Zev began his involvement with hemp in late 2012 shortly after Colorado became the first state to fully allow farmers to grow this versatile crop. He created and was the founding Executive Director of the National Hemp Association, from 2013 to the end of 2016. As a result of his national work with farmers, manufacturers of extraction equipment, lab owners, entrepreneurs, and buyers of hemp products, he has developed long-standing relationships with many of the major suppliers in the U.S. hemp industry.
In 2017, he created the Hemp Marketplace, which has grown to become the largest and most active hemp marketplace in the world. Zev also founded Herb-a-lites, a wholesale and retail brand for raw hemp products such as flower, pre-rolls, hemp tea, and seasonings. He is the Chief Operating Officer of Abraham Paiss & Associates, Inc., which focuses on building a sustainable U.S. hemp supply chain.
