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.
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.
We design and develop batteryless products powered by NFC energy harvesting — including LogCase, our flagship E-Paper iPhone case that runs entirely on a smartphone tap.
