P3-20 Cohort Analytics Dashboard
Retention curves, activation funnels, and cohort comparison — built on PostHog data.
Scoring Card
Section titled “Scoring Card”| Dimension | Score | Rationale |
|---|---|---|
| Pain | 3/5 | Data exists in PostHog but building actionable dashboards requires expertise |
| Revenue | 3/5 | Justifies higher-tier pricing for data-driven teams |
| Build | 3/5 | Pre-built dashboards on top of PostHog HogQL — moderate effort |
| Moat | 3/5 | Integration with GrowthOS segments and attribution creates unique views |
| Total | 12/20 |
Classification
Section titled “Classification”The Pain It Kills
Section titled “The Pain It Kills”“We have PostHog set up but nobody on the team knows how to build a retention matrix. We just look at daily active users and hope for the best.”
- PostHog and Mixpanel have raw analytics power, but building actionable growth dashboards requires a dedicated analyst.
- Amplitude charges $49K+/yr for advanced cohort analysis features.
- Most teams never build retention matrices, activation funnels, or channel performance views — they lack the expertise.
- Growth-specific views (activation by referral source, retention by onboarding completion) require joining data across multiple systems.
What It Does
Section titled “What It Does”- Retention matrix — classic cohort retention table showing week-over-week or month-over-month retention by signup cohort.
- Activation funnel — pre-built funnel showing signup → key activation events → conversion, filterable by segment.
- Cohort comparison — compare retention and activation rates across any two segments or time periods.
- Channel performance — which acquisition channels (from UTM Attribution) produce the highest-retention users.
- Exportable reports — PNG, CSV, and scheduled email delivery of key dashboards.
All built on PostHog’s HogQL query engine, using GrowthOS segment definitions for cohort slicing.
Competition & What We Replace
Section titled “Competition & What We Replace”| Tool | Pricing | Limitation |
|---|---|---|
| PostHog | Free-$450+/mo | Has raw capability but requires building dashboards from scratch |
| Amplitude | $49K+/yr (advanced) | Expensive, separate tool with no growth module integration |
| Mixpanel | $20-833/mo | Analytics-only, no connection to growth actions |
GrowthOS cohort analytics is pre-built and pre-connected. Segments, attribution, and contact data are already there — no data engineering required.
Moat & Defensibility
Section titled “Moat & Defensibility”Pre-built + pre-connected (3/5).
- Cohort definitions come from the Segment Builder — no need to recreate audiences in an analytics tool.
- Channel data comes from UTM Attribution — first-touch and multi-touch models already computed.
- Growth-specific dashboards (referral cohort retention, onboarding completion correlation) are unique to GrowthOS.
Interoperability Advantage
Section titled “Interoperability Advantage”What Ships
Section titled “What Ships”- Retention matrix — week/month cohorts, configurable retention events
- Activation funnel — multi-step with segment filtering
- Cohort comparison — side-by-side any two cohorts or time periods
- Channel performance view — retention and activation by acquisition source
- Exportable reports — PNG, CSV, scheduled email delivery
What Does NOT Ship
Section titled “What Does NOT Ship”- Custom SQL queries (use PostHog directly for ad-hoc analysis)
- Predictive analytics or ML-based forecasting (Phase 4 consideration)
- Real-time streaming dashboards (dashboards refresh on configurable intervals)
- Custom visualization types beyond pre-built templates
Build vs Buy
Section titled “Build vs Buy”BUILD on PostHog.
Leverage PostHog’s HogQL engine for data queries. GrowthOS adds the pre-built dashboard layer, segment integration, and growth-specific views. No need to build an analytics engine from scratch.
Estimated effort: 4-5 weeks.
Dependencies
Section titled “Dependencies”| Dependency | Why |
|---|---|
| Segments (P2-06) | Cohort definitions for slicing retention and activation data. |
| UTM Attribution (P2-09) | Channel data for acquisition source performance views. |
| PostHog | Underlying event data and HogQL query engine. |
