Building since 2023

We build the tools
that move businesses forward.

GJAON Technologies is a product and services studio. We ship our own software — like SellSquare and Chatalog — and we build for clients who want the same level of care: web and mobile apps, UI/UX, marketing, video, brand, and data.

What clients say

Trusted by founders and operators.

The best testimonial is the next project. Most of our work comes from clients who came back.
