The challenge
Efficient renewals and lasting customer trust
In the vehicle protection market, retaining customers and renewing contracts efficiently determines the health of the operation. Carsystem, a national reference in vehicle protection with tracking among its main services, faced precisely this challenge: manual renewal processes, high operating costs and recurring bans by Meta on unofficial service numbers, damaging the brand’s image with customers. The unpredictability of human operations added variations in service quality and staff turnover costs. Carsystem needed a scalable, effective and secure channel that could integrate naturally with its ecosystem.
Trabbe’s solution
Hyper Agente Caren: intelligent retention on WhatsApp
Carsystem chose Trabbe as its strategic partner. Trabbe designed, developed and implemented Hyper Agente Caren, an autonomous conversational AI agent trained as an expert consultant in retaining customers throughout their protection cycle. Caren operates directly on WhatsApp, already the preferred channel for most of the brand’s customers. It progressed from prototype to go-live in around three months, thanks to Trabbe’s modular architecture and agile integration with Carsystem’s CRM.
Voice and text in a natural conversation
Caren goes beyond reading and writing: it interprets voice messages and responds with natural audio, in a continuous, empathetic dialogue aligned with the brand’s language.
From renewal to payment
It generates and sends payment links directly in the chat and activates specialist subagents across Carsystem’s ecosystem. A single interaction handles everything from renewal to post-renewal details.
Technology, processes and people together
Human agents trained the AI throughout the process, ensuring an integrated experience connected to the realities of the operation.
Proven results
Half the cost and a better experience
The project began in December 2024 and went live after twelve weeks of development. The following results cover the four months after go-live, when Caren delivered concrete results for Carsystem and turned the renewal journey into a strategic asset.
Lower cost, higher satisfaction
Cost per renewal fell by approximately 50% compared with human service, while customer satisfaction (CSAT) exceeded that of the previous human operation.
More conversions and successful payments
Fully serving a dedicated portfolio representing around 20% of the total customer base, Caren already accounts for approximately 60% of the operation’s renewed contracts. Retention conversion rose from around 40% to almost 70%, while payment effectiveness increased from approximately 35% to more than 50%.
Renewals within 24 hours
Most renewals are now completed within 24 hours. Previously, the process took several days and alternated between calls and messages from unofficial numbers.
With lower costs, faster conversion and a better customer experience, the Carsystem and Trabbe partnership has become a national reference in the use of conversational AI agents for customer retention and contract renewals.
