But Ravelin has exceeded them. The machine learning model is proving to be very accurate. When we added the fraud scoring model to our day-1 ruleset, we saw dramatic improvement. And now it’s fully embedded, we understand our fraud and can react quickly." – Nick Aiken, Director of Fraud and Payments [Read now](https://www.ravelin.com/case-studies/trainline-fraud-case-study) ![](https://storage.googleapis.com/ravelin-website-assets-production/assets/images/clients-page-Glovo-Testimonial-Logo.svg) ### Boosting authentications for Glovo Legitimate customers can complete their shopping journey without any friction, which both decreases churn and makes them more likely to return. "Managing risk and 3DS through Ravelin helps me create a feedback loop between 3DS and risk. 3DS outcome information is fed back into the risk engine." – Boris Montin, Director of Risk & Identity at Glovo [Read now](/case-studies/glovo-ravelin-3ds-case-study) ![](https://storage.googleapis.com/ravelin-website-assets-production/assets/images/River-Island-Testimonial-Logo-updated.svg) ### Automating River Island's fraud strategy "Ravelin has a freshness and passion for fraud that is apparent to me every time we speak. We work in partnership to improve things. This can mean that tough questions need to be asked and answers sought. We never compromise on holding each other to account, but there is a camaraderie and friendship across all levels of both organizations." – Grant Shipway, Global Fraud Manager at River Island [Read now](https://www.ravelin.com/case-studies/river-island-transforms-fraud-strategy-with-automated-decisioning) ![](https://storage.googleapis.com/ravelin-website-assets-production/assets/images/River-Island-case-study-1.png) ![](https://storage.googleapis.com/ravelin-website-assets-production/assets/images/Testimonial-Logo-Kinguin-1.svg) ### How Kinguin transformed its approach to fraud In a matter of two years, Kinguin’s Fraud and Risk Intelligence Team has pivoted from being a weak link in the chain to a crucial function that powers merchant growth on the platform. “What do I love most about working with Ravelin? It’s the service. I have the best account manager I could hope to work with.” – Egemen Ertop, Head of Fraud & Risk Intelligence at Kinguin [Read now](https://www.ravelin.com/case-studies/kinguin-ravelin-case-study) ![](https://storage.googleapis.com/ravelin-website-assets-production/assets/images/Sliding-Logo-paylolly.svg) ### How Ravelin helped Paylolly go-to-market fast “My experience of Ravelin’s 3DS product has been faultless.
