The former chief revenue officer of TV and digital platform Amobee founded Fyllo in 2019 to help cannabis companies manage marketing, analytics and regulatory compliance—and to help mainstream brands reach cannabis users.

This year, Bronstein, 34, has completed a $30 million Series B funding round for Fyllo, acquired customer relationship management platform DataOwl and presided over 32% revenue growth.

Bronstein is also a strategic advisor at OpenWeb and executive chairman and co-founder of Wesana Health, which specializes in treating traumatic brain injuries and went public. And he’s on the board of fitness marketer Cityrow. He’s helped those three companies raise another $60 million combined this year.

But his biggest impact is with Fyllo, which is in the process of hiring 70 people globally and has seen sales rise 32% over the past 12 months from dispensaries and consumer marketers such as Clorox Co. and Uber.

While dispensaries need Fyllo software to help keep up with “hyperlocal regulations,” Bronstein says, mainstream brands want to understand and reach hard-to-target cannabis users. “Why wouldn’t Uber Eats want to target you [with ads for a snack] if you’ve been smoking?” he asks.
