Wizz App, the social discovery platform built for Gen Z, today revealed the results of its first full year operating with AppHarbr’s independent ad security technology – a milestone that positions the company as one of the most rigorous enforcers of advertising standards among social platforms targeting young audiences.
Over the past twelve months, Wizz App has analyzed more than 4 billion ads across its entire advertising stack, blocking roughly 0.17% as potentially unsafe before they ever reached users. The figures represent continuous, independent ad verification covering 100% of ad content delivered to its 3 million monthly active users ages 18–24.
Closing the Industry’s Enforcement Gap
Most platforms rely on ad networks to self-regulate, an approach that creates a structural blind spot. Demand sources vary widely in their standards, and without an independent verification layer, policy-violating ads can reach users even on platforms with otherwise strict internal guidelines.
Wizz App identified this gap early. In 2024, the company implemented AppHarbr as an always-on enforcement layer across all demand sources simultaneously, evaluating every ad in real time against Wizz’s community standards before delivery. The categories flagged and blocked include malvertising, gambling promotions, sexual content, alcohol, drug-related material, and hate speech, all strictly prohibited under Wizz App’s advertising policies.
“Protecting the community extends to every point of platform and user interaction, including advertising. AppHarbr gives our team the operational visibility to enforce our advertising standards consistently and at scale. With over 4 billion ads analyzed, we know exactly what’s reaching our users and why, and we block everything that doesn’t belong,” said Alexandra Ryabova, Head of Operations at Wizz App.
Why It Matters for Advertisers
For brands and demand partners, independent verification isn’t just a safety story, it’s a quality signal. Knowing that every ad impression on Wizz App has been screened against a consistent, platform-level standard means advertisers can reach a highly engaged Gen Z audience with confidence that their brand appears alongside vetted, policy-compliant content.
“Young users are particularly vulnerable to deceptive, manipulative, and dangerous ad scams,” said Amnon Siev, CEO of AppHarbr. “One year in, the results speak for themselves: this is what meaningful, scalable ad integrity looks like in practice.”
Part of a Broader Safety Infrastructure
The AppHarbr program is one layer within Wizz App’s wider safety ecosystem, which includes proactive content moderation across 70 content classifications, age verification powered by Yoti, CSAM detection via Cinder and Thorn, and membership in the Tech Coalition, one of only three European platforms in the global child safety alliance.
As Wizz App continues to grow, this milestone reinforces a clear operating principle: that community safety and a trusted advertising environment are not competing priorities, but inseparable ones.
