Case Study: Yousician achieves consistent full-stack experimentation at scale with Unleash

Yousician runs 600+ experiments with Unleash

Yousician, a music learning platform with over 25 million monthly active users, faced challenges with its A/B testing. Their initial tools caused inconsistent experiments across different devices and platforms, which reduced trust in the results. They needed a more robust solution to run reliable, full-stack experiments. To address this, Yousician adopted Unleash Enterprise from the vendor Unleash.

The solution from Unleash enabled Yousician to run experiments consistently across its entire tech stack using server-side targeting. This allowed data scientists to analyze results using their own data warehouse and business metrics like customer lifetime value. By implementing Unleash, Yousician successfully ran over 600 experiments, created 516 feature flags, and embedded a culture of data-driven decision making, leading to faster and more confident feature releases.
