#186 — The 95:5 rule: Why most of your GTM is wasted
July 1, 2026·5 min read

Contents
The big picture: At any given moment, only 5% of your B2B buyers are actually in-market. The other 95% aren't ignoring you — they already have what you're selling, are locked into a competitor contract, or simply won't need a solution for months or years.
Why it matters: Your entire GTM motion is probably optimized for the 5%. That's not a strategy — it's a treadmill.
Where the 5% Comes From
Professor John Dawes of the Ehrenberg-Bass Institute observed a simple truth: B2B companies switch vendors roughly once every five years. Do the math — that's ~20% in-market in any given year, and only ~5% in any given quarter.
This isn't a fixed law. It's a mental model. If you know your category's average repurchase cycle, run the calculation yourself. But whatever the ratio, the implication is identical: the overwhelming majority of your potential customers cannot buy from you right now — not because they don't want to, but because they structurally can't.
The Shortlist Problem
The real danger isn't that buyers aren't ready. It's that by the time they are, the decision is already made.
- 80–90% of B2B buyers arrive at the research phase with a vendor shortlist already formed
- 9 in 10 go on to select a provider from that day-one list
- Rational "buy now" ads have short-term recall only — buyers won't remember a campaign they saw 18 months ago when they finally come in-market
If your brand isn't in their head before they start looking, you're not losing a deal — you were never in the running.
What to Do About It: The Budget Split
Dawes' rule explains why brand building matters. Binet & Field tell you how much to invest.
Their B2B-specific research puts the optimal marketing budget split at:
- 46% brand building — long-term, emotive, memory-forming
- 54% short-term activation — conversion, pipeline, performance
For founders, this is the hardest pill: nearly half your marketing spend should go toward people who will not buy from you this quarter. That's the job.
The Three Misapplications Founders Make
1. Confusing 95:5 with Pareto's 80/20. The 80/20 principle says focus your effort on the highest-yield actions. Applied wrongly here, it suggests 95% of your marketing is waste and you should hammer the 5% in-market with everything you've got. This is exactly backwards.
Yes, all revenue comes from the 5% — but only "at any given time." The 95% become the 5% on a rolling basis. Ignoring them means you're invisible when they flip.
2. Treating brand spend as unattributable waste. Your CFO will want to cut anything that doesn't show up in last-click attribution. Preempt this. The data is clear: companies that sustain brand investment through downturns compound growth; those that cut it stagnate. Binet & Field's long-term growth curve is the most compelling chart you can put in front of a skeptical board.
3. Conflating 95:5 with long:short. These are complementary frameworks, not the same thing. 95:5 is the rationale — it explains why long-term brand building deserves budget. Long:short (Binet & Field) is the prescription — it tells you how to split it. Use 95:5 to win the internal argument; use long:short to allocate the budget once you've won.
How to Sell This Internally
The 95:5 rule works where other frameworks fail because it's viscerally intuitive for non-marketers.
I have used the 95:5 rule in B2B with non-marketing senior managers and they get it. They don't get long and short. They don't get brand building. They don't get any of it. But the 95:5 rule — they say, 'Huh! I get it. We need to prepare the 95 for when they turn into the five.'
— Mark Ritson
Use this framing with your co-founders, investors, and board. "Brand spend" loses the room. "Priming the 95% before they enter the market" wins it.
The Founder Playbook: What to Do Now
- Audit your current spend. What percentage is pure performance/activation? If it's above 80%, you're over-indexed on the 5%.
- Calculate your category's repurchase cycle. If you're in a space where buyers switch every 2–3 years, you may have a higher in-market ratio — but the principle still holds.
- Start brand-building content now, not when pipeline is thin. Thought leadership, founder POV, category education. The goal is memory — not clicks.
- Build your shortlist position. The question isn't "how do I win the deal?" It's "how do I get on the list before the deal starts?" Own a clear, distinct position in your category so that when a buyer forms their mental shortlist 18 months from now, you're on it.
- Protect brand spend in downturns. This is where compounding happens and where most early-stage companies defect.
The bottom line: The founders who win at scale aren't the ones who converted the most buyers this quarter — they're the ones the entire market already thought of first.
