What does a CEO actually do all day? In this episode of Explain It to a Teenager, teen host Jensen Muller sits down with Mark Zagorski, CEO of DoubleVerify, the company fighting digital ad fraud across platforms like TikTok, Meta, ETC. From smart fridges running fake ads (seriously) to bots trying to scam billions of dollars, Mark breaks down how his team keeps advertising real, relevant, and safe—and why it matters to everyone who uses the internet. He continues to talk about the trials and tribulations of being a CEO in a public company that saves people tens, if not hundreds, of millions of dollars, and how every day is different.

How does a professional tennis player balance entrepreneurship and helping 10,000 kids per year? Sloane Stephens does it all and explains it to teenager Jensen Muller. While Sloane is known by most as a professional tennis player (with a Grand Slam title under her belt), she is also the founder of two companies, Doc & Glo and the Sloane Stephens Foundation. Doc & Glo is a body care brand that is named after her grandparents, and in her words, "based on wellness, self-care, [and] self-expression." The Sloane Stephens Foundation is a non-profit that serves around 10,000 kids per year in the Compton Unified school district. Big thanks to Sloane Stephens for sitting down with us to share what you do, and please enjoy the video. Explain it to a Teenager takes big, complicated topics and explains them in simple, clear ways that anyone can understand. #explainittoateenager

Mark explained what it’s like to be a CCO at an ad measurement company, what an ad measurement company is, and what iSpot does, all in detail. Not sure if I even have to say it, but give it a watch!
