Twelve tools, one per class from class 3 to class 14. Each class adds a primary tool (the thing you make) and an instrument (the thing that tells you whether it is working). Every one is a page or a spreadsheet, kept in your Venture Book, and all twelve become the final pitch and the case study behind it.
The primary tools are the things you make: the canvas, the research plan, the prototype, the brief, the deck. The instruments answer the question every primary tool leaves open, which is how do you know: the assumptions map says what you are betting on, the usability test says whether anyone can use it, the unit economics and the funnel say whether it pays, the metrics tree says how you would tell.
Each one is a page or a spreadsheet. Each one goes in the Venture Book chapter named on its page. The business case at class 8 pulls the first six together for the midterm; the investment memo at class 14 pulls all twelve together for demo day, and the Venture Book is the case study that shows how you got there.