Frequently asked questions
How do I know if I'm over-indexed on performance marketing?
If more than 70-80% of your marketing budget goes to paid ads, retargeting, or bottom-funnel conversion campaigns, you're almost certainly over-indexed. The Binet & Field benchmark for B2B is 46% brand / 54% activation — most early-stage startups run closer to 90/10 in favor of activation. A quick audit: pull your last 6 months of marketing spend and categorize every line item as 'converts now' or 'builds memory.' The imbalance will be immediately obvious.
What does B2B brand building actually look like for a startup with no budget?
Brand building isn't about TV ads — it's about consistent mental presence in your category before buyers are ready to shop. For founders, this means: a clear and ownable point of view published regularly (LinkedIn, newsletter, podcast), thought leadership that names the problem you solve before pitching the solution, and content that educates the 95% who aren't ready to buy yet. Notion, Linear, and Loom all built substantial brand equity early through founder-driven content before spending on paid channels.
What are category entry points and why do they matter for early-stage startups?
Category entry points (CEPs) are the specific situations, triggers, or emotions that cause a buyer to think of your product category — not your brand specifically, but the entire space you operate in. For example, a startup selling contract management software would want to own CEPs like 'closing a new enterprise deal,' 'onboarding a vendor,' or 'legal team flagging a renewal.' Brands that link themselves to the most common CEPs in their category get recalled first when buyers enter the market — which means you make the shortlist before a competitor even gets a meeting.
Should I invest in brand building during a downturn or when runway is short?
Counterintuitively, yes — protecting brand spend during downturns is where compounding happens. Binet & Field's long-term growth data shows that companies which cut brand investment during contractions recover more slowly and lose market position that's extremely difficult to reclaim. If budget is genuinely constrained, cut paid activation before brand — organic thought leadership, founder content, and earned media cost time, not cash, and continue building mental availability through the contraction.
How do I measure the ROI of brand building when my CFO wants attribution on everything?
You can't attribute brand spend the same way you track a Google Ad click — and trying to will misrepresent its value entirely. Instead, track leading indicators: branded search volume growth, direct traffic trends, win rate on deals where your brand was already known versus cold outbound, and time-to-close. One B2B service firm found that brand investment generated a 2,400% ROI when measured against customer lifetime value rather than last-click conversion. Present your CFO with Binet & Field's long-term growth curve — it's the most compelling argument available.
Why do 9 out of 10 B2B buyers pick from a pre-formed shortlist?
B2B purchases are high-stakes, infrequent, and involve multiple stakeholders — so buyers de-risk by relying on brands already stored in memory rather than conducting exhaustive vendor searches from scratch. HBR research found that 80-90% of buyers arrive at the research phase with a vendor list already in mind, and 9/10 select from that list. The shortlist is formed passively over time through brand familiarity — not by the salesperson who reached out last week. This is why being invisible during the 95% phase is catastrophically expensive even if it doesn't show up in your quarterly funnel.
How is the 95:5 rule different from Pareto's 80/20 principle?
The confusion is common and dangerous. Pareto's 80/20 says 80% of results come from 20% of inputs — applied to marketing, this might suggest you focus exclusively on your highest-converting 5% and ignore the rest. The 95:5 rule argues the exact opposite: all revenue comes from the 5% in-market at any given time, but that population rotates — today's 95% become tomorrow's buyers. Ignoring the out-of-market majority doesn't eliminate them; it just ensures you're not on their shortlist when they're finally ready.
At what stage should a B2B startup start investing in brand building?
Earlier than you think. The compounding nature of brand recall means the founders who plant flags in year one are the ones who dominate shortlists in year three. That said, brand building before product-market fit is often premature — your category positioning, ICP, and value proposition need to be stable enough that what you're anchoring in memory is accurate. A practical heuristic: once you have 10-20 referenceable customers and a clear repeatable sales motion, start brand investment in parallel with activation — not after it.
What's the difference between brand building and demand generation — and which should I prioritize?
