In a standard portfolio company review, the marketing section of the board pack contains three types of data: channel spend, attributed conversions, and cost per acquisition. These numbers are accurate. They describe what the paid search budget purchased last quarter. What they do not describe is the demand that existed in the market but was never reached.
This distinction matters in a PE context because the growth thesis is almost always predicated on category expansion as well as conversion improvement. A company can improve its conversion rate continuously while its share of total category demand declines. The board pack will not show this. The growth thesis will remain unchallenged until the revenue line fails to move.
The structure of a demand gap
A demand gap has a specific structure. It is the difference between three things: the demand a company captures, the demand its visibility reaches but loses to competitors, and the demand in its category that it does not appear in front of at all.
Standard reporting measures only the first. Attribution tools record conversions from arrived traffic. They cannot measure what did not arrive, because measurement begins at the click.
Every capital allocation decision made from standard reporting is made against an incomplete picture of the market. Not slightly incomplete. Structurally incomplete. The demand that exists but does not arrive leaves no data behind.
What this looks like in practice
In the five anonymised case studies, the pattern is consistent. Between 56.3 and 92.6 per cent of captured demand comes from searches for the business name. People who already know the company find it when they search for it by name, which creates the impression of strong search performance.
Category-level demand tells a different story. When potential customers search for the problem the company solves, without already knowing the company by name, the visibility mostly goes to competitors: Demand Leakage in the same five cases ranges from 82.0 to 99.7 per cent.
The paid search budget then operates in this environment. A portion of that spend is intercepting branded demand that would have arrived organically. A portion is attempting to reach category demand that the organic presence cannot capture. Attribution records both as paid conversions. The budget justifies itself. The structural problem remains invisible.
Why this is relevant to the value creation plan
Demand Leakage and Untapped Potential show where growth can start. A company that reduces its leakage in category searches lowers the cost of acquiring the same volume. A company whose leakage grows against a growing category depends more on paid spend, whatever reported ROAS suggests.
In a 100-day plan, the standard question is whether the growth thesis is achievable given current commercial conditions. Demand Leakage answers a more specific version of that question: is the company visible to the demand it is trying to convert, before any capital is committed to converting it?
Not: should we spend more on marketing? But: there is a quantified demand gap, driven by a specific structural failure. Does correcting it belong in the value creation plan?
