Just jotting down some ideas here:
Sub reddits – www.reddit.com http://www.reddit.com/reddits/ – get a few friends to rank your item and you could be on the first page of sub reddits (don’t worry about being on front page)
Buzzsumo – who is getting their content shared – these people listing their stuff are good to work with in JV’s
Check out the people promoting equivalent products e.g. financial products, find the affiliates = clickbank, clicksure, cpaoffers etc. Get them to list your own link ASWELL as (don’t ask them to remove old link)
Look for YouTube marketers
Look for bloggers i.e. do a search for subject +”blog”
