Who we are

Fizz is a private and authenticated platform designed to revolutionize the social fabric of communities, starting with colleges. After verifying a university email address, students use Fizz to post questions, memes, polls, and chat directly with other verified students, all while maintaining full control of their identity and privacy. Fizz communities are safe, authentic, and inclusive, made possible through community-based moderation.

Launched by two Stanford dropouts, Fizz is currently expanding into colleges all across the US. In a time when social media is plagued by curated highlight reels and lack of authenticity, Fizz is on a mission to redefine the definition of a true social network.

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. In July 2023, we raised a 25M Series B and have established ourselves as the dominant community platform at 80+ colleges.

Where we’re going

Our near term goal is to expand to all US universities by the end of the 2023-2024 academic school year. To get there, we give engineers at Fizz a lot of autonomy and ownership of our product. Some of the things you can expect to work on include:

- Building and maintaining scalable human in the loop AI community moderation systems

- Utilizing NLP systems to automatically categorize and target content to users

- Conducting analysis on larger amounts of user-generated content and using data to drive product decisions
