This tool will generate a convertible note term sheet based on your responses to an online questionnaire. It also has an educational component, with basic tutorials and annotations. This term sheet generator is a modified version of a tool that we use internally, which comprises one part of a suite of document automation tools that we use to generate start-up and venture financing-related documents.
