Core concept: three models, one funding decision

Assuming the motions and the persistent buyer profilebuyer profileA semi-fictional, research-based representation of your ideal customer: their goals, frustrations, behaviours and decision criteria.View full definition → the foundations lesson sets out, the choice between them comes down to three models that feed each other:

• A sizing model: how many qualifying accounts exist, worth how much each, and what share is realistically winnable.
• A channel-fit score: which route reaches those accounts at a cost the price point can absorb.
• A funnel and payback model: how much cash sits between the first dollar of spend and the moment a customer has repaid it.

Run in that order, the models constrain each other. A segment worth $2 million in annual revenue cannot fund a field sales team no matter how good the deck is.

Unlike impressions, reach counts each person once, no matter how often they see it.View full definition → first value will not convert a self-serve funnel no matter how much traffic you buy.

Key sub-concept 1: bottom-up segment sizing

Top-down sizing ("1% of a $50 billion market") is unfalsifiable and therefore useless for a funding decision. Bottom-up sizing is falsifiable, which is the whole point.

Build it as a count, not a percentage: qualifying accounts × seats or units per account × annual price × the share you can realistically hold in five years.

Worked example. Filter a design tooling segment to companies with 200 to 2,000 employees, an in-house product team, and at least one paid design seat already in place. Say that filter returns 12,000 accounts. Fourteen editors each, at $144 per editor per year on an entry tier. That is 12,000 × 14 × 144, roughly $24 million if you won every account. Nobody wins every account. Apply a 10% ceiling for a contested category and the segment is worth about $2.4 million of ARR.

That single number ends arguments. Six account executives at a fully loaded $250,000 each cost $1.5 million a year before demand generationdemand generationMarketing activities designed to attract and capture contact information from prospects interested in your offer, creating a pipeline of potential customers.View full definition →. Against a $2.4 million ceiling, the motion is dead on the page.

The edge case that ruins most sizing sheets: land-and-expand. If the initial purchase is four editors and the account settles at fourteen over three years, first-year sizing understates the segment by a factor of three. Slack reported a net dollar retentionnet dollar retentionNet Revenue Retention measures the percentage of recurring revenue retained and grown from existing customers over a period, including upsell and expansion, net of downgrades and churn.View full definition → rate of 143% in the fiscal year before its 2019 listing; Figma has reported figures in the low 130s. At retention like that, cohort revenue roughly doubles in three years without a single new logo. Size the expansion curve, or you will underfund acquisition and then wonder why growth stalls two years later.

Key sub-concept 2: scoring channel fit instead of arguing about it

Score each candidate route on weighted criteria, 1 to 5, weights summing to 100. A workable rubric:

• Annual contract value against cost to serve (weight 25)
• Number of people who must say yes before money moves (20)
• Whether one user's usage creates pull for the next user (20)
• Time to first value with no human involved (20)
• Whether the buyer's search and community behaviour is findable and cheap (15)

The heuristics that anchor the ACV row are worth memorising. Below roughly $2,000 a year, only self-serve and marketing-driven acquisition clear their own cost. Between $5,000 and $25,000, inside sales and a hybrid land-then-call motion work. Above about $50,000 with five or more stakeholders, human selling is not optional.

The multiplayer row is where Slack and Figma score at the top of the scale and most B2B tools do not. A Slack message needs a recipient inside the same company; a Figma file link needs someone to open it. That structural pull is measurable: track invites sent per activated account in the first 14 days. If the number is below one, your product is single-player and the scorecard should say so, whatever the roadmap promises.

Failure mode to guard against: teams score the motion they have already staffed. Have the sales lead and the growth lead score independently before any headcount request. Any criterion where they differ by two points or more is the conversation that actually matters.

Key sub-concept 3: the funnel maths that picks the motion

Model both candidate motions on the same segment, same period, and compare CACCACCustomer Acquisition Cost (CAC) is the total sales and marketing spend divided by the number of new customers gained in a period. It measures how efficiently you grow.View full definition → payback: CAC ÷ (ACV × gross margin) × 12.

Self-serve version. 120,000 monthly visitors, 3.5% start a workspace (4,200), 22% activate on your defined activation event (924), 6% convert to paid within 90 days. That is about 55 paying teams a month at a $2,000 ACV, so $110,000 of new ARRARRAnnual Recurring Revenue (ARR) is the normalized, predictable revenue a subscription business expects to earn from active contracts over a single year.View full definition → a month against $90,000 of blended marketing and growth engineering spend. CAC is roughly $1,640. At 80% gross margin each team returns about $133 a month, so payback lands near 12 months.

Sales-led version, same segment. Six AEs fully loaded at $250,000 plus $600,000 of demand generation is $2.1 million. Twenty closed deals per AE per year at a $12,000 ACV gives $1.44 million of new ARR. Gross profit of $1.15 million against $2.1 million of cost is a payback of about 22 months. The motion is not wrong; the price point is. Take the same headcount into $30,000 deals and payback falls to roughly 9 months.

