Cognitive neuroscientists and colleagues Brandon Ally and Scott Wylie were watching the 2014 NFL Draft and observed analysts breaking down the prospects with words like great instincts, plays faster than his footspeed, nose for the ball, field vision, etc. What they were missing was a way to measure these skills. 


Together, Brandon and Scott launched S2 Cognition to leverage their backgrounds as athletes and vast experience in studying the brain in order to generate testing that's scientifically proven to measure these unique abilities in athletes. The S2 platform gives athletes and coaches a baseline for how to improve their performance over strength, speed, and conditioning drills.
