Fizz, the Anonymous Gen Z Social App, Adds a Marketplace for College Students
Teddy Solomon, co-founder of Fizz, recently moved into a new house in Palo Alto and turned to the Stanford community on Fizz to furnish his room. He was thrilled to score a $100 TV from a grad student who was about to move out for the summer. Solomon, who grilled the seller with questions about the marketplace, was impressed by the experience.
When we first met Fizz's Stanford dropout co-founders in 2022, the anonymous social media platform was only available on a dozen college campuses. Today, the app operates on 240 college campuses and 60 high schools, with a team of 30 full-time staff and 4,000 volunteer moderators across schools. Fizz has raised $41.5 million across multiple funding rounds, powering its growing presence in campus culture.
Even in those early conversations, Solomon mentioned Fizz's plans to open a marketplace, where students can buy and sell items like clothes, textbooks, bikes, and more. College students often make these kinds of transactions since they're moving between dorms every year, and maybe they want some money back for their lightly used calculus textbook.
Solomon believes that the market for a local, Gen Z-focused buying and selling platform is wide open. He thinks that the stigma around selling on platforms like Craigslist or Facebook Marketplace is a major turn-off for Gen Z users.
The marketplace feature rolled out across Fizz's hundreds of campuses between March and May of this year, in preparation for the predictable end-of-semester rush to sell. Solomon said Fizz has had 50,000 listings posted on the platform, with 150,000 DMs sent around items. The most popular category is women's clothing, which amounts to about 75% of listings.
However, Facebook Marketplace won't be an easy competitor to beat. Some young Facebook users say they only go on the platform for the marketplace. Even though fewer Gen Z users are on Facebook, Meta is working on recapturing that generation's attention.
Payments are not yet integrated in Fizz, so users are responsible for navigating their sales. Solomon said Fizz may build out a payment structure to make the marketplace more user-friendly, but he isn't thinking about monetization yet. While Fizz may be rich in venture funding, this classic Silicon Valley move of prioritizing growth over profit isn't as feasible in the next generation of social media.
Fizz is fully anonymous, even on the marketplace. But to get onto a school's Fizz community in the first place, you need to verify a school email account. So, while there's always a risk in meeting up with a stranger – even if they go to your school – users seem less hesitant about buying from their classmates.
"One of the statistics we really love that we were looking over the other day is that on average, every seller has two people reach out to them before they sell," Solomon said. "If you know they're in the dorm next door to you, you don't have any reason to figure out if they're legitimate or not. It's pretty easy."
But as with the anonymous social platforms that have come before it, Fizz has struggled to maintain a safe environment on all of its campuses. In one high-profile case, a Fizz community wreaked havoc on a high school, as students hid behind anonymity to shame and torment other students and faculty.
"We've had two communities that we've voluntarily shut down just because of feedback from parents and administrators," Solomon said. Since then, Fizz has refocused its commitment on content moderation. In the past, Fizz paid part-time student moderators to monitor their communities. Now, the company has dedicated staff that work on trust and safety, and it's using technology from OpenAI to make its automated moderation more robust.
These efforts may not be enough to mitigate concerns, though. On anonymous apps, school administrators have seen terrible scenarios play out before – remember YikYak? The president of the University of North Carolina, which has sixteen campuses, announced plans to ban anonymous apps like Fizz, Whisper, and Sidechat from the school. So, those students won't be able to buy pre-owned textbooks on Fizz's marketplace.
"We're very aware that as an anonymous, Gen Z platform, moderation has to be our core," said Rakesh Mathur, CEO of Fizz.
We accessed one university's Fizz community. Students posted about sex and drugs – these topics are allowed on Fizz – but were not bullying each other or sparking harmful dialogue. But this is just one community out of hundreds. While Fizz's momentum in growing its content moderation team is promising, even the largest, most resourced social platforms still struggle with toxicity.
Fizz's argument in favor of the anonymous nature of the platform is that it encourages students to open up about how they're really feeling – when a student sees posts about how other people might be stressing over an exam or struggling socially, they'll know they aren't alone in those experiences. On the brighter side, users might find some great campus-specific memes. Or, now that there's a marketplace, they might be able to score a great deal on a TV.
