That is exactly the reason I am building https://presscatalog.com , I think solo founders can benefit by pitching to journalists directly. I would really really love if you can give me some feedback.
The first thing I noticed is that the pricing is monthly (and not trivial, at $90/mo to start). Do you expect folks to use the product for a short time when they're focused on PR, or would this be an ongoing thing? I can imagine that there would be periods where startups wouldn't want to be spending that much when they're focused on other things (product, fundraising).
