ICP and Buyer Research

A lot of channel failures are ICP failures that took six months and a budget to surface. Before you spend against a buyer definition, it is worth testing whether that buyer exists, holds the budget, and is anywhere near the place you plan to reach them. We interview people who recently bought in your category, including the ones who bought from a competitor and the ones who decided to do nothing.

Who We Ask

Sourcing and screening

Every expert is at least six months removed from any company they are asked to discuss. No material non-public information may be requested or shared, calls are monitored, and the audit trail is kept for seven years under the FieldSignal compliance framework.

What was happening in your business the week you decided to solve this?

Where were you looking, and what did you type or ask when you started?

Q.04

What nearly stopped you buying, and what did the vendor do that helped?

Q.05

Which vendors did you rule out before speaking to anyone, and why?

Q.06

Six months on, would you buy it again?

Buyers To Stop Chasing

Segments that do not survive contact
06.1
The enthusiastic non-buyer

Takes every meeting, gives excellent feedback, holds no budget. Entire pipelines get built on this person because the activity metrics look healthy right up until the quarter closes.

06.2
The user who is not the purchaser

Targeting the person who will use the product when a different function signs the contract produces high engagement and low revenue. It is common in tools sold into operations, and it usually shows up as a stalled stage rather than a lost deal.

06.3
Segments that only close with heroic sales effort

They do close, so nobody questions them. They also consume several times the sales cost of an adjacent segment, which only becomes visible when someone measures cost to acquire per segment instead of in aggregate.

06.4
The aspirational logo tier

Large accounts that appear in the plan because they would look good on the website. Usually a different product, a different cycle length and, honestly, a different company.

06.5
The side of the marketplace nobody owns

In two-sided businesses one side tends to get the budget and the other gets hope. In the live-lessons engagement, demand and supply needed completely different channels, and only one of them was being funded.

06.6
The buyer you inherited from the pitch deck

Fundraising narratives calcify. A definition written to make a market look big is not the same as one written to make targeting work, and the two drift apart quietly.

A Worked Example

Anonymised, published in full
07.0
A marketplace for live lessons
The situation
The company ran a marketplace for booking live lessons and masterclasses from experts. It had two sides: learners who buy and creators who teach. Growth spend was going out with no clear read on returns.
What we did
We split the research by side, measuring the demand side to completed bookings rather than clicks or views, and reading creator acquisition on teachers who actually published and stayed active.
What came back
Learners searched for the specific skill they wanted, so search converted and paid social filled the funnel cheaply without closing bookings. Supply behaved completely differently: active teachers introduced other experts far more cheaply than paid acquisition ever did. The two sides needed separate channels and separate budgets.

What This Will Not Tell You

Limits, stated upfront

Every research method has a boundary. Here is where this one sits, so you can decide before you commission it rather than find out at the read-out.

08.1
Buyers reconstruct their reasoning

People rationalise after the fact. We ask about sequence and specific events rather than motivation, because what someone did in a given week is far more reliable than why they say they did it.

08.2
Lost deals are hard to reach

Buyers who chose a competitor are the most valuable interviews and the least willing. We get them more often than not, and we tell you the achieved split rather than quietly filling the gap with easier interviews.

08.3
It will not size your market

This tells you who buys and why. How many of them exist is a different question, and /use-cases/market-sizing is the engagement for it.

08.4
Redefining the ICP is the easy part

Acting on it means changing targeting, messaging, comp plans and sometimes the roadmap. We can tell you what the buyer research says. Whether the organisation will accept it is not something research decides.

Questions

5 answers
01How is this different from talking to our own customers?
Your customers already chose you, so they can only explain why the current motion works. This deliberately includes buyers who chose a competitor and buyers who chose nothing, because that is where the positioning and channel problems are visible.
02Do you produce personas?
No. Personas are a summary format that tends to outlive the evidence underneath them. You get the buyer definition, the committee, the triggers, the segments we ruled out, and the interviews they came from.
03We already have an ICP. Can you just test it?
Yes, and it is the faster and cheaper version. Send us the definition and we will interview against it, then report which parts held, which did not, and how confident we are in each.
04How many interviews does this take?
Usually fifteen to thirty, split across current buyers, competitor buyers and no-decision buyers. Below about twelve you cannot separate a pattern from a personality.
05Will you talk to our existing customers?
If you want us to, yes, and it is often worth including a few for contrast. We would not build the engagement on them, for the reason above.
