About Thinking Cap: Thinking Cap was founded in the spring of 2001. In 2003, Thinking Cap launched the first versions of Thinking Cap® Author and Thinking Cap LMS. Without a customer, we made the investment to create the first XML-based eLearning system. This was done for one reason - it was needed. With over 70 commercial and open source Authoring Tools and LMS products on the market not one used XML to facilitate reusability and single sourcing. Thinking Cap was created to fill that gap.
