Kathryn Schifferle of Work Truck Solution is Recognized Among 100 Leading Women in the North American Auto Industry by Automotive News
Work Truck Solutions’ Founder and Chief Vision Officer, Kathryn Schifferle, has been named among 100 Leading Women in the North American Auto Industry by Automotive News. Schifferle and her co-honorees were celebrated at The Henry in Dearborn, Michigan, with a gala hosted by Automotive News. They were also featured in the May 19 issue of the magazine.
100 Leading Women in the North American Auto Industry recognizes women who lead in the automotive field. It recognizes those who are influential and pivotal to their companies and the industry. Automotive News has published the list of the industry’s top female executives every five years since 2000.
With a background in strategic business development, Schifferele has expanded Work Tuck Solutions’ influence in the commercial vehicle sector with Comvoy. Comvoy was built to help buyers find the right vehicle at a dealership for their business while simultaneously assisting dealerships with merchandising their inventory and expanding their reach.
Schifferle has also spearheaded numerous innovative projects supporting the evolving needs of businesses in the transportation sector. One of the most recent examples is the Commercial Electric Vehicle (CEV) Hub, a resource developed in collaboration with J.D. Power. CEV Hub provides businesses with interactive tools and insights to assist with fleet electrification, including available tax incentives, total cost of ownership calculations, and EV charging infrastructure mapping and matching.
Schifferele commented on the recognition, saying, “Being recognized among the industry’s leading women is truly an honor, but more importantly, it underscores the progress we’re making in reshaping the way businesses interact with commercial vehicles. Work Truck Solutions and Comvoy have always been about innovation, ensuring that dealers, fleet managers, and business owners have the right tools to thrive in an evolving landscape. As we continue to drive forward, I’m excited to be a part of how collaboration and technology are shaping the future of mobility."
The 2025 class of Automotive News’ 100 Leading Women in the North American Auto Industry emerged from a months-long nomination and judging process that attracted hundreds of entries from the United States, Canada, and Mexico.
