Stripe launches Radar to tackle e-commerce fraud with machine learning

Stripe, the startup that lets websites and mobile apps implement payment services through its API and a few lines of code, is today adding in another new feature as it continues to build out its platform with more tools. It is now going to help prevent fraud on Stripe transactions, through a new service called Radar. Radar is being rolled out globally as part of Stripe's primary payments service, meaning companies that use Stripe's API for payments do not need to pay extra or do anything in particular to turn it on. That may change down the line if and when Stripe -- which has now raised around $300 million and is valued at around $5 billion -- begins to add in more features and decides to monetise the service separately. "This is an area of active development and there is a long list of things we want to do," said John Collison, Stripe's co-founder and president, in an interview. "We haven't ruled out [launching it as a separate service] but want to see how people use it and what works and what doesn't first."
