Funnels

A funnel is an ordered list of events with a time limit. Vertex counts every user who completed step one and shows where the rest fell out.

Define the steps

Create a funnel from any two or more tracked events. Steps must happen in order for a user to count as converted, but other events in between are fine — a user who wanders off to the docs and comes back still converts.

Starter workspaces can keep 3 funnels; Growth and Scale are unlimited.

json

{
  "name": "Visit → Trial → Paid",
  "steps": ["page-view", "trial-started", "invoice-paid"],
  "windowDays": 14
}

Conversion windows

The window is how long a user has to finish the funnel after step one. The default is 7 days; b2b products with long evaluation cycles usually want 30 or 90.

Changing the window recomputes the funnel from history — no re-tracking needed. Note that history itself is bounded by your plan's retention: 30 days on Starter, 12 months on Growth, unlimited on Scale.

Reading the chart

Each bar shows the share of step-one users who reached that step. The steepest drop is your best place to intervene — a 60% fall between 'trial-started' and 'invoice-paid' says more about pricing than any survey.

Hover any bar to see absolute counts and the median time users took to arrive there.

Segment comparison

Split any funnel by a property — plan, referrer, country — to compare cohorts side by side. If the 'lorem-newsletter' referrer converts at twice the rate of paid ads, your budget conversation writes itself.
