The Law of Validation

What this means

Validation is information, not approval. It's the smallest experiment that would change your mind about what to build next.

The teaching

Validation is not approval. It is information. A landing page, a waitlist, ten honest conversations — these are cheaper than a year of building something nobody wants.

Why it matters

Building without evidence is the most expensive way to learn. A landing page, a waitlist, ten honest interviews — each is cheaper than a year of building the wrong thing.

Practical application

Pick the smallest experiment that would change your mind. Run it this week.

Common mistakes

• ·Treating excitement from friends as proof of demand.
• ·Mistaking page views for buying intent.
• ·Skipping validation because it feels slow or unglamorous.
• ·Validating the solution before the problem.
• ·Building a landing page that describes a brochure instead of testing a promise.

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?

Practical exercises

• Publish a single-page landing page with one promise and one CTA. Drive 200 visits.
• Run 10 customer interviews and tag the patterns.
• Open a waitlist with a clear ask: 'leave your email if you'd pay $X for this.'
• Pre-sell to 5 people before building anything.

Real examples

• A founder built a $0 landing page in an afternoon and gathered 84 emails in a week — enough signal to pursue the idea seriously.
• Another founder skipped validation, built for 9 months, and discovered post-launch that the audience didn't exist.
