Advanced Stack explained the difference between ChatGPT and other agents IA.

Advanced Stack is an independent AI advisory in Paris. One practice, one principal, no vendor ties. We exist for one reason: companies are spending millions on AI without knowing what to do first, in what order, and why. We answer that question - with working systems, not decks. How it works: The demo (free, 45 minutes). A working system on your own data and processes. You leave knowing what's possible, in plain language. No pitch, no obligation. The business proposal (paid, ~2 weeks). An audit of your processes, prototyped and stress-tested before a single recommendation. You leave with a sequenced roadmap and a plan for phase one - a consulting deliverable you own. The transformation (ongoing). A relay that owns your AI agenda - strategy, prototypes, agent systems, and the training that makes it yours. Exit criterion, written into the engagement: your team runs it without us. How we work: - Prove before promise. Prototypes run long enough to see what breaks. - Reports, not slides. Research-grade documentation you can actually use. - No vendor alignment. We work for you, not for an AI platform. - Independence over dependence. Your infrastructure, your data, your keys. If we leave, the systems stay. Proof, plainly: - Twenty years of translating technology: taught computer basics to retirees; led a 15-person software house shipping secure systems for Orange/Globecast and EDF. - Working with a fast-growing executive-search firm since 2023, and a second, currently confidential client. - Public research & field notes: real experiments, failure analyses, evaluation data. Who we work with: fast growing companies where the AI agenda needs an owner and a sequence. Who we don't: cost-cutting projects. Pure execution. Lock-in deals. AI is how you grow — and how you keep the human touch that is your actual product. We break it so you don't have to.
