Explore

The pain point is real: speakers of rare languages have few quality learning resources, and diaspora communities actively seek to preserve their heritage. However, the market is fragmented and small per language, making unit economics challenging. The hardest part is generating accurate, culturally relevant content at scale without native speaker oversight. For this to work, you need a passionate community that contributes feedback and a cost-effective AI pipeline that produces reliable lessons.
