In the World in You x Org Interview Series, we shine a spotlight on the trailblazing impact organizations and visionary entrepreneurs dedicated to forging a brighter, more sustainable society.

This time, we welcome Tomáš Halász, Co-Founder and CEO of TrollWall AI, a Slovakia-based startup at the forefront of combating online hate.

TrollWall AI is a moderation tool that uses artificial intelligence to automatically detect and hide hate speech and harmful comments on social media. It is increasingly being adopted to protect the accounts of NGOs, politicians, and businesses across Europe. With human-like accuracy in understanding context and the ability to operate across multiple languages and cultures, the system was highly praised and received an award at the 2024 World Summit Award (WSA).

In this event, we’ll hear from Tomáš about the motivations behind developing this system, as well as the challenges related to online discrimination and the state of digital discourse in Slovakia. The conversation will offer valuable insights for anyone interested in using social media for social impact, supporting marginalized voices, or creating safer online spaces.

Don’t miss this unique chance to hear directly from a global entrepreneur. We hope to see you there!

Tomáš Halász, Co-Founder and CEO of TrollWall AI

TrollWall AI

Tomáš Halász is the Co-Founder and CEO of TrollWall AI, a Slovakia-based startup that developed an AI-powered moderation tool with human-level accuracy. TrollWall AI was born out of the urgent need to address the growing wave of hateful comments on social media. As a community manager and activist, Tomáš saw firsthand the harm caused by toxic online behavior and recognized the need for a tool that could effectively filter harmful content.

Today, TrollWall AI protects hundreds of social media profiles across seven countries from reputational risks by automatically detecting and hiding hate speech and harmful comments. The tool is used by a wide range of users—including newspapers, PR agencies, companies like O2, NGOs, the IIHF Ice Hockey Championship, and even national defense institutions. Prominent public figures such as Czech President Petr Pavel and Slovak President Zuzana Čaputová are also among its users.
