About Astah & Change Vision, Inc.

Make software design
more productive, rich and fun.


Innovation is rarely the result of rigid thinking, but most engineering software follows a mechanical process. It requires strict, formal, and mechanical thought. It gets the mechanical side right … but it isn’t user-friendly, and it doesn’t provide an environment that allows engineers to improvise and interact with coworkers.

At ChangeVision, we thrive on inspiration. We saw programmers getting bogged down in endless lines of code with no chance to be creative,
and we wanted to change the way that individuals and groups work when developing software. We wanted to provide a common forum that would make software design more productive, rich and fun. We wanted to build something more intuitive – something that would engage our imagination and our urge to create as a team.

The result is Astah. And that is why simplicity, quality, and community remain our three greatest priorities.

That is why we provide a product that:

  • Works intuitively with Windows, Mac, and Linux to provide seamless transition between diagrams, tables and platforms.
  • Delivers a uniquely dynamic and social development experience at a low price.
  • Benefits from ten years of user-driven tailoring and expansion to bring your team and your project together.

CTO Kenji Hiranabe’s Mission

I started this company in 2006 to develop and market Astah, a UML editor integrated with Mind Mapping features. My background is in software engineering, something I’ve been doing for more 20 years. For about half of that time I worked on practical applications for object-oriented technologies, the other half for Agile approaches in real world software development. I believe in the power of modeling and diagramming to inspire creativity, to help teams communicate, and to build better software.
