Bolted · Design and engineering, since 2014

Intelligence is getting cheap. Judgment is not.

262,144 points, each one an answer a machine could give.

One light picks the one worth sending.

How we work

Someone has to stand behind what ships.

AI does the routine work. One of us reviews every change and tests it on a real device.

Built on proof

Designed to the millimetre. Proven on the device.

Every app is tested on the hardware it ships to, with a written account of why it works.

What we do

We design and build apps that have to work.
