A check-engine light for human capacity.
HOLD learns your baseline from the phone you already carry, and shows the warning light early: when your capacity starts to drop, while there is still time to act.
Wearables measure the body, heart, sleep and strain. HOLD measures whether you are still functioning: whether your ability to show up for your life is changing over weeks, against your own baseline, not a population.
A measure of function, not a diagnosis. We test it properly and show the results before we make any claims.
Twenty years turning complex industrial systems into software that predicts failure, from oil, gas and heavy industry to modular construction. Now applying the same systems thinking to human capacity: seeing overload before the breakdown is visible.
PhD applied mathematician. Fifteen-plus years building AI and predictive models for complex industrial systems, turning noisy real-world signals into decisions you can act on.
