What is user validation for SaaS products?

User validation is the process of testing your SaaS product assumptions with real users before development. It helps founders eliminate uncertainty by gathering measurable feedback on whether users understand the product value, can complete core actions intuitively, and find the “aha moment” naturally. Validation provides proof instead of opinions, preventing costly development of features users don’t need or understand.

How many users do you need to test for MVP validation?

You need 3-5 user tests to reveal 80% of your product’s usability issues. Test with people who resemble your target cognition, not just demographics—recruit users who actively experience the problem your product solves. Avoid testing with friends, peers, or investors who already understand your idea and will subconsciously fill in gaps, giving false positives.

What metrics should you track during user validation?

Track four key validation metrics: (1) Task Completion Rate—percentage of users who successfully complete the flow (target: 80%+), (2) Error Rate—how many attempts failed or ended in frustration, (3) Time on Task—average duration to finish the flow (large variations indicate confusion), and (4) Effort Score—user-rated difficulty on a 1-5 scale. These quantify clarity and remove bias from design decisions.

What tools do you need for SaaS MVP validation?

Use a minimal validation stack: Figma and FigJam for mapping flows and building clickable prototypes, Maze for remote usability testing and automatic metrics tracking, Notion for organizing documentation and validation summaries, Zoom for live moderated sessions, and Loom for recording async feedback recaps. This focused toolkit maximizes learning velocity without tool bloat.

How do you create a validation prototype?

Build a clickable Figma prototype focused on logic, not aesthetics. Create 3-7 connected screens showing entry point, core action, and success state. Ensure every button leads somewhere with no dead ends. Include light micro-feedback like confirmation messages. The prototype should simulate the complete core user action from start to finish, testing whether your mental model matches users’ comprehension.
