Validation

What this stage is

Validation is not approval. It is the smallest experiment that would change your mind about what to build next. It is information about real-world demand, not encouragement from friends.

Why it matters

Validation reduces the cost of being wrong. A landing page, a waitlist, ten honest customer interviews — each is cheaper than a year spent building something nobody wants. This is the stage where most founders save (or lose) the most money.

Common mistakes

• ·Treating friends' enthusiasm as proof of demand.
• ·Skipping validation because it feels slow or unglamorous.
• ·Building a landing page that's a brochure instead of a test.
• ·Confusing page views with buying intent.
• ·Validating the solution before the underlying problem.
• ·Stopping at validation — never converting it into actual demand.

Reflection questions

• ◆What evidence would make me stop building?
• ◆What is the cheapest way to learn the next thing I need to know?
• ◆How many strangers (not friends) have given me money, time, or attention?
• ◆If only one of my assumptions is wrong, which one would hurt most?
• ◆What does 'enough' validation look like before I commit to building?

Real examples

• A founder gathered 84 emails in 7 days with a $0 landing page — enough signal to pursue the idea full time.
• Another founder built for 9 months without validation and discovered post-launch that the audience didn't exist as imagined.
