ZUKAI's products

Bizgram
A web tool for drawing the business model of any venture in the same format, using a 3×3 grid and arrows. A gallery of 162 examples is also available for free.

Slides
A tool that fixes layout, colors, and fonts up front so you just fill in the content to make polished slides. You won't get lost working solo, and your brand won't drift across a team.

Kaikei
An accounting puzzle game where placing falling transactions grows an “accounting map” on screen. Not memorization—the flow of a company's money settles in as you play.

Kadai
Structure the cause-and-effect relationships between the issues a region or organization faces on a map, and go from planning solutions to tracking progress in one tool.

Purpose Model Studio
A web tool for building the blueprint of a co-creation project (a purpose model) on the spot—placing stakeholders and roles around a shared purpose. Now mobile-friendly.

ZUKAI Shop
An online shop selling the diagrams ZUKAI has developed—data, templates, toolkits, and more. Get the diagrams themselves and use them in your own work.
