Thus far (Redoing my Kickstarter again), I've noticed that every time I start a kickstarter campaign, I'm bombarded with like emails and messages of "Promotion" and "Marketing" companies all willing to take my money claiming they will bring me users and help me to get more backers.
After trying out a few of these, I can 100% tell you that they are a waste of your money and will only be taking your money from you instead. A lot of them prey on new and innocent Kickstarter users who are just getting started.
I'd recommend asking around for reputable companies that can really help, thats just my own two cents on that for anyone else starting out
