  1. Ravelin How Ravelin is leveraging data to combat fraud rather

    than managing infrastructure. Leonard Austin | 29.03.2017 ravelin.com
  2. Meet the exec team Martin Sweeney CEO Leonard Austin CTO

    Nick Lally COO Mairtin O’Riada CIO Gerry Carr CMO Mairtin is as obsessive about catching fraudsters as he is about drinking tea. Before Ravelin, he had a storied career in international intelligence which gave him the perfect insight into the criminal mind. Previously Head of Fraud at Hailo, he’s now channeling all that experience into the perfect fraud product. Leonard has been designing, developing and deploying online technologies for over a decade. He is passionate about the power of agile teams, iterative development, continuous integration, automated testing and empowered engineers. He can often be found in the far corners of the earth. Martin was Founding Engineer at Hailo the taxi app, building the systems and team there over four years into a global business. He is a Physicist by training, but left behind an academic calling for the glamour of fraud detection and software. Martin is a father, husband and sporadic fisherman. Nick loves creating teams and processes in fast-growing organisations. Before Ravelin, he held Finance Director roles at Hailo and Canonical, the company behind Ubuntu, the OS that dominates cloud computing. An accountant at heart, he hates seeing any company lose money to pesky fraudsters. Gerry was the original marketing hire at Ubuntu and over five years there launched its cloud products, seeing it become the most used cloud OS in the world. Now juggles breaking phones with making people in the fraud prevention business aware of what Ravelin can do. ravelin.com

  11. Requirements Better than 3D Secure Fraud Detection Fast We sit

    within the checkout flow <300ms Process & Store Big Data All historic data from all clients. All real-time data from all clients. Global Markets Clients operate all over the world. Fraud is different from country to country. Highly Available Clients rely on Ravelin to decide whether to accept an order Secure We store/analysis bank cards, location data and PII (e.g. address, email, phone, transaction history etc) data ravelin.com
  12. Coverage

  13. ravelin.com Ravelin’s Graph DB is1000x the speed of traditional graph

    database solutions. Can be integrated into real-time scoring. Ravelin maps every user, card number, phone number, device, email, IP Address etc Ravelin Network
  14. ravelin.com Ravelin’s rules engine allows configure custom rules based on

    client’s experience of fraud. Set the boundaries acceptable behaviour. We track purchasing behaviour prior to the transaction so that each decision is made with as much information as possible. Rules & Fingerprints
  15. No other approach provides the accuracy that our customers demand

    at a speed and scale that fits in with how their businesses operate. Our data science teams deploy models across industries and fine tune them for clients. These models learn based on the fraud that our clients experience, taking out much of the analysis work that goes with traditional rules based systems. This leads to higher accuracy - less fraud, and fewer genuine customers being turned away. ravelin.com Machine Learning
