One of the biggest monetisation mistakes made by founders.
| Aspect | Sell Before You Build | Build Before You Sell |
| ----------------------- | ---------------------------------------------- | ------------------------------------------- |
| **Market Validation** | Confirms demand before effort | Risks building something no one wants |
| **Resource Efficiency** | Focuses resources on validated needs | May waste resources on unneeded features |
| **Customer Feedback** | Immediate feedback guides development | Feedback comes after significant investment |
| **Risk Mitigation** | Reduces financial and market risks | Higher risk of market rejection |
| **Time to Market** | Faster, as development is streamlined | Longer, due to full development cycle |
| **Product-Market Fit** | Achieved more easily with early customer input | Might need drastic pivots |
| **Cash Flow** | Revenue before launch | Delayed revenue after launch |
