Why we do this

We have spent years turning complex social systems into diagrams. What we saw again and again was the moment a discussion splits in two, and those two become the only things anyone can see. In fact there is a great deal to consider in between. That is what we mean by division.

Purpose

Beyond either/or

Making it possible to keep talking over the same structure, even while positions and views stay different.

What kind of company?

ZUKAI is a visual think tank that structures complex social systems through diagrams, so that people can move a conversation forward while looking at the same structure.

Our page on B Lab ↗

Turning a question that tends to stay vague — what makes a good company — into something measurable is the same work we do: putting complex things into a form anyone can handle. We have shared that view since 2017, and wanted the same standard applied to how we run the company, not only to the work we put out. We were certified in May 2026.

Products you can use

6 in all

The formats, turned into something you can work in straight away.

Bizgram ↗A web tool where anyone can draw the business model of any venture in the same format, using a 3×3 grid and arrows. A gallery of worked examples is free to browse.

Slides ↗Layout, color and type are set in advance, so you get clean slides just by adding the content. No one has to make the design calls alone, and a team's slides stay on-brand.

Kaikei ↗An accounting game: place the transactions as they fall, and the Accounting Map takes shape on screen. You learn how the numbers connect by playing.

Kadai ↗Map the causal links between the issues a region or an organization is facing, then plan solutions and share them with everyone involved.

Purpose Model Studio ↗A web tool for laying out stakeholders and roles around a shared purpose, to build the blueprint of a co-creation project.

ZUKAI Shop ↗An online shop selling the diagrams ZUKAI has built — data, templates, toolkits. Take the diagram itself and use it in your own work.
