The customer is someone whose grandparents spoke a specific regional dialect that mainstream apps don't offer at all, searching in vain on major platforms before finding this one. Money is a revenue share with instructors who upload and sell their own dialect courses, plus a platform subscription fee for unlimited course access. The unmet-demand angle is the entire pitch to instructors too fluent speakers of an underserved dialect currently have zero monetization path anywhere else, which means a passionate native speaker becomes an eager, low-competition instructor the moment they're shown a real audience actually exists and is actively searching for exactly what they can teach.
