Sr. User Acquisition Manager

What is Fizz Fizz is the hottest Gen Z social platform in the world. Having started as America’s biggest college social app, Fizz is now allowing Gen Z globally to connect around their shared experiences and identities. College Fizz communities feature a private, moderated feed of posts from verified students, making it the most entertaining and authentic way to experience student life. Our newest product, Global Fizz, brings together all of Gen Z both domestically and abroad, providing a space to satisfy the 99% of life not on entertainment platforms like Instagram and TikTok. Fizz is on a mission to bring social back to social media.   What We've Done We first launched Fizz at Stanford in July 2021 and have since seen >95% of undergraduates join the app, half of which use Fizz every day. Since raising a $25M Series B in July 2023, we have established ourselves as the dominant social app at 700+ colleges, have begun to generate revenue through advertising, and are actively expanding to communities beyond college. Most recently, Fizz hit #1 overall on the App Store charts in Saudi Arabia.   Where We're Going We have three primary goals for 2026: continue our expansion to the entire US college market, drive revenue growth through our revolutionary ads business, and rapidly expand to non-college students — both domestically and abroad.
