About Julian

Senior AI Architect & Service Designer.I design and deliver AI agents that understand your business — and that work in production.
15 years designing products (ROLI/Apple Store, EY, Prisma Media/Vivendi, mySofie/AG2R), then co-founder of an AI startup whose products are used daily. I am at the rare intersection of two fields that the market separates: service design (mapping your business, formalizing your expertise) and AI engineering. Developers code without diagnosing, consultants diagnose without delivering.I do both.
Agile, concrete, immediately:I am the bridge between business, design, and tech. Not an agency with its chain of intermediaries, not a vibe-coder who delivers a demo to be thrown away, not a consultant who stops at the slide. I use AI to build your AI: what used to take months is now delivered in days — often 5 to 10x faster and 3 to 4x cheaper than an agency, for an operational result.
My method, in 5 steps:
1. Listen— I map your actual business (service blueprint).
2. Shape— I formalize your rules, your cases, your tone: an asset you keep, even without me.
3. Build— your platform and your online assistants, in days not months.
4. Activate— we test on your real cases, I adjust, I train your team.
5. Grow— I remain a partner after launch, without a subscription.
For professions with high expertise (Financial Advisors, lawyers, accountants, consultants, coaches), SME leaders, and idea holders.
Serious & compliant: 4 years in regulated health, systems processing minors' data (CNIL PIA), European hosting, GDPR. I also teach AI and service design at Gobelins School.
Each mission starts with a 30-minute discussion. If AI isn't the right lever, I'll tell you.
