About

SIRUX

Etymology

The name comes from Thai and its Sanskrit roots.

ศิ (si)

Si (from Sri) · Sanskrit śrī

Radiance, prosperity, fortune. In Thai: head, glory, leading.

รัก (rak)

Rux (Rak) · Sanskrit rāga

Passion, desire, attachment. In Thai: love.

A reminder to not just use our hands, but to work with head and heart: with thought and feeling.

Origin story

This studio began with small client projects for restaurants in the Bay Area. Working in hospitality taught us how much details matter: how design, flow, and atmosphere shape the way people experience a brand.

From there, Sirux grew into working with startups in Asia, helping them launch ideas and connect with their audiences. Along the way, we started building our own software, tools designed to make business easier and creativity more tangible.

Philosophy

“Build what matters.”

We care about craft, clarity, and creating work that people actually feel. Whether it’s a brand, a website, or a product, the goal is always the same: make something that works, and make it with care.
