Finding success in your first 100 days as the new CFO

So I guess maybe let's switch gears a little bit and dive into the specifics of the secrets of Rockstar CFO book that you wrote. I think as part of that you interviewed a number of Valley, startup CFOs, as well as fortune 50 CFOs as well. Can you maybe provide a bit more context in terms of, you know, the types of businesses they were involved in?
