Who we are
📱 Yubo is a safe space for young people to socialize and make connections while streaming and chatting online through an app.
🔒 The platform boasts an innovative suite of safety tools that guarantee all its users’ security, moderation, and privacy.
Faced with a new generation of hyperconnected digital natives who are lonely and overwhelmed, Yubo helps Gen Z engage with the world and learn about themselves. Inspired by the best of offline interactions and the possibilities of digital life, Yubo's vision is to fix online social interactions for the next generation. Unlike traditional social networks, Yubo prioritizes people over content, real-time interactions over likes, and real connections over followers.
🌍Created by three friends/engineers who are passionate about consumer apps and thanks to a team of 60 people in 3 different offices (Paris, Londres, Jacksonville), Yubo now has 50 million users across and attracts approximately 2 million new users every day.
Since its launch in 2015, the app’s users have:
✔️made more than 2 billion real connexions/friendships on the platform.
✔️ sent more than 10 billion chat messages.
✔️ streamed live almost 30 million times.
Within the Performance team and in close collaboration with the Yubo mobile and live team you will be in charge of improving the overall performance of the application (instant app startup, APK size reduction, memory footprint reduction, CPU and GPU usage reduction, bandwidth reduction), evangelizing on code and architecture best practices.
