About · Chronic Trace
Concussion's missing objective biomarker.
We close that gap. An objective concussion and TBI measure, from a single capture on a device the patient already owns.
Why this existsNot built from the
Not built from the
outside.
Concussions since elementary-school football and middle-school lacrosse. Twenty-plus times in my career I took a hit, felt my brain shake and my vision vibrate, and kept playing anyway.
I know the loopholes because I used them.
I faked impact tests. I gamed the balance and Sway screens. So did people I played with. Not because anyone was negligent, but because the system asks an athlete who loves the game to self-report the one thing that takes them out of it. That is a structural problem, not an athletic-trainer problem.
I live with the result. Daily headaches, a history of mild and moderate TBIs. I understand this market from the inside.
Spring 2026 I took another one. I stepped away from the game I love, for good, and went all in on Chronic Trace. This is no longer something I do on the side. It is the whole thing.
We need something cheap, usable by anyone, available right there on the sideline, and hard to fake. That is Chronic Trace. Let us make a difference.
