your scope.
STEP 01
Describe & clarify
Tell us the idea or the painful process. A few targeted questions — never the same one twice.
STEP 02
Get a range, request a review
An instant AI-assisted range with inclusions, exclusions and assumptions. Ask for a human review when you're ready.
STEP 03
Approve the quote
Scope, milestones, acceptance criteria and price — confirmed before any deposit.
STEP 04
Build & ship
Development with regular check-ins, tests, deployment and handover of the source code.
AI-assisted estimate. Not a final quote — a human signs off before anything starts.

Leave with a clearer plan.
Each tool answers one real decision and gives you something reusable — even if you never become a client. Your brief carries over from one tool to the next.
Startup Pressure Test
What has to be true for this idea to be worth building? Honest, nuanced — it may even tell you not to build yet.

What should you build first? Sort features into Keep, Later and Remove — then re-estimate the leaner version.

App Blueprint & First Screens
Screens, components, data and navigation — validated as a plan first, then a first mockup of your main screen.

Idea-to-Landing
Structured copy, sections and a responsive preview of a validation page — to test demand before you build.

Real products.
Real scope.
Case studies show the problem, the scope, screenshots, Romain's role and what was delivered — with personal projects labelled as such. Full write-ups are being prepared; ask for a walkthrough in the meantime.
Services & pricing
Simple offers. Honest ranges.
Every quote spells out what's included, what's excluded, the estimation method and the final deliverable. Hosting is always separate from the initial build.

FAQ
Straight answers.
Help before selling. Clarify before building. Human validation before commitment.
How fast can you deliver?
It depends on scope — there's no universal "7 days" promise. Your quote lists milestones and an indicative timeline, confirmed during the human review.
How exactly do you use AI?
AI accelerates drafting, scaffolding and repetitive work. Romain owns scoping, architecture, integrations, code review, tests and delivery. Nothing ships without human review.
Do I get the source code?
Yes. Code delivery and commercial use are set out in the contract, alongside any obligations from third-party licensed components.
What if my scope changes?
Changes follow a clear change procedure: we re-scope and issue a new quote version. An accepted quote is never modified silently.
Is the instant estimate a real quote?
No — it's an AI-assisted range with explicit assumptions. You can request a human-reviewed quote, which confirms feasibility, exact scope, availability and conditions.
Is my idea kept confidential?
Private results are never indexed. Don't share secrets or API keys in the tools — and you can export or delete your brief at any time.
