THE SHORT ANSWER
A startup business model states who receives value, who pays, what they pay for, when and how payment occurs, what it costs to deliver, and what must repeat for the business to work. The right model depends on customer behaviour, market structure, costs and strategic constraints.
Describe the value and money flow
- Who uses the solution?
- Who pays for it?
- What outcome, access or transaction is being purchased?
- Is revenue one-time, recurring, usage-based or mixed?
- Which partners participate in delivery?
- Which costs grow with each customer or transaction?
- What behaviour must repeat?
Common models create different constraints
| Model | Revenue event | Operating implication |
|---|---|---|
| Subscription or SaaS | Recurring access or usage | Retention and service cost matter |
| Transaction or commission | A completed exchange | Liquidity, trust and take rate matter |
| Marketplace | Facilitated supply-demand transaction | Both sides and marketplace quality matter |
| Direct sale | Product or project purchase | Sales cycle and delivery margin matter |
| Freemium | A subset upgrades | Free-service cost and conversion matter |
| Advertising | Audience attention or response | Scale, suitability and dependence matter |
| Service plus product | Service revenue and product access | Founder effort and repeatability must be separated |
| Licensing | Permission to use an asset or capability | Rights, enforcement and support matter |
Test the model, not only the product
A solution can be useful while its payment model fails. Test who controls budget, what unit they expect to buy, when value becomes visible and which alternatives anchor the decision.
A manual early service may prove demand while concealing a delivery cost that prevents scale. Record founder labour and support even when no cash leaves the bank.
Evidence & context: Strategyzer
Connect revenue to delivery economics
Estimate price, variable cost, gross margin, acquisition effort, retention and cash timing under more than one scenario. The Break-even Calculator can expose the volume implied by a price and cost structure.
Next, treat pricing as a customer and economics hypothesis rather than a final number chosen once.
