Measure Brain Function. Improve It.
BrainYears™. Functional brain age. 643 biomarkers. Built to measure and train. Developed in collaboration with the Buck Institute for Research on Aging.
Longevity's Blind Spot
Comprehensive longevity protocols cover the body thoroughly, blood panels running past a hundred biomarkers, DEXA scans, full-body MRI, sleep and HRV tracked over time. The brain is the exception. It is the one organ system most protocols don't directly measure, despite being the single strongest predictor of how long a person will live.
2.82x
Higher mortality risk for people with the most aged brains, over 15 years.*
13.5x
Higher likelihood of an Alzheimer's diagnosis for people with the most aged brains, independent of genetics.*
*Stanford University researchers, Nature Medicine (2025), 44,498 UK Biobank participants.
The Case for a Brain Age Clock
For decades, medicine has treated the diseases of aging as if they were separate problems. Treat the cancer, then the heart attack arrives. Manage the diabetes, then Alzheimer's follows. Buck Institute President and CEO Eric Verdin calls this "whack-a-mole medicine," and argues the better approach is to target the aging process itself, before diseases appear. Many innovators and researchers are trying to model the aging process, whether across the body or one organ specifically. We've modeled it for the brain, because a younger brain is what keeps you sharp, keeps you relevant, and keeps you connected to who you are.
