We build for the trail

Software for trail and ultra runners. First up: KM0, one place for gear, training, and race day.

Discover KM0

We're a small team. We run. We build.
KM0 is the first thing we're shipping: the app we wanted for our own training and races.

What we do

Software for people who run long

We train on trail and race ultras. We got tired of spreadsheets, scattered apps, and PDFs that don't talk to each other. So we're building the tools we wished we had. KM0 is the start: one place for your lists, your plan, and race day.

Trail and ultra first. No generic fitness fluff.
