Freiburg-based TrustTech startup expands multilingual content moderation platform to 89 languages
The regulatory landscape for online content moderation across Europe is shifting rapidly, with the EU Digital Services Act now mandating that platforms and organisations implement protective measures against harmful content. For the growing number of public figures, sports clubs, and media organisations facing a surge in online abuse, the compliance requirement has created an urgent demand for technology that can identify threats in real time — across languages, dialects, and the ever-evolving lexicon of coded hate speech.
Freiburg-based Penemue has raised more than €1.7 million to scale its artificial intelligence platform for detecting and countering online hate speech, digital violence, and disinformation. The round attracted a diverse investor base including TION Health, Beyond Tomorrow, 4seedimpact, zigzag, Berlin Angel Fund, CGS Consulting and Beteiligungs GmbH, RLM Beteiligungs GmbH, and ILG Group, alongside prominent business angels from encourageventures e.V., Black Forest Business Angels, and Business Angels Mitteldeutschland.
Beyond keyword filters: understanding context at scale
What distinguishes Penemue from conventional content moderation tools is the depth of its linguistic analysis. Rather than relying on basic keyword matching, the platform analyses complex linguistic cues to identify harmful content across 89 languages in real time. The system recognises coded language, slang, regional dialects, and even emoji-based communication patterns, continuously updating its models to reflect emerging terms, cultural shifts, and new forms of digital abuse.
The platform functions as a live monitoring layer for social media comments and direct messages, enabling organisations to hide or delete harmful content with a single click — or escalate cases directly to law enforcement through integrated legal complaint filing.
“It is not just the people affected who are victims, but everyone who reads along,” said Sara Egetemeyr, co-founder and managing director of Penemue. The company was founded alongside Jonas Navid Mehrabanian Al-Nemri and Marlon Lückert, with a mission to make digital spaces safer through technology rather than manual moderation alone.
Bundesliga clubs and federal politicians among early adopters
Penemue has already built a notable client base across Germany and Europe. Bundesliga clubs in both the first and second divisions use the platform to monitor fan interactions and protect players from online abuse. Federal-level politicians, media houses, artists, and influencers also rely on the service, as do public prosecutors and police authorities investigating criminal online communication.
The company’s effectiveness has been independently validated through an impact evaluation conducted by the University of Mannheim, which documented measurable positive effects in reducing digital violence — providing third-party academic credibility that strengthens Penemue’s positioning in a market where claims of AI effectiveness are often difficult to verify.
European regulatory tailwind drives demand
The fresh capital will fund further AI development, new European and international partnerships, and deeper cooperation with public institutions. Penemue’s timing aligns with a regulatory environment that is increasingly favourable to content moderation technology providers. The EU Digital Services Act creates compliance-driven demand across the bloc, while individual member states are introducing their own frameworks for combating online hate speech.
The German startup has already earned recognition as AI Champion of Baden-Württemberg and is a member of Deutsche Telekom’s TechBoost programme. Its partnership with the #NoHateSpeech initiative further anchors it within the broader European movement to address digital abuse systematically rather than reactively.
For Penemue, the challenge ahead lies in scaling a linguistically complex product across new markets while maintaining the detection accuracy that has earned it the trust of some of Germany’s most prominent institutions.
