I recommend picking up this book and signing up for the course (Starts Feb 1st) (Free through NovoEd: https://novoed.com/scaling-up-yo...) The course and book is produced by the Stanford Graduate School of Business and hosted by Professor Huggy Rao and Professor Bob Sutton. From finding a hot cause to developing your team's core values, I think the framework they provide here is key to developing a successful startup. I had the pleasure of taking the course last year and getting highlighted in the top 8 group for the final project.
