About Smartnumbers
We are on a mission to stop fraud and improve customer authentication. Fraud is a huge problem affecting millions of people, it costs the UK nearly £7bn and represents 40% of all crime. Too often the solution has been to put in place cumbersome authentication processes that frustrate genuine customers, cause inefficiencies for organisations and fail to prevent fraud. We are changing this by providing organisations with real-time insight into the risk of a caller.
We combine patented machine learning technology with our deep domain knowledge to prevent contact centre fraud. We recognise that we need to work together to fight fraud, and we have fostered strategic partnerships with leading global organisations like Amazon, BT, Genesys and NICE. Together, we protect the UKs largest retail banks, investment banks and emergency services. We also believe in developing our people and building high performing teams, reflected by our Platinum Investors in People accreditation.
