August 2026 · Buying behavior

The funnel never measured the buyer

Everyone quotes the 17%. Gartner did the division. Almost nobody selling has.

Everyone in B2B knows the 17% number. Or one like it. Buyers spend an increasingly small percentage of their total buying process in direct contact with suppliers.

I have quoted it in keynotes. I have put it on slides. I have used it to open workshops.

And for years I never did the division.

There are three to five vendors in a serious enterprise evaluation. Taking my example of 17% (per Gartner), this is the total time - it is not yours. It is split. Do the math and any one seller gets somewhere around 5% of the buyer's attention across the entire decision.

Five percent. That is the whole window. Every call, every email, every demo, every follow-up, added together.

Then it gets worse.

The 5% is not a chance to persuade

By the time a buyer talks to you, they already have a preferred vendor in 4 out of 5 cases. They started that conversation themselves 79% of the time. And in 95% of deals the winner is one of the four vendors that was on their day one list, assembled before a seller said a word.

Read those together and the picture changes shape.

Your 5% is not an opening argument. It is a confirmation hearing.

The buyer has done the research, formed a view, and is checking whether reality matches it.

You are not persuading anyone. You are being verified.

That is a different job than the one most playbooks are written for, and most sellers are still preparing for the wrong one.

Why the funnel cannot see any of this

Here is the part that took me longer to accept than it should have.

The funnel was never a map of the buyer. It is a map of us.

Look at what it measures. Stages. Stage exits. Conversion rates. Activity counts. Days in stage. Every one of those is a seller behavior with a timestamp on it.

None of them is a buyer decision. You may be at "Stage-2: Qualify," but the buyer is at "Stage-5: Verify and commit."

So the 95% is not just unmeasured. It is unmeasurable by that instrument. Research, internal debate, the Slack thread you will never see, the meeting where two people who never took your call decided you were too risky. The funnel has no field for any of it.

Which is why deals "stall" that were never moving. And why forecasts miss on decisions made in rooms no seller attended.

You are not selling to a person anymore. You are selling to a consensus that formed without you.

What I keep hearing

I have had a version of this conversation four separate times in the last two weeks. Medtech. Enterprise software. Financial services. Different industries, same shape.

The seller has more tooling than ever. More data, more automation, more dashboards. And they still cannot answer two simple questions:

  1. What happened in the eight weeks before this account raised their hand?
  2. What is happening between your last meeting and the next one that determines whether your deal is thriving or dying?

Nobody is short of activity. Everybody is short of visibility into the part that decides the outcome.

That gap is not a tooling problem. It is a design problem, and it starts with what you chose to measure.

What actually changes

If the buyer decides mostly without you, then the work moves.

It moves earlier, into reading the signals a buyer throws off before they engage. A leadership change, a public growth target, a hiring pattern, a reorg. Those are not noise. They are the only view you get of the 95%.

It moves into preparation, because a confirmation hearing rewards the person who arrives already understanding the situation. Not the person who arrives ready to discover it.

And it moves after the call, into capturing what you learned so the next person selling into that account starts from what you found rather than from zero. Most organizations lose this entirely. The insight lives in one rep's head, and when they leave, it leaves.

None of that is a technology purchase. It is a system design question, and the answer differs by company.

That is the argument our DS3 course at Kellogg is built on. This is Class 1 of Designing Scalable Selling Systems, which Craig Wortmann and I start teaching September 21: why selling changed, and what to rebuild first.

The net is this. If you only get 5% of the attention, and you get it after the decision has mostly formed, then the highest-leverage work in selling is no longer what you do in the meeting. It is what you knew before it, and what you keep after it.
