GTM funnel metrics

Track the funnel in the language of your motion. Early teams discover their true rates only by logging them. The useful trick is to work backwards from a customer goal to required top-of-funnel volume.

Pipeline — sum of open opportunity value (often weighted by stage probability). Rule of thumb for sales-led: maintain 3–4× pipeline coverage against the next period's quota.

Conversion rates by stage — lead → SQL → demo → proposal → closed-won.

Sales cycle length — median days from first qualified meeting (or trial start) to close. Stretching cycles destroy forecasts and raise CAC.

Win rate — closed-won / (won + lost) on qualified opps. Segment by ICP fit. A 40% win rate on ICP and 5% off-ICP means your problem is targeting, not demos.

CAC and payback — roll GTM spend into unit economics. Motion changes CAC structure more than any ad creative tweak.

Walking through 10 customers

Goal: 10 new customers next quarter. Historical rates: 20% of demos close, 50% of qualified conversations become demos, 10% of outbound replies become conversations, 5% of cold emails get replies.

Demos needed     = 10 / 0.20 = 50
Conversations    = 50 / 0.50 = 100
Replies needed   = 100 / 0.10 = 1,000
Emails to send   = 1,000 / 0.05 = 20,000

That backlog is the GTM plan. If you cannot send 20k personalized-enough emails, you need inbound, a tighter ICP, better reply rates — or a different motion.

Illustrative early-stage conversion (yours will differ — measure):

If proposal→won is 5%, the issue is often pricing, security blockers, or non-ICP — not prettier slides.

Common mistakes

• Flying blind on rates. Volume × conversion is the plan.
• Fat fictional pipeline with close dates that slip three times.
• Debugging demos when win rate is 40% on ICP and 5% off-ICP.

Check yourself

1. You need 10 customers, 20% of demos close. How many demos? 50.
2. Proposal→won is 5%. Where do you look first? Pricing, security, or non-ICP — not slide design.

Key takeaways

• Work backwards from the customer goal to top-of-funnel volume.
• Sales-led coverage rule of thumb: 3–4× pipeline against quota.
• Segment win rate by ICP. Targeting problems look like demo problems.
• If you cannot hit the volume, change ICP, rates, or motion.
