Outsourced Receptionist
Third-party operators answering your dealership phone. They know cars exist, but not your stock, your workshop schedule, or your DMS. Average cost: $2,000-4,500/month. They read from a script and take messages. Most calls require a callback anyway.
Suited for dealerships wanting a human voice regardless of efficiencyDealer Phone System
Your existing PABX or VoIP system with auto-attendant. Press 1 for sales, press 2 for service. Routes calls but qualifies nothing. After-hours, it goes to voicemail — which 80% of callers do not leave. Cheap to run, expensive in missed opportunities.
Suited for basic routing during business hoursDiago
AI voice agent specialized for car dealerships, founded in 2023 in Paris. Raised €1M in July 2025 backed by GP Mobilians (according to press coverage). Deployed in 30+ dealer groups including Mary Automobiles (according to their website). Handles 80,000+ calls per month. Specialized in workshop scheduling, DMS integration, and automotive-specific vocabulary.
Suited for dealerships with high workshop call volumeAI Voice in Automotive: 2026 Landscape
The automotive sector was slow to adopt AI voice. By 2026, two dedicated players have emerged in France: Diago (workshop-first, DMS-native) and Natalia (full dealership phone, multichannel). Generic voice AI platforms also serve automotive but lack DMS integration and auto-specific vocabulary.
Natalia covers the entire dealership phone: sales inquiries, service scheduling, general customer service, and web lead follow-up — with WhatsApp and SMS built in.

What makes Natalia different from Diago
Full dealership phone, not just workshop
Diago excels at workshop scheduling. Natalia handles everything: sales inquiries, service booking, general customer questions, and web lead follow-up. One AI for the whole dealership, not just the service department.
WhatsApp and SMS after every call
Every call triggers a WhatsApp summary within 10 seconds. 45% response rate (internal data). For dealerships, this means test drive confirmations, service reminders, and quote follow-ups — automatically.
48-hour pilot, transparent pricing
Running in 2 days, starting at $299/month. No multi-week integration project. Natalia connects to your existing CRM and phone system without touching your DMS if you prefer.
Not locked to automotive
Natalia works across sectors. If your group also runs rental, insurance, or other businesses, the same platform covers all of them. Diago is automotive-only — great focus, but limited if you diversify.
How to Choose Between Natalia and Diago
Choose Diago if workshop scheduling is your number-one problem and you need deep DMS integration (native connection to your dealer management system). Choose Natalia if you need full dealership coverage (sales + service + customer follow-up) with WhatsApp/SMS multichannel.
For large dealer groups with a dedicated DMS workflow and high workshop call volume, Diago's specialization delivers real value. For dealerships wanting a single AI that handles every call type and follows up across channels, Natalia is the broader solution.
When Diago Is the Better Choice
Diago has a clear edge on DMS workshop integration and automotive vocabulary. If 90% of your calls are workshop-related — scheduling, service follow-up, parts ordering — Diago is probably the better pick. Their native DMS connection means workshop appointments land directly in your system without middleware. Natalia brings multichannel (voice + WhatsApp + SMS) and covers other dealership needs (sales, general customer service, web leads). If your calls are diverse, Natalia handles the full spectrum.
