Solution Description

Problem description

In mid-2024, Close Brothers encountered a sophisticated fraud. It looked like a dream deal: financing a £135,000 luxury car with a £50,000 deposit. Four months later, the payments stopped. The £50,000 was completely fake. They ended up losing a substantial amount of money. Their manual document review process was taking loads of time and creating workflow bottlenecks but, in the end, it was also ineffective.

Solution

Close Brothers Motor Finance embarked on a trial of Resistant AI’s Document Forensics, which immediately spotted 18 additional cases of fraud. Resistant’s automated document fraud check takes only 12 seconds, replacing the previous 15-minute manual fraud assessment process. Ten months after implementation, Close Brothers estimates that they have prevented £800,000 worth of fraud. The dramatic transformation and success in motor finance has driven expansion plans across Close Brothers’ wider business portfolio, including premium finance, savings, invoice finance and asset finance divisions.
