Congrats and thanks for sharing details about your business. I'm currently building a subscription based medical training video streaming site. May I also ask for details about the technical aspects? Do you use a media streaming service like Wistia? How do you protect your videos from unauthorized access? Do you serve different formats to different devices? Thanks in advance for answers.
