How to find whitespace in the supplement market · Chapter 3 of 9 · 3 min read

Look for whitespace in problems, audiences and formats

The reflex of every founder hunting an opportunity is to hunt an ingredient. As a first step, it's the wrong reflex: ingredients are the market's most visible layer, and therefore the fastest exploited. The gaps that last longer live one floor below — in the problem you solve, the audience you address and the format you package it all in.

The same market that looks saturated at ingredient level can have a whole problem served poorly: plenty of searches, few or generic ads, no coherent positioning.

What you'll be able to do after this chapter

  • map a category's problems: which one gathers thousands of ads and which is nearly empty;
  • use the automatic discoveries in Explore as a starting point, not a verdict;
  • check whether a problem gap is real or just badly labelled.

The principle

A problem is an opportunity when the attention exists and the coherent offer is missing. The signs: people search for it (chapter 5 confirms), a few ads touch it in passing, but nobody has built their positioning around it. Conversely, a problem with thousands of active ads isn't necessarily closed — but there you no longer compete on "I saw the gap"; you compete on execution, and that's another book.

Audience and format cut the market on other axes: the same problem can be saturated for the general audience and free for a specific one; the same ingredient crowded in capsules and empty in another format. The compound gaps — problem × audience × format — are the hardest to see with the naked eye, and that's exactly why they last.

The workflow in RavenBI

  1. Open Explore on your market. The discovery sections (Breaking and Unexpected discoveries) are the starting point: here the radar surfaces daily the patterns you wouldn't have searched for — recipe convergences, new white spaces, ingredients freshly authorised as novel foods in the EU.
  2. Go down to the market map by category and open yours — you see how many brands crowd it and how the ads are distributed inside it.
  3. Switch to the Ad Library and use the Problem facet: the distribution of classified ads across problems. Note the extremes — the themes with thousands of ads and the nearly empty ones.
  4. For a seemingly empty problem, open the few ads that exist: are they dedicated positionings, or passing mentions by general products? The real gap is the second case.
  5. Repeat the analysis on audience and format from the dedicated Explore pages — same logic, other axes.

Explore in RavenBI

The day's discoveries in Explore — convergences, white spaces, regulatory changes — the starting point when you don't yet know where to look.

How to read the signals

  • A problem with many searches and few dedicated ads = the classic whitespace candidate — goes straight onto the checklist for chapters 5 and 6.
  • A problem with many old, active ads = proven demand, narrow window — enter only with clear differentiation.
  • A problem with many new ads and few old ones = a market in testing; nobody has validated yet — you can wait to see what survives.
  • An Explore discovery with a high score = a qualified hypothesis, not a decision: you owe it the same demand-and-claim verification as any idea of your own.

The typical mistakes

  • starting with the ingredient and stopping there — the market's fastest-exploited layer;
  • taking "few ads" as a gap without checking whether demand is zero too (chapter 5 exists exactly for that verification);
  • ignoring the compound axes — the gap is rarely on a single one;
  • treating the automatic discoveries as a shopping list — they're the start of the investigation, not its end.

Exercise

Take your category from chapter 2 and pull the two extremes from the Problem facet: the most crowded problem and the worst served one. For the second, open the existing ads and answer a single question: is there at least one brand that built its positioning around it? If not — you have your first concrete whitespace hypothesis. Write it on the sheet.


The problem hypothesis needs a vehicle: an ingredient or formula that solves it credibly. The next chapter returns to ingredients — but with the right instruments: demand face to face with ad pressure, not impressions.
