We chat with folks from Clearpool, a financial services firm that provides a wide variety of technology tools and routing infrastructure to sell-side broker-dealers to help them seek best execution for their institutional clients. We cover the technical aspects of how trading works, the speed at which it happens, and some of the technologies being deployed. These technologies are cutting edge in terms of speed and reaction time, which may pave the way for speed in other industries. The Clearpool team also gave us insight into being a startup in a competitive space.
