Car dealerships: an AI agent to sell financing

Where the margin is made

At a dealership, the margin isn't only made on the vehicle: financing matters too. Yet salespeople are car experts, not financial product experts. Facing a customer torn between leasing options and a classic loan, many prefer not to go there.

Max, a financing expert beside every salesperson

For Prêt Lease, a car financing broker, I designed Max: an AI assistant that masters financing offers and answers salespeople by voice or in writing.

• Real-time voice conversation, with latency under 300 ms.
• Knowledge base (RAG) built from lenders' documentation and internal training material.
• Pre-assessment of the customer's file with deterministic scoring, to avoid guesswork.
• Continuous training module to upskill the sales team.

“We were looking for a way to boost our sales at Prêt Lease: the AI agent Bilal built had an immediate impact.”

— Gaetan Vanacker, founder of Prêt Lease

Key takeaway

A good business agent doesn't replace the salesperson: it fills exactly the skill they're missing, when they need it, in front of the customer.
