Zac Stern — Co-Founder

My first words at age 2 were “ARR” and “synergistic cross-functional deliverable-driven performance ecosystems,” according to my mother. I started my professional career as the youngest VC at Rosecliff Ventures. After a couple years into the VC world I realized I wanted to build my own company and settled on a relationship building app called Official. After launching on Valentines Day 2022, our in-house team produced viral videos through a specific formula that netted 110M+ views within just 6 months. We were the fastest growing relationship app at the time with over a million couples signed up. Official was acquired by Bumble in 2023. Founded Undisclosed Group in 2024 as a hybrid of investments and incubation with a strong focus on Gen Z brands and cutting-edge marketing strategies. Co-Founded Golden Egg Media, a media agency dedicated to making its clients go viral across X, LinkedIn, Instagram and Tiktok as well as advise VC’s, brands and other agencies.
