Overview:
Thermeon is a veteran software provider for vehicle hire companies, best known for its flagship CARS+ rental management system. Established in 1967 by Rollo Pickford in Bath, UK, Thermeon long focused on British and Commonwealth markets before expanding globally. Its software suite handles reservations, fleet control, and customer billing for car, van, and truck rental operators. To support international clients, Thermeon established secondary operations in North America and Australia. In November 2018, Thermeon was acquired by Valsoft’s Aspire Software. In October 2021, Aspire unified Thermeon alongside sister portfolio companies Bluebird Auto Rental Systems and Navotar under a single consolidated business entity, Rentall. Today, Thermeon’s CARS+ platform continues to serve multinational rental operators as part of the broader Rentall technology portfolio.
Products and Services:
Thermeon’s products center around the CARS+ enterprise system, which includes modules for branch operations, online reservations, fleet management, and damage/incident reporting. The platform integrates telematics devices, payment gateways, and channel distributors. Thermeon also developed web-based reservation tools (TCAR) and mobile driver/agent integrations. Professional services include client training, system customization, and platform integrations. Following its integration into Rentall, Thermeon products benefit from shared R&D resources across Aspire’s auto rental portfolio.
Geography and Markets:
Originally UK-focused, Thermeon expanded through partnerships and direct offices across Europe, North America, and the Asia-Pacific region. Key markets include the UK, Ireland, Australia, and the Middle East. Thermeon software is widely utilized by medium-to-large vehicle rental operators, independent fleets, and vehicle manufacturers’ rental divisions.
