How Preply Built the World’s Largest Language Learning Marketplace

In this episode

• Preply has built the world’s largest language learning marketplace, with an online platform that connects over 100,000 experienced tutors teaching dozens of different languages to millions of learners across the globe.
• Preply’s human-powered marketplace differentiates it from language learning apps like Duolingo and Babbel that are 100% digital. While scaling to 100,000+ tutors has been difficult, it has also helped Preply boost learner motivation, increase subscriber retention, and ultimately improve learning outcomes.
• Preply has run hundreds of experiments to optimize its learner onboarding flow, improve its tutor matching algorithm, and accelerate time to value. While these experiments have improved registration, activation, and trial lesson start rates, ultimately Preply focuses on subscriber conversion and retention as the metrics that matter most, because subscriptions are what drive value for the business.
• In parallel, Preply has invested heavily in maintaining tutor quality as it scales the supply side of its business. This includes surfacing metadata about tutors that build confidence for new learners, as well as imposing policies that encourage tutors to maximize their availability so that learners have a positive experience.
• While Simon believes language learning is an inherently human activity that will never be fully replaced by technology, he is excited about the potential for AI to boost tutor productivity and hyperpersonalize the language learning experience.
