What is a business model canvas, and how do I fill one in?
The Business Model Canvas is a one-page template, created by Alexander Osterwalder at Strategyzer, that shows how a business makes money in boxes: customer segments, value propositions, channels, customer relationships, revenue streams, key resources, key activities, key partners and cost structure. Fill it in pencil, customer side first: who buys, what you promise them, how you reach and keep them, what they pay; then the resources, activities, partners and costs it takes to deliver that. Every box is a guess to test with customers. Before you have a product, Ash Maurya's Lean Canvas is the startup version, swapping in problem, solution, key metrics and unfair advantage.
The book that introduced the canvas, co-created by 470 practitioners from 45 countries, with worked examples of business models taken apart box by box.
Steve Blank's definition of a startup as an organisation formed to search for a repeatable and scalable business model, and why that makes it different from running a known business.
A one page template that forces you to write down the problem, the customer, and why you are placed to solve it, all on a single sheet you can revise fast. Filling it in surfaces the weak spots in your idea quickly, especially whether the customer group is reachable and the problem is specific. Use it as a scoring sheet for a new idea rather than a formal business plan.
The actual one-page canvas, free to print or copy into a doc, so you can fill it in within the hour instead of reading a whole book first. Use it before your first round of customer conversations to write down what you think is true, then use it again after to see what actually changed.
A one-page tool for writing down what you have learned about a customer's jobs, pains, and gains, then checking whether your idea actually addresses them. For an outsider it forces you to fill the customer side first, from real research, before you let yourself describe a solution. Print it and revisit it after every batch of interviews.
