It sounds like you're a talented engineer who's comfortable working on the technical side of the house. If that's true, the biggest challenge you're likely to face is managerial. Being CTO in an agile environment is about managing the technology roadmap and making sure the technical team is shipping code as efficiently as possible. Your first goal should be fostering the creation of lightweight engineering processes that allow your team to operate without procedural roadblocks. Resist the temptation to "superman" your way through technical problems that could be delegated to slower team members. The CTO needs to remain focused on the big picture. I'd recommend 2 books: The E-Myth - which talks about how most small business (especially true of software companies) are started by "technicians" who must balance that trait with being an entrepreneur and a manager. I found it helpful for my transition. Now, Discovery Your Strengths - discusses how important it is to identify and play to the strengths in your employees and co-workers -- rather than trying to fix their weaknesses, which is a losing battle. Best of luck. With the open and humble attitude you're displaying, I'm sure you'll do great!
