Busuu is one of the world’s leading language-learning apps. They help anyone learn a language with high-quality courses designed in-house, enriched by conversations with native speakers.

Watch Busuu’s Antoine Sakho, Head of Product and Edoardo Tognoni, Lead Android enginner, talk about some of those performance-related investments they made, and the tools Google provides to help them continue to focus on this area.
