Case Study: Rosetta Stone doubles retention, lesson completion, and subscriptions with Amplitude

How Rosetta Stone used data to transform its approach to teaching and learning, driving engagement and revenue in the process

Rosetta Stone, the long‑standing leader in technology‑based language learning, faced mounting competition and mounting user complaints that its signature immersion method wasn’t working for everyone — about 5% of 2018 feature requests asked for translations. The company needed a data‑centric way to test whether offering translations would improve engagement, retention and sales.

Using Amplitude (Segmentation, Funnels), Rosetta Stone A/B tested an on‑demand translation feature in its Spanish module, built version‑specific dashboards, and iterated quickly. Learners who used Translations completed foundational exercises at 2x the rate, doubled day‑7 retention, and bought more than twice as many subscriptions, driving hundreds of thousands in additional revenue and prompting a company‑wide shift to data‑driven product decisions.
