How to Analyze Your Signup Funnel in Postgres — Without Writing SQL
Every step of your signup funnel — visits, account creation, email verification, first key action — is already recorded somewhere in your Postgres database. But assembling those tables into an actual funnel means multi-step joins, cohort windows, and timestamptz alignment so a signup at midnight UTC doesn't leak into the wrong day. If you're a founder or ops person without an analyst, these five questions build the funnel for you.
“What does our signup funnel look like from account creation to first key action, step by step?”
You can't fix a funnel you can't see. Laying out user counts and conversion rates at each step shows exactly where people fall out — and in a typical SaaS Postgres schema this crosses users, events, and onboarding tables in one query nobody enjoys writing by hand.
You get: A step-by-step funnel table with user counts, conversion rate per step, and the biggest drop-off highlighted.
“How many people signed up each week for the last 8 weeks, and is the trend up or down?”
Weekly signups are the pulse of top-of-funnel health, and weekly beats monthly because you spot changes three times faster. Grouping by week in Postgres correctly — respecting your timezone rather than the server's — is exactly the kind of detail worth delegating.
You get: A weekly signup count series with week-over-week change and the overall trend direction.
“What percentage of signups complete onboarding within their first day?”
Day-one activation is the strongest predictor of whether a signup becomes a real user. Measuring it means comparing each user's signup timestamp against their first meaningful action — a per-user time window that spreadsheets butcher and SQL handles cleanly.
You get: An activation percentage for day one, alongside 7-day and 30-day rates for comparison.
“Which signup source or campaign converts to activated users at the highest rate?”
Raw signup counts flatter high-volume channels; activation rates reveal quality. If organic search signups activate at twice the rate of a paid channel, your budget conversation just changed. This joins your attribution columns to behavioral events — worth asking, painful to write.
You get: A table of signup sources ranked by activation rate with volume for each.
“Where in the funnel do users stall the longest before their next step?”
Drop-off tells you where people quit; time-in-step tells you where they struggle. If users take three days between verifying email and creating their first project, that gap is your onboarding's weakest moment — and probably a one-email fix.
You get: A table of median time between each funnel step, flagging the slowest transition.

Frequently asked questions
Do I need SQL or an analytics tool to build this funnel?
Neither. You ask the questions above in plain English against your existing Postgres database. The AI writes the multi-step SQL, runs it read-only, and returns the funnel as a table or chart you can interrogate with follow-ups.
Is it safe to connect the production database that holds our user data?
Yes — connections are read-only by default, so user records are never modified. A dedicated SELECT-only Postgres role, or a read replica if you have one, adds another layer of comfort.
We never defined funnel steps formally — events are just rows in an events table. Can it still build a funnel?
Yes. Describe the steps in your question ("signed up, verified email, connected a database, ran a query") and the AI maps them to your event names, in order, with per-user deduplication. You can rename or reorder steps in a follow-up question.
