Cohort and Retention Intelligence Without an Analytics Engineer

A growth team got live cohort retention and revenue-at-risk tracking across three disconnected systems — in 3 weeks, without a data engineering ticket.

Multi-channel e-commerce, weekly live cohort refresh, zero data engineering tickets.

The Situation

A mid-market e-commerce operator had transactional data in their database, customer attribute and acquisition data in a marketing platform export, and subscription/renewal event data in a separate system. The growth team needed weekly cohort retention rates, revenue-at-risk from churning segments, and acquisition channel attribution — all cross-source. The analytics engineering backlog meant these reports were built once and never maintained. Decisions on acquisition budget allocation were being made from data that was 30–60 days stale.

Acquisition budget was being spent against a picture of the business that was up to two months old.

What Was Breaking

Why manual operations couldn't scale

01

Retention math required three systems that never lined up.

Transactions, acquisition and attribution data, and subscription events lived in three places with no shared pipeline connecting them.

02

Reports were built once and abandoned.

Each cross-source question competed with the analytics engineering backlog — by the time a report shipped, the business question behind it had usually already shifted.

03

Budget decisions ran 30–60 days behind reality.

A channel whose retention had quietly collapsed a month ago could still be receiving budget today, because nothing was flagging the drop.

The approach

The Approach

1

Connect your sources

Transactional DB, marketing export, and subscription system connected read-only — no engineering ticket.

2

Configure cohort rules in plain English

Retention windows, attribution logic, churn thresholds — written by the growth lead, validated by Autonmis.

3

Autonmis runs the pipeline weekly

Cohort construction, retention calculation, and dashboard publish run automatically. Query anytime on demand.

Weekly Cohort Dashboard
Revenue-at-Risk Alerts
Growth Self-Serve Queries

Connected to all three sources. The Knowledge Base was configured with cohort definitions, retention window rules, revenue attribution logic, and churn threshold definitions — written in plain English by the growth lead, validated against the schema by Autonmis. A multi-step pipeline ran weekly: source refresh, cohort construction, retention calculation, revenue-at-risk roll-up, dashboard publish. The growth lead could ask Autonmis "which acquisition channel has the worst 90-day retention in the last three cohorts?" and receive a grounded, SQL-executed answer with the underlying data visible and auditable. No ticket to data engineering. No waiting for the next sprint.

The Workflow

TriggerWeekly pipeline run, plus on-demand query from the growth lead at any time.
Data SourcesTransactional database · Marketing platform export (acquisition/attribution) · Subscription system (renewal/churn events)
Runs AsA governed weekly pipeline (source refresh → cohort construction → retention calculation → revenue-at-risk roll-up → dashboard publish); ad-hoc questions answered directly against the same grounded definitions, with the underlying SQL visible.
Human in the LoopGrowth lead defines and validates cohort, retention-window, and churn-threshold rules directly in the Knowledge Base — no engineering ticket — and reviews revenue-at-risk alerts before reallocating acquisition budget.

Results

30–60 days stale → weekly refresh

Data freshness for retention analysis

Same-day refresh available on demand

Audited against the analytics-engineering-backlog cadence measured before connection.

Zero

Engineering tickets required after initial setup

Growth lead runs queries and pipeline independently

Confirmed across the period since go-live.

Live from week 3

Growth team self-serve query capability

Cross-source questions answered with auditable SQL

22 days

Time to first live cohort dashboard

From disconnected sources to production intelligence

Eliminated

Decisions made from stale data

Acquisition budget now allocated on current cohort data

Governance Note

The growth lead's cohort and churn definitions live in the Knowledge Base, not in one analyst's spreadsheet formulas — so 'which channel has the worst 90-day retention' gets the same validated answer whether it's asked in week one or week twenty.
