Help teams transform from intuition-based to data-informed decision-making through proven methodologies and best practices.

Core Capabilities

1. Analytics Framework Design

Guide the selection and implementation of appropriate analytics approaches based on business maturity and objectives:

Four Analytics Types:
- Descriptive Analytics: Understanding what happened through historical data analysis
- Diagnostic Analytics: Identifying why specific patterns occurred
- Predictive Analytics: Forecasting future behaviors using ML and statistical models
- Prescriptive Analytics: Recommending specific actions based on predictions

When to use each:
- Start with descriptive analytics to establish baselines and understand current state
- Add diagnostic analytics when patterns need explanation
- Implement predictive analytics once sufficient historical data exists (typically 6+ months)
- Deploy prescriptive analytics when organization can act on automated recommendations

Deliverables to help create:
- Analytics maturity assessment
- Phased implementation roadmap
- Framework selection recommendations
- Tool and platform requirements

2. North Star Metric Definition

Help identify and validate the single metric that captures core product value:

Definition Process:
1. Identify Core Value: What fundamental value does the product deliver to users?
2. Find Measurable Proxy: Which metric best represents this value?
3. Validate Leading Indicator: Does this metric predict long-term success?
4. Ensure Actionability: Can the team influence this metric through product decisions?

Industry Examples for Inspiration:
- Spotify: "Time spent listening"
- Airbnb: "Nights booked"
- Netflix: "Hours watched"
- Duolingo: "Daily active learners"

Common Pitfalls to Avoid:
- Choosing vanity metrics disconnected from business value
- Selecting lagging indicators that don't inform daily decisions
- Picking metrics the team cannot influence
- Defining multiple "North Star" metrics that dilute focus

3. Cohort Analysis Implementation

Design and implement cohort analysis strategies to understand user behavior patterns over time:

Cohort Types:

Acquisition Cohorts (group by signup date):
- Perfect for tracking retention trends
- Compare marketing campaign effectiveness
- Analyze seasonal patterns
- Measure product improvements across time

Behavioral Cohorts (group by specific actions):
- Identify what drives retention vs churn
- Understand feature impact on engagement
- Optimize onboarding effectiveness
- Measure activation patterns

Implementation Steps:
1. Define cohort criteria clearly and consistently
2. Choose appropriate analysis timeframes (Day 1, 7, 30, 90)
3. Select relevant metrics (retention, revenue, engagement, feature usage)
4. Build comparison framework to identify trends
5. Create actionable insights from patterns
6. Iterate based on findings

Critical Questions to Answer:
- When does churn typically occur and why?
- Which acquisition sources bring most valuable users?
- How do different user groups behave over their lifecycle?
- What activation patterns predict long-term retention?

4. User Segmentation Strategy

Design segmentation approaches for personalized experiences at scale:

Segmentation Types:

Demographic Segmentation:
- Age, gender, language, location
- Best for: Localization and basic targeting

Behavioral Segmentation:
- Login frequency, features used, journey stage
- Best for: Experience optimization and personalization

Psychographic Segmentation:
- Interests, values, lifestyle, motivations
- Best for: Messaging and emotional resonance

Technographic Segmentation:
- Device type, OS version, browser
- Best for: Technical optimization and compatibility

Segmentation Best Practices:
- Start with 3-5 key segments, expand as needed
- Ensure segments are mutually exclusive and collectively exhaustive
- Make segments actionable with different strategies per segment
- Update segmentation as product and user base evolve
- Validate segment differences with statistical testing

Benefits:
- Increased user activation
- Faster time-to-value
- Optimized in-app communication
- Higher conversion rates
- Better product-market fit

5. Product-Led Growth (PLG) Strategy

Design PLG approaches where the product itself drives acquisition, conversion, and expansion:

Core PLG Principles:

Contextual Onboarding:
