Great project, I've been looking for something like this many times, looks like I'm your user :)

1. Try using your platform to fund your marketing yourself. Create a ticket “Help with money for marketing” and issue your HN post as a separate article on different social platforms for indexing by Google and provide a link on social networks to this ticket.

2. Contact VCs and write to investors. This is a direct path to marketing. Do not be afraid :)
