If you make it first, you'll go down first. You have to create something that customers will buy.

Why Developers Should Sell a 'Demo' Before Coding
#DemoSellBuild #LeanStartup #PMF #MVP
🫑 3-Line Summary
•
The traditional 'Build → Demo → Sell' approach is a dangerous method that focuses solely on technology development while ignoring market risks.
•
Ash Maurya suggests reversing the order to 'Demo → Sell → Build' and recommends selling the 'value (promise) the product will provide' first instead of a working product.
•
In a real-world example, a founder who planned to spend two months developing the product secured a paid pilot contract the very next day with just a single 'report sample,' proving that customers buy 'results' rather than features.
🥦 Insight
•
Ask "Will it sell?" first, not "Can I make it?"
Thanks to no-code and AI, making things isn't difficult anymore. The real problem is "working hard on it, but nobody buys it." It is much safer to ask customers, "Would you like to buy this?" before you start coding.
•
The demo is not a 'feature manual', but a 'movie trailer'.
The purpose of a demo is not to show how the product works. It is to show the 'story' of how using this product will improve the customer's life. Rather than a flashy demonstration of features, a single 'result' (e.g., a sample report) that solves a customer's problem becomes a more powerful sales tool.
•
Customers are slower than you, don't be afraid.
"What if I say I’m selling it now, but they demand I release it immediately?" Don't worry. Enterprise clients take months just for budget approval and legal review. That is enough time to build it. Selling first and then building while the client waits is the surest motivation for development.
🥄 A spoonful of execution
•
If you are currently working on a feature, pause for a moment and create an image or document of what the finished product will look like. Then, show it to a potential client and ask, "Would you like to sign the contract for this deliverable right now?"

The role of a demo is not to show how the product works.
It tells the story of what the product conveys.

👋 Hello, this is David!
Introduction.
Most founders do this when an idea comes to mind:
1.
We spend weeks or months building a product or MVP
2.
Session demos with potential customers
3.
Try selling for a few more weeks or months.
This is the traditional Build → Demo → Sell approach.
Ash Maurya says: There is a much better way.
We guarantee that it is 3 times faster, has a 3-5 times higher conversion rate, and makes only what customers want.
