1/ The brain is the most complex system in the known universe, yet you’ve likely never measured yours. Why? Because until now, the technology to do so easily and affordably didn’t exist. Kernel Flow is the world’s first high-fidelity brain measurement system designed for mass…

2/ BrainAge quantifies your brain’s function in 7 minutes. Kernel Flow fuses hemodynamic and EEG signals for research-grade insights. Top institutions use it for Alzheimer’s, depression, even psychedelics.

3/ I've personally worn Kernel Flow to measure the effects of ketamine, track changes from sleep, and evaluate a range of other therapies.

A more robust panel of brain measurements are coming out this summer.

Details:
+ available in LA (Culver City)
+ $50
+ schedule: kernel dot com / brainage
+ rolling out in the U.S. and globally

Advanced measurements coming summer 2025:
1. complex attention
2. executive function
3. learning and memory
4. language
5. perceptual-motor control

0/ I founded Kernel in 2016 with $54M of my own money. My goal was to crack the code of human cognition and pair the brain with AI. We built Kernel Flow, a wearable that maps your brain’s activity like a fitness tracker.

We’ve already seen data showing that alcohol makes the…
