March 18, 2014—The Specialty Equipment Market Association (SEMA) Data Co-op announced Friday that it has hit 600 members, a 300 percent increase from August of 2013.

The organization’s membership is made up of automotive suppliers and resellers worldwide, who represent a $31 billion share of the automotive aftermarket industry.

The Data Co-op credits much of its growth to the launch of its Product Information Management System in May 2013 and the announcement last fall of free product data exports to SEMA members.
