A GTM Without Numbers Is Not a Strategy

#

Government program reviewers spend an average of about three minutes reviewing each application, making an intuitive pass/fail judgment from the moment they read the opening summary. The most common trait of rejected plans is 'abstract vision-listing packed with trendy buzzwords and grand qualifiers but no real substance.' Writing 'social media ads, content marketing, B2B sales' in the GTM section is exactly this pattern.

A channel list is not a strategy — it's a menu of options. The sentence 'we'll promote through social media' answers none of the following: 'why this channel,' 'how much does it cost to acquire one customer through this channel,' or 'how is the initial three-month budget allocated.' The key to a winning plan is number-backed persuasion in a structure reviewers can read at a glance.

#

For a GTM to read as a 'strategy,' two things are needed: the reason for choosing a channel, and how money flows through it. The core GTM question is 'how do we reach customers, and does that become revenue?' Channels must be curated, not listed — and only channels where unit economics work should be scaled.

#

Breaking down budget by channel is not enough on its own. Reviewers are assessing whether you can manage money properly. Budget allocation must be grounded in assumptions. A figure like '₩5M for Instagram ads' carries little meaning on its own without a CAC assumption — that is, how many customers that budget is expected to acquire.

Bigger numbers aren't better — what matters is what assumptions they rest on. Assumptions such as monthly new customer count, average order value, and churn rate must be stated clearly so reviewers can follow the logic of your revenue projections. GTM channel budget → CAC assumption → projected customer acquisition → revenue estimate: when this chain breaks, revenue numbers become wishful thinking.

#

It's perfectly normal for early-stage founders to lack real measured CAC data by channel. The answer is not to hide your assumptions — it's to surface them. The principle of stating assumptions first in financial planning applies equally to how you describe GTM channel budgets.

1. Pick one channel and write one sentence explaining 'why this channel.' Use evidence such as where your target customers spend their time, or precedents from similar products.
2. State your assumption for how much it costs to acquire one customer through this channel. If you lack real data, label it an 'assumption' and cite your reference (comparable cases, industry estimates, etc.).
3. Break out the initial three-month budget by channel. Instead of 'marketing: ₩10M,' write 'Channel A: ₩5M, Channel B: ₩3M.'
4. Connect budget to CAC assumptions to calculate projected customer acquisition, and explicitly state that this figure feeds into your revenue estimate.

A GTM that honestly surfaces its assumptions shows reviewers 'how this team thinks about execution.' Clearly stated assumptions alongside numbers earn more trust than numbers without any rationale.