Two rules of thumb to apply on top. Payback under 12 months for volume segments, under 24 for enterprise. And the magic number (net new ARR in a quarter divided by the prior quarter's sales and marketing spend): above 0.75, pour money in; below 0.5, fix conversion before adding headcount.

The number that hides the damage is blended CAC. A self-serve motion at 8 months averaged with a new enterprise motion at 40 months produces a respectable-looking 19, and the board never sees that you are burning cash on every enterprise deal you sign. Report payback by segment and by motion, never as a single company-wide figure.

Key sub-concept 4: sensitivity, and what a free tier actually costs

Before funding anything, flex each input by a realistic amount and see which one moves the answer. In the self-serve model above, doubling traffic doubles the spend line alongside it and payback barely moves. Lifting activation from 22% to 30% takes monthly paying teams from 55 to about 75 at roughly flat cost, dropping CAC near $1,190 and payback to under 9 months. Activation and price are usually the sensitive inputs. Traffic almost never is.

The line most models omit is the cost of carrying non-payers. Support, storage and compute for free accounts is real cost of goods. At 400,000 free workspaces and $0.40 a month each, that is about $1.9 million a year sitting inside gross margin. If your payback model assumed 80% margin and the free tier drags blended margin to 68%, every payback figure in the sheet is understated by about a sixth. Model the free tier as an acquisition line item with its own cost per activated account, then judge it the way you would judge a paid channel.

Real-world cases

Case 1: slack's conversion maths

Slack's 2019 filing showed roughly 88,000 paid customers against more than 500,000 organisations on the free plan, so organisation-level paid conversion sat near 15%. A few hundred customers paying over $100,000 a year generated around 40% of revenue. Two lessons for the model. First, a self-serve funnel with double-digit conversion is exceptional, and if your sheet assumes it without the multiplayer pull Slack had (8,000 teams signed up in the first 24 hours of the August 2013 preview, because a message needs a recipient), the assumption is fiction. Second, the revenue concentration means the sizing model and the funnel model target different populations: self-serve seeds the account, human selling harvests it. Budget both or model neither.

Case 2: figma and the question of who counts as a seat

Sized against professional designers only, Figma's segment was small. Figma's own filings state that around two-thirds of its monthly active users are not designers, which is a sizing statement before it is a product statement: the seat count per account included developers, PMs and marketers, and pricing tiers were built to charge for viewing, commenting and dev handoff rather than editing alone. The financial consequence shows in the expansion figures, with 2024 revenue near $749 million growing close to 50%. Adobe's $20 billion agreement in September 2022, its collapse in December 2023 under EU and UK regulatory pressure, the $1 billion termination fee and the July 2025 NYSE listing are the outcome. The methodological point is narrower: change your definition of a seat and the same account list can be worth four times more.

Case 3: when the model says no

A product at $9,000 ACV with a six-person buying committee scores high on human selling and low on ACV support. Run the numbers: field sales cannot close enough $9,000 deals to clear a fully loaded rep, and self-serve cannot get six stakeholders to agree without one. The honest output is that neither motion is fundable at that price, and the decision moves to pricing or packaging, not to channel. Teams that skip the maths hire the reps anyway and discover this eighteen months later.

CMO action items

• Build the bottom-up sizing sheet with named account filters, and require that the account count comes from a real list you could export, not an analyst report.
• Run the channel-fit scorecard with two independent scorers before any headcount request, and treat every two-point gap as an agenda item.
• Instrument CAC payback by segment and by motion in your reporting, and ban blended CAC from the board deck.
• Fund the motion whose payback fits inside the cash you can finance, cap the second at 10 to 15% of budget, and write down in advance the metric that promotes it to full funding.

Common mistakes that kill gtm results

• Top-down sizing: "1% of a $50 billion market" cannot be proved wrong, so it cannot inform a decision. Count accounts.
• Modelling first-year ACV only: in a business with retention above 130%, this understates the segment badly and leads you to underspend on acquisition at exactly the point where spending is cheapest.
• Scoring channels after the hires: the rubric then rationalises a decision already made. Score first, in writing, with the date on it.
• Treating the free tier as free: it carries support and infrastructure cost that lands inside gross margin and quietly extends every payback figure in the model.
• Averaging payback across motions: one healthy motion will mask one that loses money on every deal, for as long as the mix holds.

Key takeaways

• Size bottom up: qualifying accounts × seats × price × realistic five-year share. A $2.4 million ceiling settles the field sales debate in one line.
• Score channel fit on weighted criteria, with ACV against cost to serve and multiplayer pull carrying the most weight. Invites sent per activated account in 14 days is the honest test of the second.
• CAC payback (CAC ÷ (ACV × gross margin) × 12) is the comparison metric across motions. Under 12 months for volume, under 24 for enterprise, and never blended.
• Activation rate and price move the answer; traffic mostly moves the cost line with it.
• Slack's roughly 15% free-to-paid conversion at organisation level with revenue concentrated in six-figure accounts, and Figma's two-thirds non-designer user base, both show the same thing: the definition of a seat and the definition of a converting account decide the size of the prize before any channel spend happens.
