At minimum, you have to provide a snapshot/example of what you're building.

I'm most intrigued by your comment pile digestor. I've often wanted something like that while cruising the Internet but I'm not sure how'd you monetize it. In the commercial world, software for analyzing customer-submitted questions and comments has been a valuable service for a long time, even before AI/ML engines came along. So, that's useful but it's a hard problem, very domain-specific.

Anyway, as others have said the main things you have to do to attract interest/business are: 1) Explain specifically what pain you are solving for what specific user/customer, 2) Offer specifics (examples, features) of how you solve that pain better than anyone else.

Who are your competitors? What makes you different?

Interactive is hard

1. People prefer reading and watching

2. Getting interactions to work well across platforms is going to have your agents endlessly spinning their wheels

Cold emails are not marketing, that is more often considered sales, or even more so spam. Waitlists are largely meaningless. Don't try to talk to investors until you have users using the platform

Your best strategy is to work on a problem you have in a domain you already deeply understand. If your picking be cause it looks like you can make money, you will fail.

Focus on problems, not solutions, which need to be flexible

Ship early, ship often. Waitlist is a sign of interest, use and the willing to pay you is success outcome criteria. Optimize for success, get and remain close to the user customers. Wishing you success.

You will learn the market by shipping and aggressively iterating on customer feedback.
