Fizz runs verified, hyper-local campus communities on 700+ US college campuses, applying LLMs, vector databases and machine learning to a growing social platform.
Fizz is a social media platform for college students, offering hyper-local, verified campus communities where users post questions, memes, polls and conversations while controlling their own identity. Founded in 2020 by two Stanford dropouts during the COVID-19 pandemic, the company operates a lean engineering team and reports that its product is now live on more than 700 campuses across the United States, with rapid expansion under way and systems built to scale to millions of users.
The engineering work spans a range of domains relevant to technically minded marketers: large language models and vector databases applied to novel use cases, machine learning, community-based moderation systems, identity verification and authentication, and full-stack, end-to-end feature development on a social platform. Fizz emphasises rapid iteration and learning directly from users, and describes maintaining intimacy at scale, along with safety, authenticity and inclusion, as core product concerns.
The company values ownership and autonomy above all: engineers ship complete features and actively shape engineering culture rather than working within narrow specialisms. Fizz operates in the social media, consumer technology and higher-education verticals, and describes its mission as redefining social online.
