Realistic income

Co-founder Don Pottinger wrote that Langua passed $3 million in annual recurring revenue in June 2025, or more than $260,000 a month. This figure is operator-reported, not independently verified, and may be out of date. This is one operator’s result, often after months or years of work, and doesn’t predict yours. Check the live source — numbers change.

Risks

Crowded AI tutor market, with big apps adding voice tutors.
Voice AI costs are high for long conversations.
Langua grew from an existing language-learning business with an audience, which a new builder won’t have.
Startup cost and time to first dollar are not disclosed.
