Zato did not optimise compliance. Zato rebuilt it.

Why Zato?

The name Zato is inspired by Zatoichi, the legendary blind swordsman from Japanese folklore, who moved with unmatched skill, intuition, and grace.

Like Zatoichi, our platform operates with unseen intelligence, cutting through complexity to deliver clean, accurate outcomes with remarkable efficiency.

Native Agentic Engine

Zato is not a bolt-on AI tool, it is AI from the ground up. Powered by Ziffy - our proprietary agent swarm intelligence - Zato coordinates highly specialised AI agents across every stage of your accounting firm's compliance job. One platform, built to think, not just process.

We mean business

Zato is founded by accounting experts who founded and run one of the world's largest accounting solutions group. Our team knows how compliance works in practice and takes our experience from 20 years of operating in the space and completing over 1 million ledgers to ensure Zato is everything you need, and more.
