Alex Halperin is a Loeb Award–winning journalist and media entrepreneur. He founded WeedWeek in 2015 and built it into a leading B2B publication before selling it in 2025.

After years of selling sponsorships, he founded Cohorta because publishers deserve to be paid for the people they reach, not their list size.
