I have personally started my own online health company. The biggest thing I have found after starting my venture, is a. know your niche, b. have an amazing product/service, c. know your audience. Start with that then you can build from there into creating a mission statement, writing a business plan, and starting the investment process. Know that it takes both time and money but with a plan, and patients you can make it happen. Feel free to reach out anytime.
