How to Validate a SaaS Idea Before Writing Any Code
The pre-code SaaS validation loop: problem interviews, landing tests, manual-mode delivery, and the smallest experiment that proves willingness to pay.

You do not need to write code to know if a SaaS idea works. In fact, writing code first is how most solo founders waste six months. Here is the pre-code validation loop.
The three artifacts you build before the product
None of these require a developer.
- A one-page site that promises the outcome
- A manual-mode delivery process (you do the work by hand)
- A pricing page with a working checkout link
The order that saves months
1. Land the problem statement in interviews. 2. Ship a smoke page and measure conversion. 3. Deliver the first outcomes manually. 4. Charge from customer #1. 5. Only then, automate what breaks first.
The bar to clear before coding
Three paying customers, at least one non-friend, retained for a second month. That is the minimum evidence to justify a build. Below that, code is a distraction.
