New app to get notified when YouTubers talk about topics you care about. Who's interested in this?

Hey Indie Hackers! 👋

I would love your feedback on who you else think would be interested in the product I'm building to "scratch my own itch". Thanks in advance for any guidance you can offer! 🙌

Here are the details –

I want to know when YouTubers talk about certain topics I care about, without having to listen to every second of every video they publish (maybe you do, too!).

That's why I'm building VideoMentions.com. Our slogan is:
"Get notified when YouTubers talk about you, your company, or the things you care about."

It works like this:

1. You tell VideoMentions what words to listen for, and which YouTube channels to monitor.
2. The app sends you an email whenever a video is published with those words in its title, description, or the YouTuber's spoken words. ✨

I'm personally excited about using the service, but I'm not sure who else would be. It seems like a general-purpose tool that could benefit folks across a number of different industries, so I'm not sure how to niche down.

I'm thinking about targeting people in Marketing and in the Startup/Entrepreneurship world, since presumably those folks would want to know when their product or service is being discussed on YouTube. Any other niches you think I should explore?

Thanks!
