Executive Summary

StreamSphere is a product case study for a YouTube-inspired video platform focused on improving user retention and engagement. Through user problem discovery and opportunity mapping, I identified poor Day-7 retention and fragmented viewing continuity as the primary challenges. The solution introduces Personalized Recommendations and Continue Watching, supported by a complete product strategy including PRD, roadmap, KPI framework, analytics instrumentation, and Mixpanel dashboards to measure business impact.

Problem

Strong acquisition but weak Day-7 retention, indicating users consume content without forming a long-term habit.
Users frequently abandon videos and struggle to resume unfinished content across sessions.
Low engagement with recommended content limits watch time, session depth, and creator interactions.

Solution

Personalized Recommendations

Surface context-aware video recommendations near the end of long-form content to encourage continuous viewing, improve content discovery, and increase session duration.

Continue Watching

Help users seamlessly resume partially watched videos from the home screen, reducing friction and improving returning-user engagement.

Product Reflection

Building StreamSphere reinforced that effective product management starts with solving the right user problem before expanding feature scope. Rather than introducing multiple engagement features, I focused on Personalized Recommendations and Continue Watching to address the primary drivers of low user retention.

Through this project, I applied product frameworks such as MoSCoW Prioritization, roadmap planning, and analytics strategy to balance user value, business goals, and implementation effort. Defining KPIs, event taxonomy, and success metrics also strengthened my understanding of measuring product outcomes, not just feature delivery.

This experience deepened my understanding of end-to-end product thinking — from problem discovery and prioritization to execution planning and data-driven decision making.

Future Scope

Future iterations of StreamSphere would focus on validating the MVP and expanding engagement based on user behavior and analytics.

Potential roadmap initiatives:

AI-powered personalized recommendation feed
Bell notifications for creator uploads
Smarter homepage content ranking
AI support bot to help users navigate to the content they want.

Future enhancements will be prioritized based on user feedback, experimentation results, and business impact.
