Using our experience in internet technology and global finance, we’re making online payments easier to use, safer and more convenient than ever. So, how exactly are we doing this? Unlike existing systems that are closed and proprietary, we use open internet standards and protocols, including the blockchain (allowing us to offer this service for free). We also foster innovative approaches to risk, including our AI risk engine, which runs on cutting edge algorithms that continuously keep your money safe. Circle, the Boston-based internet bank started in 2013. It runs on the blockchain network, the technology that underpins cyber currency Bitcoin, and so payments can be sent instantly to contacts like a text message.
