WHOOP was founded in 2012 by Will Ahmed, then a Harvard student athlete, who was determined to enhance his training and recovery. After reviewing over 500 medical papers, Ahmed discovered that continuous monitoring of metrics like heart rate and variability could significantly boost performance and wellbeing. This insight led to the creation of WHOOP, a groundbreaking wearable that provides unparalleled visibility into how sleep, strain, and recovery impact overall health and performance.
From its beginnings with elite athletes like LeBron James and Michael Phelps, WHOOP has revolutionised the understanding of human physiology. The company's mission is to unlock human performance by offering deep insights into the body’s functions and helping users achieve their highest potential physically, mentally, and emotionally. WHOOP’s relentless pursuit of understanding and optimising human performance continues to drive its innovation and impact.