Demand gen captures existing intent (the 5%). Brand building creates future intent (the 95%). Both are required — the question is sequencing and proportion. Most founders default to demand gen first because it produces measurable pipeline. The trap is that demand gen without brand building eventually hits a ceiling — you're fishing the same in-market pond over and over while the wider market has never heard of you. Binet & Field recommend roughly equal investment once you reach scale; earlier-stage founders can weight demand gen heavier (60-70%) but should never drop brand to zero.
How do B2B buyers actually form mental shortlists — and how do I get on them?
Mental shortlists are built through repeated, low-intensity exposure over time — not through one brilliant campaign. Buyers passively accumulate brand familiarity through category content, peer recommendations, industry events, founder visibility, and even ads they don't consciously register. To get on shortlists: own a clear and distinct position in your category, show up consistently in the channels where your buyers spend passive time (LinkedIn, newsletters, podcasts, industry communities), and link your brand to the specific buying triggers (category entry points) that are most common in your space.
Is the 95:5 rule a fixed ratio or does it vary by industry?
It's a mental model, not a hard law. Professor John Dawes derived the 5% figure from the observation that B2B companies switch vendors roughly once every five years — meaning ~20% are in-market annually and ~5% per quarter. But Forrester's own analysis found that B2B marketing technology vendors may have 15-30% of their audience in-market at any given time, depending on category maturity and deal cycle length. The implication is always the same: run your own calculation using your average contract length, but assume the out-of-market majority is larger than your activation campaigns are accounting for.
Does the 95:5 rule apply to B2C or is it only relevant for B2B?
The rule originated in B2B marketing because long repurchase cycles make the in-market/out-of-market gap especially stark — but the underlying principle applies to any category with infrequent purchases. B2C categories with short buying cycles (FMCG, food, fashion) have a much higher percentage of in-market buyers at any given time, making brand recall less critical to individual transaction outcomes but still essential at scale. For founders in B2B SaaS, professional services, or enterprise software, the ratio is most directly applicable and consequential.
What is 'mental availability' and how does it relate to the 95:5 rule?
Mental availability — a concept from Professor Byron Sharp's How Brands Grow — is the probability that your brand comes to mind when a buyer encounters a relevant buying situation. It's the mechanism through which the 95:5 rule operates: brand building during the out-of-market phase builds mental availability so that you surface naturally when buyers finally flip into the 5%. Sharp's research shows that mentally available brands are selected disproportionately often — not because buyers make rational comparisons, but because they default to what's already in memory. For B2B startups, this means winning deals starts long before the deal exists.
How does the 95:5 rule change how I should think about my content marketing strategy?
Most startup content strategies are built entirely for in-market buyers — product comparisons, case studies, ROI calculators, demo CTAs. These are activation assets. They convert the 5% who are already looking. Brand-building content serves the 95% who aren't ready yet — and it looks different: it educates your category, names problems buyers haven't articulated yet, shares a point of view, and builds trust over time. A healthy B2B content mix includes both layers: top-of-funnel content that reaches the out-of-market majority (category education, thought leadership, founder perspective) and bottom-funnel content that converts them when they arrive (comparisons, testimonials, demos).
Why does cold outbound get harder the longer I rely on it as my only channel?
Cold outbound is a pure activation play — it only reaches the 5% in-market at the time of contact, and even then, it relies on timing luck rather than brand preference. Founders who rely exclusively on outbound eventually hit a wall: response rates decay, sequences get ignored, and every deal feels like starting from zero. The underlying problem is that your brand has no gravity — prospects don't recognize your name, don't have prior context, and have no reason to respond. Brand building creates the 'warm' layer that makes outbound dramatically more effective: when a buyer has seen your content for months before getting your cold email, it's no longer cold.
What's Mark Ritson's 'two-speed marketing' approach and how does it apply to startup GTM?
Ritson's two-speed marketing is a practical framework for running brand building and sales activation simultaneously rather than treating them as competing priorities. Speed one is long-term: broad-reach, emotion-led, brand-building campaigns targeting the entire category — including the 95% out-of-market. Speed two is short-term: targeted, rational, conversion-focused activation campaigns aimed at the 5% in-market right now. For startup founders, this maps directly to GTM: don't wait until you've 'finished' building brand equity to run activation, and don't pause brand investment when pipeline pressure spikes. Run both engines in parallel at the ratio that matches your stage.
