AI agents that answer every lead in seconds (n8n)

What if no lead ever waited for a call back?

For Lumina Énergie, a solar and heat-pump installer, I built two AI agents orchestrated in n8n. Quote requests and support tickets used to be sorted by hand: hot leads waited, answers varied, nothing was tracked.

→ Sales agent: scores every request (hot / cold), writes a summary and sends a personalised email in seconds, then schedules the call back

→ Support agent: answers error codes from the company knowledge base (RAG) and escalates safety issues or refund requests to a human

→ Business rules always win over the AI: a tenant is never pushed as a hot lead, risky advice is blocked

→ Everything is logged in PostgreSQL, workflows are versioned in Git, and a chat bubble plugs into the client's website

Stack: n8n, webhooks, PostgreSQL + pgvector, local LLM (Ollama) or OpenAI, JavaScript, Python, Docker Compose.

Losing leads because nobody answers fast enough? I can set up the same agents for your business (installers, agencies, clinics, e-commerce). Message me and I'll map your first automation for free.
