Funnels and Cohorts: Find Where the Money Leaks

Traffic tells you people showed up. Funnels tell you where they left, and cohorts tell you whether you are getting better at keeping them. Datalenk gives you both, tied to revenue and to where customers came from, without a data team.

What it does

• Conversion funnels: define an ordered sequence (landing → signup → activation → payment) and see the drop-off at each step. The fastest way to find where revenue leaks.
• Cohort retention: group customers by signup period and track each over time, so you can read down the columns and see whether your newest cohorts retain better than your oldest.
• Segmented by source: split funnels and cohorts by acquisition channel, so you learn not just where you leak, but which channels bring customers who stick.
• In revenue, not just counts: funnels and cohorts report revenue retention, not only headcount, because a cohort that keeps few but high-value customers is a different story than one that keeps many cheap ones.

How it works

1. Add the script and connect Stripe so lifetime events (upgrades, churn) flow in.
2. Define your funnel steps from pageviews and custom events.
3. Read the funnel for leaks and the cohort triangle for trend. Both segmentable by channel, campaign and link.

Why this matters

Most analytics either has no funnels or locks them behind a higher tier (Plausible puts funnels on its Business plan). And almost none tie cohorts to acquisition source, which is the combination that tells you where to fix onboarding and which channels to scale. Reading down a cohort column, not across a row, is where the real signal lives: it shows whether your product is getting stickier, cohort over cohort.

FAQ

What is funnel analysis? Measuring drop-off across an ordered sequence of steps, so you find the exact point where prospects leave before converting or paying.

How are cohorts useful for a founder? They show whether your newest customers retain better than your older ones (product getting stickier) and which channels bring loyal versus churning customers, so you fix onboarding and fund the right channels.

Do funnels cost extra? No. Funnels and cohorts are part of the product, not a higher-tier upsell.
