Software studio · Web, iOS & Android

Web and mobile software, built to last.

Yax Kuk Mo is an independent studio. We design, build and run apps for the web, iPhone and Android: our own products, and yours.

Our work

We build our own products and run them every day, so we know what it takes to keep software working after launch.

The name

K’inich Yax K’uk’ Mo’ founded the royal dynasty of Copán, in present-day Honduras, in 426 CE. Sixteen rulers followed him over four centuries, and their stelae still stand. His name joins the sun (k’inich), the quetzal (k’uk’) and the macaw (mo’).

We took it as a standard: make things that last.

Yax Kuk Mo LLC was founded in 2026 by Daniel Letona.
