About Tempest

Why I'm building Tempest

I’m an interface engineer in offshore wind. I spend my days making complex systems talk to each other, usually from a desk. I used to be reasonably fit, but once the kids came along my gym and training routine quietly disappeared.

What got me moving again was a smartwatch. Counting steps, recording runs, seeing the numbers build: it gave me a reason to get out of the door. But the longer I wore it, the more I noticed that all that tracking sits in separate boxes. A sleep score here, a heart rate graph there, a training status somewhere else.

Recently that gap became personal. For weeks I felt flat, and my body ached for days after workouts. Eventually my watch started showing low HRV warnings in the mornings. When I looked properly, my HRV had been drifting down for a whole month. The data was there all along, and so were the extra workouts I kept logging, but nothing joined the dots or suggested I ease off. Seeing it in black and white is what made me rest, and book a check-up with my GP. Without it I’d have kept pushing on and run myself down further.

That’s the companion I wanted: something that brings your data together, learns how you work from what it tracks and what you tell it, and speaks up early, then points you to real people when that’s the right call.

Now in my forties, I’m interested in health and longevity in a way I wasn’t before. In time, Tempest will bring together watch data, blood tests, coaches and doctors. For now, I’m building it from Northumberland, alongside my day job, and in public.
