Fatigue intelligence, built with science and purpose.

I've worked in the sleep industry for over twelve years, though in a very different corner of it. About nine years ago, I partnered with the National Institute for Health Research and Imperial College London on a study exploring what our previous product could do for people working shifts. That project changed the direction of everything that followed.

I spent weeks interviewing shift workers — nurses, drivers, warehouse staff, engineers — and I was struck by how quietly devastating the impact was. The fatigue wasn't dramatic. It was erosive. It wore down their health, their energy, their patience with the people they loved. Relationships suffered. Bodies broke down. And almost nobody outside their world seemed to notice or care.

What stayed with me was how avoidable so much of it was. Not all of it — shift work will always carry risk — but a remarkable amount of the damage came from patterns that could have been caught and changed. A rest period moved by two hours. A rotation reversed. A night sequence shortened by one shift. Small adjustments that nobody was making because nobody could see the problem clearly enough to act.

Those conversations never left me. When I finished my previous company, I went back to the academics I'd worked with over the years and asked a simple question: what would it take to make the fatigue risk in a roster visible — genuinely visible — to the people who have the power to change it?

The answer became RosterWise.
