THE SHORT ANSWER
Measure GTM with a small set of linked metrics suited to the motion: qualified demand or pipeline, conversion, sales-cycle time, acquisition cost, activation, retention or churn, revenue, customer value, payback and referral. Define each metric, segment it appropriately and connect it to a decision. Avoid universal benchmarks detached from model and stage.
Measure the chain
| Layer | Example evidence | Decision |
|---|---|---|
| Reach | Suitable prospects reached | Audience and channel |
| Demand | Qualified leads or opportunities | Message and targeting |
| Conversion | Stage rates and sales cycle | Offer and buying path |
| Activation | First-value rate and time | Onboarding and customer fit |
| Retention | Continued use, renewal or repeat purchase | Product value and success |
| Economics | CAC, contribution, payback and customer value | Sustainability and scale |
| Advocacy | Qualified referrals or expansion | Value and trust |
Adapt metrics to the GTM motion
A sales-led company may emphasize qualified pipeline, stage conversion and cycle length. A self-service product may emphasize signup-to-activation and retained cohorts. A marketplace needs evidence from both sides. Definitions should match the decisions the team actually makes.
Connect acquisition to contribution
Customer acquisition cost is meaningful only with an explicit cost scope and customer count. LTV depends on retention, margin and forecast assumptions. Payback asks how long contribution takes to recover acquisition cost.
Use the Acquisition Cost Calculator, ROAS Calculator, Break-even Calculator and Gross Margin & Markup Calculator to test stated assumptions.
