Case Study: The League boosts installs 30% and doubles engagement with Branch (branch.io)

The League gets install boost and higher engagement by implementing a mobile referral program and waitlist using branch.io

The League, a selective dating app launched in 2014, used an invite-only waitlist to create exclusivity but needed a mobile-native referral system to let users move up the list by getting friends to install. The main challenge was attributing mobile installs to the referring user and running a seamless, code-free referral flow.

By integrating Branch’s contextual deep links and referral backend, The League generated unique referral links, routed installs to the correct post-install experience (waitlist or bypass), and automatically credited referrers—implemented in just hours. The program drove a 30% lift in installs from referrals, a 31% higher signup conversion for referred users, and doubled engagement for those users; CTO Derrick Staten reported the integration took under 30 minutes.
