Our take
Preply stands as a global hub for language learning, distinguished by its emphasis on real-time tutor interaction. Through its user-friendly interface, Preply connects students with skilled tutors worldwide, facilitating flexible lessons from the convenience of their homes.
In recent years, there has been a notable upsurge in individuals seeking to master new languages, a trend projected to propel the market to a staggering $47B by 2025. While competitors like Duolingo, Babbel, and Busuu also want a share of this market, Preplyu's nice lies in its live instruction and diverse pool of native teachers, setting it apart from gamified, self-directed platforms.
With over 15M lessons booked to date and a network of more than 32,000 tutors spanning 175 countries, Preply has established itself as a frontrunner in the language learning space. Looking ahead, Preply is strategically positioning itself for continued growth, particularly in bolstering its B2b offerings and expanding its business development initiatives.
