Prototype
Tidewell Brain
One agentic brain, two modes: Solo on the robot, Crew across the site.
Singapore · Physical AI
Physical AI for the places that never close.
Robots for ports and logistics, for healthcare, and for the cleaning both depend on. Designed and built in Singapore.
- Brain
- Models post-trained on our own deployment data.
- Body
- Commodity actuators, our own hands, touch and firmware.
- Flag
- A trusted jurisdiction between two supply chains.

Products
Products
Five products, one brain. Tidewell Brain runs Solo on a robot and as a Crew across the site; wheels for flat and heavy, legs for decks, stairs, curbs and interiors; a restroom cleaner for hospitals; and a kit that brings the robots you already own under the same brain.
Prototype
Tidewell W1
Wheeled mobile manipulator for flat, busy floors.
Prototype
Tidewell B1
Biped for decks, stairs, curbs and interiors.
In development
Tidewell C1
Restroom cleaning robot for hospitals, on the W1 platform.
Prototype
Tidewell Crew
The connected mode of Tidewell Brain, sold on its own for mixed fleets and the people beside them.
Prototype
Tidewell Brain Kit
Tidewell Brain on a robot you already own, with the vendor's telemetry removed.
Thesis
Where value sits
01
The brain is where the unsolved problem and the capital sit. We post-train open base models on our own deployment data.
02
The body is a commodity where China is strong and a moat where it is weak. We buy actuators and build hands, touch, firmware and comms.
03
The flag decides who can buy. Singapore is a trusted jurisdiction between the two supply chains.

Where we work
Ports and Logistics
Tuas is already automated on the flat. The work that is left is on the vessel, in the container and on the stairs.
Healthcare
Non-clinical logistics first, through the one gate every public hospital uses.
Cleaning
The restroom is the hardest room in facilities work, and the one room a camera cannot enter.

Restroom cleaning robots, September 2026
The restroom cleaning category read vendor by vendor: what the incumbent machine actually does, what a Singapore restroom cleaner costs by statute, the only published rental prices in the market, why a camera is the binding constraint in this one room, and what we concluded before starting C1.
