ABOUT BRACHISTALOG
We build the shortest path from idea to invention.
BrachistaLog designs batteryless, ultra-low-power devices powered by a single tap. We turn experimental ideas into shippable products, fast.
OUR NAME
The fastest path is a curve.
Brachistochrone: the curve of fastest descent between two points. We took that idea and made it our mission: the most direct path from invention to the customer's hands. No detours, no compromise.
