How to read buyer intent from public signals before you build anything

Someone spent three months building a course.

It sold four copies.

The complaints that would have told them not to build it were sitting in a Reddit thread. Public. Free. Posted six weeks before they started.

Most people skip it because it doesn't feel like work. It feels like scrolling.

The difference between scrolling and reading signals is what you're looking for.

Buyers leave traces everywhere. Not in surveys. Not in focus groups. In the places they go when they're frustrated, when something didn't work, when they're trying to solve a problem at 11pm and nobody is helping them.

Those places are public. The traces are readable. The skill is knowing where to look and what the signal actually means.

Wall Street just bet billions on a small collection of stocks.

And after a volatile first half of 2026, it looks like they’re about to shift even more.

Go to any subreddit, Facebook group, or forum where your target audience gathers. Search for words like "frustrated," "nobody," "why doesn't," "I can't find," "does anyone know." What comes up is a live inventory of unmet needs. Not hypothetical needs. Actual problems someone was frustrated enough to post about publicly.

A complaint posted publicly is a confirmed problem. The person wasn't venting to themselves. They went looking for a solution and didn't find one. That gap is your product brief.

Go to the bestselling product in your niche. Read every review under three stars. Not to find flaws in the product. To find the expectation that wasn't met.

One-star reviews are rarely about the product being bad. They're about the promise not matching the delivery. The promise that didn't land is the thing the buyer actually wanted. That thing, delivered properly, is your offer.

Go to the comments under your competitors' content. Sort by recent. Read the questions. When the same question appears more than twice across different posts, it's not a question anymore. It's a gap in the market that the competitor hasn't closed.

The question that keeps appearing is the article nobody wrote. The product nobody built. The thing your audience is ready to pay for the moment someone answers it well enough.

The mistake most builders make is reading the surface of the complaint. Someone says "I tried three tools and none of them worked." The surface reading is: build a better tool.

The deeper reading is: this person has already spent money trying to solve this problem. They are not price-sensitive. They are outcome-sensitive. They will pay again for something that actually works. The signal isn't just "what to build." It's "this buyer is already in motion."

That distinction changes how you position what you build. Not "here is a tool." "Here is the thing that works after the three things you already tried didn't."

Pattern recognition applied to markets works exactly like pattern recognition applied to people. You're not reading the words. You're reading what the words reveal about the state the person is in.

Someone asking "why doesn't X work" is in a different emotional state than someone asking "what's the best X." The first person is frustrated and nearly ready to pay. The second person is still shopping.

Read the frustration signals. That's where the buyers are.

Pick one product in your niche. Go to its reviews on any platform. Read the one and two-star reviews only. Write the positioning sentence:

"People who [situation] want [outcome] but keep hitting [obstacle]."

Reply with your sentence. I'll tell you if it's ready to build from.
