Welcome to the 2018 Power 50 list, which ranks the most influential people in the industry.

#15 Jonathan Isaacson, Gemline (asi/56070)

2017 Rank: 15
Title: President
Industry Experience: 30 years

Peers consider Isaacson one of the industry’s smartest people, an issues and trends wonk who closely studies the market and tells it like it is. His late 2017 deal with fast-growing RuMe was a coup, giving his supplier another major brand to exclusively sell. Isaacson would undoubtedly be higher on our list if it weren’t for Gemline’s 1.9% average annual growth over the past five years.
