Automobile injuries and crashes — 50 million annually — are a serious worldwide problem. At Cambridge Mobile Telematics (CMT), our mission is to make the world’s roads safer using mobile sensing and IoT, machine learning, and behavioral science. We have developed DriveWell, a complete telematics and behavioral analytics solution, to improve safety for the connected car world. DriveWell provides actionable insights on driver behavior and vehicle dynamics to auto insurers, fleets, auto makers, wireless carriers, and government agencies, and is being used successfully by over 25 customers on 6 continents.

Founded in 2010 by two MIT professors and experienced entrepreneurs, CMT pioneered telematics for behavior-based insurance (BBI) and deployed the first solution to provide both traditional vehicle-centric UBI and BBI. With over a billion miles of driving data, CMT has a proven record of changing driver behavior: an average reduction of 35% in phone distraction, 20% in hard braking, and 20% in at-risk speeding all within less than 30 days of using the program. With DriveWell, insurers report fast customer growth (e.g., 2x growth rate compared to earlier), lower loss ratios (e.g., 34% lower crash rates, 19% less-severe claims, and 10% lower loss ratio compared to blackboxes), and greater customer retention rates.

We have an outstanding team of experts in mobile sensing and IoT, machine learning, big data analytics, and statistics. We work on several innovative technologies and products that are changing the insurance and connected-vehicle ecosystem:

Accurate inference of vehicle dynamics and driver distraction from mobile device sensors in arbitrary and changing orientations

Best-in-class battery-efficiency combined with best-in-class trip recording accuracy and precision telematics

Powerful behavior feedback and incentives to improve driver safety while increasing user interaction and engagement

Special features for vehicle fleets to optimize fleet utilization, safety, and productivity

Accurate assessment of predictive risk factors and customizable scoring models based on billions of miles of data and a multitude of real-world crashes

Innovative place-and-go wireless IoT device to augment smartphone sensors, providing accurate scoring even when phone is absent

Behavioral analytics that automatically infers “driver” vs. “passenger” trips as well as other modes of transportation

Accurate crash detection and robust crash forensics

Leadership Team

Bill Powers

Founder & Chief Executive Officer

Bill has played a vital role in building and managing a number of successful organizations at companies like Swoop and As EVP/Sales at, his efforts shaped a sales organization that led to the company’s acquisition by NAVTEQ, and, subsequently, Nokia. He is recognized as a leader in emerging media and technology. He is a past member of the Sales Executive Council of the Interactive Advertising Bureau (IAB). Additionally, Bill established the Luke Vincent Powers Foundation in memory of his son, Luke. He serves as the Foundation’s President, which supports disadvantaged children.

Hari Balakrishnan

Founder & Chief Technology Officer

Hari led the MIT CarTel project with Sam Madden, developing several award-winning papers and technologies that were the academic origins of Cambridge Mobile Telematics. He is also the Fujitsu Professor of Computer Science at MIT and a Director of Wireless@MIT. Before CMT, he co-founded StreamBase (acquired by TIBCO, was a founding advisor to Meraki (acquired by Cisco), and contributed to Sandburst (acquired by Broadcom), all MIT spin-offs. He was elected to the National Academy of Engineering in 2015.

Sam Madden

Sam Madden

Founder & Chief Scientist

In addition to co-leading the CarTel project with Hari Balakrishnan, Sam is a Professor of Computer Science at MIT and the Director of BigData@CSAIL, an industry-university collaboration to explore issues related to managing data that is too big, too fast, or too hard for existing data processing systems to handle. He is known for contributions to the field of database systems, including widely cited papers on topics related to managing sensor data, column-oriented databases, and databases-as-a-service and was a co-founder of Vertica (acquired by HP).
