There are numerous ways to raise capital. It will depend on your goals and your resources. Most likely you will raise money from friends and family first and use your own money too of course. That's how we started our company that now has three brands. A crowd-funding campaign with a platform like Indiegogo.com is a great way to expand on that circle of friends and get them engaged in sharing.
Another way to get money is to pre-sell your products and use that money for production. You should be past the sampling stage and have your production lined up for that to work.
Please schedule a call so I can find out more about your circumstances and make more specific recommendations.
