anibis.ch is part of the Ringier Group and one of Switzerland’s leading classifieds marketplaces. Since 2004, the platform has offered a free, trusted space for users to buy and sell items. With over 11 million monthly visitors and 1 million active listings across three languages, anibis.ch has built its reputation on delivering a smooth, safe experience. Their commitment to user trust is clear, with a strict promise that no ad remains online for more than 30 days.
“Besedo offered an easy solution exactly targeting our needs. We couldn’t have been able to develop a better solution.”
Jelena Moncilli, Fraud Specialist
The challenge
As listing volumes grew, so did the challenges. The in-house moderation team could only review 10% of listings, focusing mainly on high-risk categories. Fraudsters quickly spotted the loopholes, posting scams in less-monitored areas like the “baby” category, which was suddenly flooded with shady loan offers.
With budgets tight and resources stretched, anibis.ch needed a smarter way to scale moderation while protecting users and maintaining trust. That’s when they turned to Besedo.
“When our workload increased it forced us to focus on high-risk categories only. Fraudsters soon found out they could bypass our security using other categories which were not or less controlled by us,” said Jelena Moncilli, Fraud Specialist at Anibis.
The solution
The partnership with Besedo began with automated filters through Implio. These were carefully customized to fit anibis.ch’s unique needs and quickly covered 80% of listings. Over the following year, this process also created a labeled dataset, which was then used to train AI models tailored for anibis.ch.
Within two months of training and just one week of integration, anibis.ch had reached 94% automation.
Timeline at a glance:
- 0% automation (2016) — manual reviews covered only 10% of listings.
- 80% automation — Implio filters set up and optimized.
- 94% automation (2018) — AI models trained and integrated.
The results
With filters and AI working together, anibis.ch now automatically moderates 94% of listings with an impressive 99.8% accuracy and 85% recall.
The benefits were immediate:
- 100% of listings moderated before going live, compared to only 10% before
- 85% of fraudulent listings blocked upfront, up from just 15%
- 60% fewer user reports thanks to higher quality and safer listings
“It cost us the same as before, but quality is way better and we are able to check 100% of the listings, which was not the case before,” said Jelena Moncilli.
Benefits & ROI
By combining AI and filters, anibis.ch not only scaled moderation but also gained deeper insights into their content. Every decision is now tracked, giving the team better visibility and allowing them to coach their human moderators more effectively.
The impact on trust and user experience has been significant, all without increasing operational costs.
A unique partnership
Over time, anibis.ch has come to value three key aspects of working with Besedo:
- Experience & Expertise — Besedo reviews more than 570 million pieces of content annually, building the knowledge base needed to stop scams and fraud.
- Support — Filter specialists help fine-tune rules and adapt them when needed, keeping automation levels high.
- Adaptability — No two platforms are alike. Besedo tailored the solution to match anibis.ch’s specific priorities, even approving trusted users’ content instantly.
“Documentation provided by Besedo was clear and easy to understand. Their team is always available for questions, even if we did not have to use this service often,” said Jelena Moncilli.
“We are getting even better data and insights from the moderation process than before outsourcing. Because we’re now able to track every decision,” said Jelena Moncilli.
