Case Study: CoLearn reaches 4M Indonesian students and accelerates experimentation with Optimizely Full Stack

CoLearn's AI homework app reaches 4M children in Indonesia

CoLearn is an Indonesian edtech founded in 2018 to teach STEM subjects and, during the pandemic, launched an AI-powered homework app and online classes to keep students learning. Faced with a sudden shift to fully digital delivery and unreliable internet for many users, CoLearn needed a way to optimize engagement and roll out new features without forcing frequent app updates or disrupting live classes.

By adopting Optimizely Full Stack for server-side experimentation, CoLearn ran staged rollouts and unlimited A/B tests, moving from ideation to launch in 15–30 days and safely introducing new subjects like physics. The approach let them deliver more content faster and at scale—reaching millions (4M+ students, about 1M weekly users), improving outcomes (80% grades improved), and boosting team productivity without harming performance.
