Cohort Retention Audit (Flagship Engagement)

Executive Overview

The Cohort Retention Audit is our core analytical engagement designed for mobile and web product teams that need objective clarity on why registered users abandon their application. Rather than examining surface-level dashboard summaries, our senior analysts query raw event tracking logs to reconstruct your actual cohort degradation curves from Day 0 through Day 90.

This audit isolates friction points in the initial onboarding flow, validates whether critical lifecycle telemetry is recording accurately, and determines your product’s genuine natural usage frequency.

Target Audience & Application Profile

This engagement is structured specifically for:

• Growth-Stage Mobile Applications: Native iOS and Android products experiencing high customer acquisition costs with steep Day-1 or Day-7 retention drop-offs.
• Subscription Web Platforms: Web apps with recurring usage models where early user dormancy leads to unpreventable renewal cancellations.
• Engineering & Data Teams Planning Redesigns: Product organizations that need clean baseline telemetry and verified behavioral retention drivers before altering core features.

3-Week Engagement Stages & Delivery Schedule

Week 1: Telemetry Hygiene & Data Verification
├── Ingest raw event streams and schema dictionaries
├── Validate session boundary definitions and client payload schemas
└── Detect dropped events, duplicate logs, and anonymous-to-identified tracking gaps

Week 2: Cohort Modeling & Behavioral Segmentation
├── Construct N-day, bracketed, and unbounded retention curves
├── Identify behavioral clusters separating retained power users from churned users
└── Map activation milestones and quantify time-to-first-value (TTFV)

Week 3: Diagnostic Synthesis & Engineering Roadmap
├── Deliver Executive Findings Briefing (60-minute video presentation)
├── Supply granular engineering tickets for telemetry remediation
└── Deliver the Prioritized Retention Intervention Blueprint

What Is Included in the Scope

1. Raw Telemetry & Schema Verification: Line-by-line audit of your top 50 event definitions, client-side payload properties, and tracking accuracy across iOS, Android, and Web platforms.
2. Mathematical Cohort Decomposition: Calculation of True Day-1, Day-3, Day-7, Day-14, Day-30, and Day-60 retention metrics segmented by acquisition source, device model, and user persona.
3. Activation Milestone Identification: Statistical correlation analysis identifying which early behavioral actions (“Aha moments”) produce a permanent uplift in lifetime retention.
4. Natural Frequency Matrix: Empirical determination of whether your application naturally operates on a daily, weekly, or monthly usage cadence, preventing harmful notification over-saturation.
5. Detailed Remediation Documentation: Complete Markdown and PDF report containing annotated charts, code-level event payload corrections, and lifecycle re-engagement specifications.
6. Live Advisory Presentation: A 60-minute interactive workshop with your product, engineering, and data teams to discuss findings and implementation priorities.

What Is Excluded

• Scope is dedicated strictly to analytics, data architecture, and retention strategy; client engineering teams retain full control over production codebase commits.
• Growth and lifecycle strategy focuses on product retention analytics rather than paid acquisition media buying.
• All generated analytical models, queries, and reports become the permanent property of your organization.

Client Preparation & Prerequisites

To begin the Cohort Retention Audit, your team will need to provide:

• Standard mutual Non-Disclosure Agreement (NDA) execution.
• Read-only query access to your event data warehouse (e.g., BigQuery, Snowflake, PostgreSQL) or analytics provider (e.g., Amplitude, Mixpanel, PostHog, Segment).
• Your current event tracking dictionary or schema documentation.
• A 45-minute kickoff interview with your lead product manager and data engineer.

Engagement Pricing & Next Step

The Cohort Retention Audit is billed as a fixed-fee advisory engagement of $7,800 USD (or local Thai Baht equivalent). Payment is split into a 50% initial mobilization deposit and 50% upon delivery of the final synthesis and executive briefing.
