About the Company from the website: 
Their mission is to give every athlete access to a personalized hydration strategy so that they have the best chance of achieving their goals. They formally launched Precision Hydration in 2011 after many years working with elite athletes and technology partners to develop a simple and effective way to help athletes understand and manage their personal hydration needs. Founder (Andy Blow) has a degree in Sport and Exercise Science and was a regular podium finisher in elite short course triathlon racing in his younger days. Initially, he had very poor results when racing in the heat and at longer Ironman distances. He suffered badly from cramping and had other hydration related issues. This was despite following the widely accepted hydration advice available at the time. After years of trial and error he eventually figured out how to effectively manage his individual sodium and fluid intake to maintain his performance and was helped significantly in that process by Dr Raj Jutley, a highly respected heart surgeon who introduced him to the concept of sweat testing and the huge variance in sweat and sodium losses that can occur across athletes. It was through his own search for an effective solution that, with Dr Jutley’s input, the Precision Hydration concept was born. They built up a wealth of data on how athletes sweat and were able to build an algorithm-based questionnaire to deliver personalized hydration advice even if an athlete couldn't make it to one of their test centers.
