I've built Ship 30 for 30 - a cohort-based writing course - from idea to over 1,400 students in six months. I've learned a ton along the way about marketing, scaling, building community, iterating and improving a course, and made just about every mistake there is to make. I did all this while having a full-time job! I'd love to answer any questions you have on bootstrapping demand for your course, marketing, building, scaling, and everything in-between as well as how to manage side projects. AMA
