Back to original languageAbout Louis
👋 3 years ago, I founded Hyperstack to help companies transition to AI.
Since then, I've assisted startups, SMEs, mid-sized companies, and large corporations in identifying high-impact opportunities and building tools that are truly adopted by their teams.
🔄 My methodology:
• Prioritize identifying use cases with the highest ROI
• Use AI only when it brings real value; otherwise, automate, as it's often simpler, more robust, and less expensive
• Support change management, as succeeding in an AI project is as much about people as it is about technology
👉 Major project types:
→ AI & Agents
AI assistants, business copilots, and agents connected to company tools.
→ ERP & Internal Tools
CRM, ERP, back-offices, and custom business applications.
→ Data & Monitoring
Data centralization, pipelines, dashboards, and automated reporting.
💡 Technologies & Partners
Airtable • n8n • Xano • WeWeb • Make • Claude • Hermes • Airbyte • Looker Studio
From audit to production, our goal remains the same: to rapidly build robust solutions that concretely improve how teams work.

Louis is the kind of person you want to work with: everything is organized, fast, smooth. Communication is easy, and the results were largely up to par.
Here, the mission was divided into several "phases", for two reasons:
1) A first reason is the urgency of an upcoming audit, which required initial work.
2) A second reason is the desire to take a step back and observe Louis's working methods before committing further.
One thing is certain: I will formalize the next phases with him.
In short: Great mission accomplished by Louis.

Louis was very professional in his approach: organized, efficient, quickly understanding the stakes, it was easy. He also proposed a solution truly adapted to my needs, beyond the preconceived ideas I might have had initially. The mission completed, we have a whole set of tutorials, explanations of the processes put in place, etc...
I highly recommend ++
