Who pays, why, how money comes in, what it costs.
In Founder mode, open PROVE in the founder sidebar and choose Business Model. It answers how your business would create, deliver and capture value. A business model here is a hypothesis that needs evidence — not a business plan, not your accounts and not a fundraising page.
Press Create Business Model and pick the solution it is for — or an opportunity, a problem, or Create without linking. From Solution & Prototype, the Business Model link opens this with the solution already chosen. The customer, the value and what people use today are filled in from what you linked, so you do not write them twice; check them.
On Customer & value, describe the customer segment you are building for first, then who uses it, who decides to buy and who actually pays — they can be three different people, so tick Same as only when they really are. Describe the value it creates and why someone would pay for it, including what they pay for today.
On Revenue & pricing, pick the primary revenue model — subscription, transaction fee, marketplace commission, usage-based, licensing, enterprise contracts, advertising, services, freemium or hardware + software — and any secondary streams. Each one asks its own questions. Write a first pricing idea and where it stands, then press Continue to Pricing to research and test it; the Pricing form opens filled in.
On Costs & economics, tap each cost that applies (development, infrastructure, support…), say roughly how much and whether it is known, estimated, an assumption or unknown, and whether it stays the same or grows with customers. Then use the simple view (price, delivery cost, contribution) or full unit economics. Leave a number blank if you do not know it — it says Not enough data yet. Real money stays in Finance.
On Assumptions & evidence, list what must be true — for example that customers will pay at this price — and mark each untested, testing, supported, contradicted or changed. Add evidence such as an interview, competitor pricing, a pre-order or an actual sale; each is marked as something people said, research, something people did or money that changed hands. Add your biggest unanswered questions.
Where it stands shows a Business Model Check in words — for example Customer defined, Pricing a hypothesis not yet tested, Unit economics insufficient data — and what you know, believe and do not know. There is no score. The page suggests one next thing to learn, such as testing pricing with potential customers or estimating delivery costs.
Not sure which model fits? Add another option for the same solution and press Compare options to see them side by side. Nothing picks a winner. When you want to build around one, mark it Chosen for now after a short review — it stays a hypothesis — and Product & MVP is the next place to go.
