A startup called Bolt wants to give e-commerce retailers a better shot at competing with Amazon. Operating in stealth for a year, the payments platform has grown to 100 online merchants who are now in various phases of roll out with its end-to-end solution for managing customer checkout, payment processing, and fraud detection. The company was officially founded in 2014, with an initial focus on using digital currency in online checkout by Ryan Breslow, who had left Stanford to pursue the idea. But after a year of experimenting, Breslow found there were other ways to improve the online payments experience on retailers’ sites. “The checkout experience isn’t great – when you click ‘checkout’ and it goes through the payments step in online shopping, there are actually dozens of different underlying tools that power that,” explains Breslow.
