ABOUT
A tree Z.
We help turn business ideas into AI services. Together, we choose where to start, build around your workflows, and keep improving after launch as an extension of your team.
THE NAME
A tree connecting A to Z
Experience takes root in each project and grows into new possibilities. Our name reflects how we work.
Branches
The next industry
The designs and experience we build become a starting point for the next client’s business.
Trunk
Shared building blocks
Project experience becomes reusable components: conversation engines, human handoff designs, and safeguards.
Roots
Industry experience
We start in the field across many industries—commerce, fandom, media, legal, and the public sector.
PRINCIPLES
How we work
- 01
Start from the work
Start with the work you want to change. Define success in terms of what happens in that workflow.
- 02
Stay involved after launch
The same team monitors quality and cost and keeps improving the service after launch.
- 03
AI for meaning, rules for format
AI reads meaning and context; rules check the format of numbers and dates and the required fields.
- 04
Facts, stated precisely
We don't claim results we haven't measured. We separate what we can do from what still needs validating.
- 05
Data belongs to the client
What we carry to the next engagement is patterns and operating experience—never client data.
AI-NATIVE TEAM
People set the direction.
AI agents help build.
We started by changing our own development work with AI. People set the direction; AI agents contribute to design, implementation, and review.
