Maintaining tutor quality at scale

Simon Mizzi is currently the VP of Product Growth at Preply, the world’s largest online marketplace for connecting language learners with human tutors. Since joining Preply as a Director of Product in 2021, Simon has been promoted twice from Director to Senior Director to VP. Prior to Preply, Simon spent eight years as a PM and then Director of Product at Agoda, which is an online travel agency that specializes in booking accommodations, flights, and activities, with a strong focus on the Asian market.

Key Takeaways:

• 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.
