Our take
Babbel is one of the leading lights in the language eLearning sector. Its premium subscription-based online learning resources cover over a dozen predominantly European languages, at all proficiency levels. They include interactive lessons and podcasts - all developed and delivered by professional educators and linguists.
Learning languages online has become big business in recent years, and this has led to a surge of VC investment in the sector. This diversified the field of competition, tripling revenue for smaller rivals like Busuu and driving up engagement on online tutoring sites. It has ramped up pressure on incumbents like Babbel, and its better established (but pricier) competitor Rosetta Stone, to diversify their offerings.
To get there, Babbel has taken a smart cue from live tutoring sites like Preply, which also saw a surge in engagement over recent years. Babbel has launched its own live tuition offering, and additional B2B services, demonstrating a savvy use of its leading position and strong resources to keep a tight grip on its substantial market share.
