Dunasys

What Dunasys does

Dunasys is a privately held French engineering company, headquartered in Nanterre and founded in 2006, that designs and supplies embedded systems, telematics hardware, and connected-vehicle software for industrial customers. The firm operates three complementary divisions — Technology, Telematics, and Ingénierie — anchored by an in-house product portfolio of high-precision vehicle dataloggers (Dunalog XL, Dunalog, Dunalog E) and a family of telematics boxes (DCar-S, DCar-E, DCar-E 3W, DCar-BT, Dunaio), supplemented by embedded software and tooling (Stacks/Dunastack, Loganalyzer, Dunagate, Duanacan, Dunadiag).

The Technology division delivers industrial-grade precision dataloggers for vehicle validation and ECU/ADAS testing, supported by a software suite for log analysis, embedded communication stack development, gateway connectivity, CAN bus analysis, and diagnostics. The Telematics division produces telematic devices for fleet management, car-sharing, taxi, and electric-micromobility use cases, including a Bluetooth retrofit product that connects non-connected vehicles to OEM applications. The Ingénierie division provides custom engineering projects and on-site technical assistance, embedding Dunasys engineers inside client development environments. Customers are enterprise OEMs, fleet operators and industrial players in automotive, defense, rail, aerospace, naval, medical, agricultural, and space markets, served primarily through direct enterprise sales.

Dunasys monetizes via hardware sales of its proprietary dataloggers and telematics boxes, one-time software licenses for tools such as Loganalyzer and Dunastack, and professional services for custom engineering projects and technical assistance. Pricing is not publicly disclosed. The firm self-reports products validated over 10M+ km of test operation, 1M+ data points processed daily, and 100+ completed projects. It is privately held with no disclosed external funding, parent company, or institutional investors.

Core offering

Dunasys designs, manufactures, and sells industrial-grade precision dataloggers (Dunalog XL, Dunalog, Dunalog E) and telematic boxes (DCar-S, DCar-E, DCar-E 3W, DCar-BT, Dunaio) for vehicle testing, fleet management, and car-sharing applications, complemented by embedded software tools (Loganalyzer, Dunastack, Dunagate, Duanacan, Dunadiag) and custom engineering services for clients across automotive, defense, railway, aeronautical, naval, medical, agricultural, and aerospace sectors.

Product overview

Dunasys offers a portfolio-based approach with three complementary poles: Technology, Telematics, and Ingénierie. The Technology pole provides industrial-grade precision dataloggers (Dunalog XL, Dunalog, Dunalog E) for vehicle testing, complemented by software tools (Loganalyzer, Stacks, Dunagate, Duanacan, Dunadiag) for data analysis and embedded communication development. The Telematics pole delivers vehicle telematic devices (DCar-S, DCar-E, DCar-E 3W, DCar-BT, Dunaio) for fleet management and car-sharing applications. The Ingénierie pole provides custom engineering projects and technical assistance services. The portfolio operates as interconnected solutions where dataloggers collect vehicle data, software tools process and analyze it, and telematic devices enable real-time connectivity and fleet management.
