Startup concept

CourseDub

Sell a small, human-checked Spanish localization pack to course creators. Preserve teaching intent and terminology, then deliver upload-ready files.

Inspect the full assessment

Your next market starts with the lesson you already made.

Creators can buy cheap dubbing software. Some will pay more to receive a finished lesson with native-language review and consistent terminology. Sell a bounded audience experiment before promising a full multilingual course.

Intended buyer

A paid-course creator receiving Spanish-language requests before an upcoming promotion.

The offer

Three clips, 10 source minutes total → one Spanish version, captions, glossary and one correction round.

First version

English→Spanish, one voice, original visuals. No lip-sync, slide rebuilding, voice cloning or regulated subjects.

Main risk

Cheap DIY substitutes and labor can erase the margin. Text-heavy slides, jargon and tight synchronization expand scope quickly.

When to stop or rethink

Fewer than 2 paid pilots from 20 qualified creators, more than 75 combined review/production minutes per batch, or no repeat batches among the first five clients.
