Case Study: Kast achieves a 50% increase in user retention and better product decisions with Mixpanel

Kast uses Mixpanel to identify their power users and understand what leads to stickiness

Kast is a San Diego–based “virtual living room” that scaled rapidly during COVID-19 as millions used the platform for watch parties, game nights, and other social gatherings. As growth accelerated, the team struggled to make fact-based product decisions because they lacked a unified view of how users engaged with features, so many choices were made on gut instinct rather than data.

Kast implemented Mixpanel to track events, build cohorts, and run retention reports, enabling the team to identify power users, validate or discard feature hypotheses (e.g., discovering Push-to-Talk was widely used), and create metrics like “Churn 30.” The results were a shift to data-driven decision-making, faster, more focused feature development, a unified customer view and a 50% increase in user retention, plus better-informed product prioritization across the company.
