Creators: The design of IEX and its launch in September 2016 was the result of a collaborative effort of engineers, programmers, designers, mathematicians and trading experts at IEX over the course of years. For example, the co-founders and early employees of IEX, led by CEO Brad Katsuyama, President Ronan Ryan, CTO Rob Park, and COO John Schwall, designed the first iteration of the speed bump, which was included in IEX’s off-exchange marketplace, which operated for over two years before the launch of the exchange. The quantitative strategy team, led by Dan Aisen and Allison Bishop, developed the IEX Signal, and the user experience team, led by Josh Blackburn, designed the IEX API. In the lead-up to the launch of the exchange in September 2016, the entire company – from Head of Product Adrian Facini to market operations and the regulatory and compliance teams – worked together to design, implement, and test every piece of the exchange to make sure it worked seamlessly and complied with all regulatory standards. It truly was a team effort, and the evolution of the exchange will continue to draw on expertise across the company moving forward.
