Baku
Personalized biological intelligence from your wearable data.
In Japanese folklore, Baku is the dream spirit — a guardian that protects sleep and transforms what ails you into strength.
Your data, finally interpreted
Baku connects to your wearables and builds a personalized model of your biology — calibrated to your history, not population averages.
