Who We Are

CMT is committed to providing opportunities and career growth to the underrepresented. We're focused on creating an inclusive work environment that encourages a diversity of backgrounds and thought to produce the best products and services within our industry.

CMT’s story begins at MIT

In 2004, Hari Balakrishnan and Sam Madden started the CarTel project at MIT, developing a mobile sensing system to collect and draw inferences from sensor data on mobile devices. The following years, they partnered with Boston taxi companies to accurately measure traffic surface conditions and traffic using award-winning new methods for mobile telematics. This research won multiple “best paper” and “test of time” awards from the top research conferences in Computer Science. In 2010, building on their academic success, they started Cambridge Mobile Telematics with Bill Powers.

Cambridge Mobile Telematics (CMT) is the world’s largest telematics service provider. Its mission is to make the world’s roads and drivers safer. The company’s AI-driven platform, DriveWell®, gathers sensor data from millions of IoT devices — including smartphones, proprietary Tags, connected vehicles, dashcams, and third-party devices — and fuses them with contextual data to create a unified view of vehicle and driver behavior. Companies from personal and commercial auto insurance, automotive, rideshare, smart cities, wireless, financial services, and family safety industries use insights from CMT’s platform to power their risk assessment, safety, claims, and driver improvement programs. Headquartered in Cambridge, MA, with offices in Budapest, Chennai, Seattle, Tokyo, and Zagreb, CMT serves millions of people through over 95 programs in 25 countries, including 21 of the top 25 US auto insurers.
