How ADD Automotive Began
ADD Automotive was established in April 2021 during a period of economic uncertainty following the COVID-19 pandemic.
Brad and Jennifer recognized the growing problem of catalytic converter theft and the financial burden it placed on vehicle owners.
Combining Brad's automotive manufacturing and mechanical expertise with Jennifer's digital design, marketing, and business experience, they developed ADD A CAT catalytic converter shields.
Their goal was to create a durable, practical, vehicle-specific anti-theft solution that offered substantial coverage without complicated installation requirements.
From the beginning, the company emphasized American manufacturing, thoughtful product engineering, and direct customer support.
Today, ADD Automotive continues to expand its product offerings while remaining committed to those founding principles.
