Showing Friends' Event Plans Made Pie App Users Stay 5x Longer

In December 2025, Pie changed its app to show which of your friends were going to an event. Average time spent in the app jumped from 2 minutes to 10. The Chicago-based social app, founded by Bonobos co-founder Andy Dunn, has 300,000 users and $11.5 million raised. Seeing who you know — not finding events — kept people around.
