About Us
Third Pillar of Health began in 2011, emerging from a business already five years into its mission. As of April 2026, we are proud to mark 20 years of dedicated work in the field of fatigue, sleep, and human performance.
Our Managing Director, Marcus de Guingand, has been at the helm throughout this journey. After six years in London's banking sector, Marcus shifted his focus to tackling one of the most overlooked challenges in the workplace: fatigue. Today, he leads a multidisciplinary team of experts spanning sleep science, circadian biology, design, development, mathematics, statistics, programming, finance, light therapy and more. This breadth of expertise allows us to approach fatigue from every angle – scientifically, practically and strategically.
Our great passion is tackling fatigue at work. We help tackle fatigue in many ways. It is often about imparting knowledge and awareness through our Sleep Health Self-Assessment, education, training or with our alertness and cognition test. These are proven solutions with track records of positive outcomes.
Our passion is simple: helping organisations reduce fatigue and improve safety, wellbeing and performance. For two decades, we've delivered proven solutions – all with a strong track record of measurable, positive outcomes.
Today, our purpose-built digital platform, Fatigue-Risk.com, brings everything together. It makes fatigue risk visible, measurable and manageable, going far beyond compliance to deliver genuine, data-driven improvements at both individual and organisational level.
We are uniquely positioned to help you understand the extent, impact and causes of tiredness and fatigue within your workforce and to guide you toward effective, targeted action.
If you're ready to tackle fatigue in your organisation, we're ready to partner with you.
