Preply was founded in Kyiv, Ukraine as a tutor matching marketplace that uses machine learning to increase the efficiency of pairing students with language tutors around the world. After this early success, Preply decided to build a full online language learning platform, integrating tutor matching with a virtual classroom for live one-on-one lessons.
Video and audio quality are extremely important to Preply’s revenue, retention, and overall customer success. That means a lot of thought went into the decision to choose the right partner for real-time audio and video. After rigorously testing a number of solutions, Preply found that Agora’s real-time engagement platform offered the highest quality audio and video experience for students and tutors.
After implementing Agora, Preply saw a huge improvement in the quality of video lessons—proven by customers’ usage metrics. Additionally, with Agora’s excellent customer support, Preply was able to improve the success rate of each lesson by up to 18%.
“We chose Agora because they offer the highest quality real-time audio and video in addition to the best customer support. Agora is essential to helping Preply improve our most important metric for online learning—lesson success rate.”
