📊 Financial & Retainer Economics

🎯 Market Opportunity & Why Clients Pay For This

Over 70% of YouTube views come from outside the creator's native language country. Top creators like MrBeast scaled to billions of views by dubbing their content into Spanish, Portuguese, French, and Japanese. Traditional dubbing studios charge $100+ per minute of audio. By assembling a modern pipeline using Qwen3-ASR for transcription, DeepSeek-V4.1 for translation, and voice cloning models, you offer creator dubbing at $15/minute with 80%+ profit margins.

  • Online course creators and coding bootcamps on Udemy/Teachable
  • YouTubers with 50k+ subscribers wanting to launch Spanish/Portuguese channels

Subject: Your video translated into Spanish in your own voice (Demo attached)

Hi [Creator Name],

Over 500 million people speak Spanish, but your channel is currently 100% English. That means you're leaving thousands in ad revenue and course sales on the table every month.

I took your top video on [Video Topic] and translated a 60-second clip into Spanish—cloning your actual voice so it sounds completely natural.

Watch the demo here: [Loom / Drive Link].

We run the entire localized channel for you: we translate, dub, lip-sync, and upload every new video you release for a flat $1,500/mo retainer. You literally don't have to lift a finger.

Would you be open to testing this with your next upload?

Best,
[Your Name]
