Constructor

Constructor, headquartered in San Francisco, was founded in 2015 by Eli Finkelshteyn and Dan McCormick to help online retailers improve product search and discovery. The company addresses low conversion rates caused by shoppers failing to find relevant products through traditional keyword search.

Customers include Sephora, American Eagle, Backcountry, and Birkenstock, spanning fashion, beauty, and specialty retail.
