[ 01 ]Services

Three ways to begin.

Every engagement starts with a conversation and a brief. From there, the work takes one of three shapes.

01Build

Product, end to end

From an empty repository to a product in real users’ hands — six to twelve weeks, engaged for equity or a fixed fee.

06 – 12 weeks↗

02Audit

An honest read on AI

A two-week diagnostic. Where AI moves the needle, where it quietly doesn’t, and a roadmap with no theatre.

02 weeks↗

03Workshop

Build alongside your team

Two to five days, hands on. Your team leaves having shipped something real — and knowing how it was done.

02 – 05 days↗

[ 03 ]Approach

Ship first.
Talk later.

Four principles the studio holds to — on every engagement, without exception.

— 01

Ship, then talk.

A working product by the second week. Every conversation after that is about something real, not a slide.

— 02

AI only where it earns its place.

It is a material, not a mission. When it is not the answer, you hear that plainly and early.

— 03

One person, the whole way down.

No account layer, no handoffs. The person you brief is the person who designs, builds and ships.

— 04

Built for month six.

Made for the team still shipping long after launch day — not for the demo that looks good once.

[ 04 ]The Studio

Julien Poulain, founder of Axyom Studio — Julien PoulainFounder

Built end-to-end
by one person.

I’m Julien — twenty-five, French, based in Seoul. I came up through enterprise sales at BASF, learning how real companies buy, decide and stall. Then I started building.

I co-founded Cazen, shipped Axyom solo, and contracted on AI work that moved a company’s valuation. Axyom Studio is one person accountable for the whole outcome — strategy, design, engineering, and the ship.

[ 05 ]Frequently Asked

Questions,
answered straight.

Usually with a short call and a written brief. From there we scope one of three formats — a Build, an Audit, or a Workshop — and agree a start date. Most teams begin with an Audit or move straight into a Build.

[ 06 ]Start a project

Let’s build something
that ships.

The fastest way in is a conversation. Book a 30-minute call — bring the problem, and we’ll work out whether a build, an audit, or a workshop is the right first move.
