The isee

isee systems is dedicated to making the world better through Systems Thinking. As the market leader in Systems Thinking tools, we have delivered Systems Thinking training, consulting, and software (Stella® and iThink®) for almost 35 years.

Cutting-Edge Software

Our software is designed and developed by Systems Thinking experts with 80+ years of combined experience solving real-world problems and teaching System Dynamics modeling. We both innovate and listen to customer feedback, incorporating user requests into our three to four major — and many more minor — software updates per year. Software updates are free with your maintenance and support contract. We also offer online modeling software that is always up to date and includes a limited free version.

Outstanding Support

Our personal and responsive technical support is only a phone call — or email or chat — away. There is a dedicated team standing behind the software, ready to help you in any way possible. We often go beyond the bounds of technical software support by providing modeling help as well. We also provide extensive online free or low-cost resources for learning both the software and modeling. These include webinars, blog posts, online documentation, and sample models that will get you started.

Effortless Expression

Our software enables you to readily communicate your insights to third parties using, for example, our innovative storytelling feature. You can easily build compelling custom interfaces on top of your models which can then be published to the web (on the isee Exchange), the desktop (Windows and Macintosh), and/or mobile devices (Android and iOS).

Excellent Education

Our software is famously intuitive to use, allowing people to pick it up within hours. This makes it an excellent choice for student modelers, ensuring the successful development of the world’s future Systems Thinkers. We also offer substantial discounts to educators and students to make it easier to adopt into your curriculum.
