What you can hire me for

Focused engagements for teams that need to move from vague AI opportunity to usable software.

01 / AI Product Sprint

AI Product Sprint

Best for

You have a workflow or product idea and need a working prototype fast.

Output

Clickable product, technical plan, and next-step roadmap.

02 / MVP Build

MVP Build

Best for

You need a real v1 shipped end-to-end.

Output

Designed, built, deployed product with handover.

03 / AI Workflow Audit

AI Workflow Audit

Best for

You suspect AI can improve an internal workflow but do not know where.

Output

Opportunity map, build/no-build recommendation, and prototype scope.

What it does

Axyom Studio is a one-person applied AI product studio in Seoul. The studio designs, builds, and ships production-grade software for founders and small teams, applying AI only where it improves an existing workflow.

Who it is for

Founders, operators, product leads, and small teams who need working software, not strategy decks. The fit is sharp when there is a real workflow to improve, a real user, and a real decision to make about whether AI belongs in it.

[ 04 ]Who this is for

You brief the person who ships.

No account manager, no handoff, no translation loss. Strategy, product design, engineering, launch, and iteration stay with one accountable person.

Good fit

  • Founders with a sharp product bet
  • Small teams with a real workflow
  • Product leads who need a prototype or v1
  • Operators who want AI where it earns its place

Bad fit

  • Vague AI exploration
  • Chatbot wrappers without a workflow
  • Slide-only strategy
  • Large procurement cycles with too many stakeholders
[ 05 ]Process

How we work

Fast enough to learn quickly. Structured enough to survive past the demo.

  1. WEEK 0

    Brief

    One problem, one user, one workflow.

  2. WEEK 1

    Prototype

    A working interface or technical proof, not a deck.

  3. WEEK 2

    Decision

    Kill, narrow, or commit to build.

  4. WEEKS 3–8

    Build

    Design, engineering, AI integration, deployment.

  5. MONTH SIX

    Still usable

    Documentation, handover, observability, and iteration path.

[ 06 ]Production

Built for production, not demo day

  • AI is used only where it improves the workflow.
  • Model behavior is tested against real use cases.
  • Every build includes handover notes and deployment documentation.
  • No black-box dependency without a fallback plan.
  • Data handling is defined before anything gets built.
[ 07 ]The Studio
Julien Poulain, founder of Axyom Studio
Julien PoulainFounder · Seoul

Built end-to-end
by one person.

Came up through enterprise sales at BASF (2022–2025), learning how real companies buy, decide and stall. Then started building. Twenty-five, French, based in Seoul.

Co-founded Cazen. Shipped Axyom solo. 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.
