About Sivvexa

A Software Partner That Thinks Like a Business Owner.

Sivvexa was built on the belief that great software engineering and deep business understanding should not be separated. They belong together.

Our Story

Sivvexa was founded by Werayoot Kunphai (นายวีรยุทธ กันภัย), a full-stack software engineer based in Thailand with years of hands-on experience in software delivery.

After working as an engineer on teams of varying sizes, one pattern became clear: the gap between what a business needs and what software teams deliver is almost never a technical problem. It is a communication and alignment problem.

Sivvexa exists to close that gap. By combining senior engineering execution with a genuine understanding of how businesses operate, we are able to scope accurately, build the right thing, and deliver systems that actually get adopted and used.

The name Sivvexa reflects a commitment to precision and craftsmanship — qualities that matter when the software you are building will run critical parts of your business.
