n8n Agency in France: custom automation and AI agents

Concretely, we take a manual, repetitive process — sorting incoming emails, extracting data from PDFs, following up with prospects, generating reports, syncing two applications — and turn it into an automatic workflow that runs 24/7 with no intervention. n8n is the technical building block; AI (language models) is the intelligence layer we plug into it.

The difference with a simple « Zapier freelancer »: we treat n8n as a production system. Error handling, automatic retries, logging, alerting, GDPR-compliant hosting, staging tests. You keep full ownership of the system and can take it back at any time.

• Data sovereignty. Self-hosted on your infrastructure or a European cloud — nothing passes through a closed US SaaS. Essential in legal, medical and finance.
• Controlled cost. No per-task billing. A modest server absorbs tens of thousands of executions per month at a fixed cost.
• Native AI. Direct connection to Claude, OpenAI, Mistral and vector databases to build agents and RAG pipelines.
• No ceiling. Conditional logic, loops, custom code, more than 400 integrations — where Zapier stops, n8n keeps going.

• Audit & mapping. We identify the highest-ROI processes to automate and cost each piece of work.
• Workflow design. Triggers, API calls, AI steps, error handling, retries — tested in staging.
• Dedicated hosting. Secure self-hosted deployment (Docker, European cloud), backups, updates.
• AI agents & RAG. Connecting Claude / OpenAI / Mistral, vector knowledge bases, autonomous agents.
• Monitoring & maintenance. Alerting, logs, incident fixing, continuous optimization.

Here are automations we regularly deploy for French SMBs and mid-market companies:

• Sorting and auto-replying to incoming emails with an LLM, with human escalation when needed.
• Extracting data from PDFs (invoices, quotes, contracts) into your CRM or ERP.
• Automatic lead scoring and follow-up (see our intelligent real estate CRM).
• Internal chatbot connected to your document base (RAG) to answer your teams' questions.
• Automatic generation and sending of weekly reports from multiple sources.
• Real-time synchronization between applications that do not natively talk to each other.

Two of these deserve their own comparison before you commit to a tool: our guides on document automation software and on AI marketing automation tools lay out where each category actually earns its licence fee.

These building blocks recombine differently by industry. We describe the workflows that actually pay off in real estate agencies, in law firms, in healthcare settings and in HR departments.

Our approach comes in four phases, designed to deliver fast without sacrificing reliability:

1. Audit (1 week). Process mapping, identification of quick-ROI automations, costed estimate.
2. Build (2–4 weeks). Modular workflows and integrations, tested in staging.
3. Deployment (1 week). Self-hosted production rollout with monitoring, alerting and fallback logic.
4. Optimization (ongoing). Monthly review, integration updates, scaling up.
