Three blind spots in go-to-market data

Most go-to-market data has three predictable blind spots: it observes the wrong time, studies the wrong sample, or describes customers in the wrong language. Each one produces a confident, internally consistent picture with the causal information removed — which is why teams can run diligent win/loss reviews, watch health scores weekly, and hold quarterly messaging workshops while the same problems recur.

None of these are failures of effort. They are failures of instrument.

01 · Temporal Wrong time

The signal arrives after the decision

Usage data precedes the cancellation, not the decision — and the decision is the only thing you could have influenced. By the time an account looks at risk, you are confirming a verdict rather than forecasting one.

Shows up as: health scores turning red too late, save plays aimed at a decision made months earlier.

02 · Sampling Wrong sample

Only deciders are in the data

Win/loss interviews buyers who crossed the decision threshold. Everyone who never crossed it is absent. That is selection bias in the ordinary sense, and it removes the largest outcome category from the study of outcomes.

Shows up as: win/loss findings that never explain the pipeline, closed-lost codes reading budget and timing.

03 · Linguistic Wrong language

The words came from inside the building

Positioning frameworks tell you what to decide, not what customers say — and the questions about buyers get answered in a workshop. The output is accurate and unrecognisable: buyers cannot see themselves in language they never use.

Shows up as: messaging everyone internally likes that converts poorly, four buyer roles served by one sentence.

What the three have in common

Each blind spot substitutes something observable for something causal. Usage stands in for intent. Deciders stand in for the market. Internal consensus stands in for customer vocabulary. In every case the substitute is easier to collect, arrives in a dashboard, and quietly answers a different question than the one being asked.

The correction is the same in all three: talk to people, at the right moment, including the ones who did not buy, and record what they actually said. That is unglamorous and it is why the gaps persist.

Where the interview guides fit

Each article ends at an instrument. The churn guide reconstructs when a decision was really made. The no-decision guide covers the population that never appears in win/loss. The core jobs guide is built to be run across all four buyer roles and to capture exact phrasing.

If you want help running them

Diagnosis is the part that does not scale on its own.

Reaching the right people — including non-buyers and churned accounts — and coding what they say into something you can act on is where most self-run studies stall.

AI-moderated interviews when you need reach across a larger sample. 1:1 expert interviews when you need the deepest read on a small number of people. Fully managed from recruitment through findings, or hybrid — working alongside your team, running interviews jointly and presenting together.
