Many MLM companies recommend starting with a list of 100 people you know, called your warm market. Although it's not a bad place to start when looking for customers and business builders, the technique could also backfire and get to the point where you're annoying friends and family. You're better off spending your time finding people who are interested in what you've got rather than trying to convince your commuting buddy to sign up when he doesn't want to.
The main website a lot of people use when they are online is social media. These websites are where you can sit there and talk to anyone around the world that you know, and chances are that most people you know have an account on these kinds of things. You’ll want to make sure you do some looking into making a business account, because marketing through your personal profile may not do so well for you. Social media sites are free to use, but they also have ways you can pay for ads that go out to people.
