How to validate a SaaS idea before writing a line of code

Executive overview

Most founders waste months building a product nobody wants. They start with code instead of confirming there's a real market first.

The fix is a three-step sequence: market, then go-to-market, then product. Each step gates the next.

Build the go-to-market plan before the product, not after.

Principle 1: Start with market, not product

• Identify a specific target customer group before anything else.
• Define the urgent and important problem you're solving for them.
• If you can't articulate urgency, the market probably isn't large enough to support a business.
• Writing this down forces honesty — vague ideas dissolve under the test.

Principle 2: Validate before you build

• Write a clear value proposition: who it's for, what problem it solves, what value it delivers.
• Get into as many prospective customer conversations as possible.
• Don't ask for opinions — ask how urgent and important the problem is for them.
• Ask how they've tried to solve it already; this surfaces the real competition.
• Try to sell them on the solution before it exists — genuine interest is the signal.
• Outcome 1: a warm list of buyers ready when the product ships.
• Outcome 2: validated (or killed) market thesis with no development cost.

Principle 3: Build a 10X product

• Only start building once market and go-to-market are confirmed.
• Use customer conversations to understand what alternatives people currently use.
• Set the bar at 10X better than the default — meaningfully superior, not marginally different.
• Return to the same prospects with the finished product; they already trust you.
• Initial revenues follow because the pipeline was built during validation.
