Anyone interested in a Cross Promotion Marketplace?

I've been excited by the growth in newsletters and have been speaking with a lot of creators the past couple months. A lot of people have tried or currently do cross promotion to grow but say it's hard to find similar newsletters with similar audience sizes.

So, I'm thinking of creating a marketplace where newsletter creators can find and connect with other creators with similar audience size and overlapping subject matter.

I made a small landing page just to gauge interest. If you're interested, feel free to sign up: https://www.getcrowdmagnet.com

Would love any feedback on this and if you do signup for the list, I'll probably reach out to schedule a call so I can learn more about your newsletter and how you're looking to grow.
