The input device for the real world
LITHO Controller

LITHO IS the input device for the real world.

Interact with the world beyond your screen

LITHO’s tracking technology unlocks the potential of real world interactions allowing developers to create more dynamic, intuitive and precise mobile augmented reality applications than previously possible.


LITHO itself is a small finger-worn controller that connects to your smartphone or headset.

The controller has a touch surface on the underside, an array of motion sensors and provides haptic feedback.

Simply by pointing, control your smart devices.

With your phone still in your pocket, you can directly control your lights, thermostat or smart speaker. No touchscreens, no remotes, no control panels.

Our goal is to create a new relationship with technology – one where technology isn’t a barrier to the real world, but a tool to enhance and engage with it.



LITHO was founded by Nat Martin and Charlie Bruce. They met in the IT room at school aged 11, and have been building things together ever since. Before LITHO Nat worked as a research associate at the University of Tokyo, while Charlie previously led the hardware and firmware development of bicycle navigation start-up Beeline.  

The company received seed investment from US based venture capital fund Greycroft, Paul Heydon (an early investor in Unity and Supercell), Chris Albinson (Co-led investments in DocuSign, Pinterest and Turo) and several other angel investors.

Luke Wroblewski, co-founder of Polar (acquired by Google), cofounder of Bagcheck (acquired by Twitter), and author of Mobile First is a key advisor to LITHO on product design and strategy.
