This is the life of an entrepreneur. When I started all of my companies, I did not know what it meant to manage a team, venture, finances, hiring, firing, and everything under the roof.

All it takes is to start. Try looking at some of the best CIO's or CTO's in your industry or other industries and try to understand what makes them successful. One of my favorites is Dharmesh Shah from HubSpot. There are millions of talks by him and other top CIO's.

You can always join a small startup and because of your background in IT, you may get to work with a CTO. Be sure that the team is passionate and the CTO is someone you resonate with.

Bottom line - realize that it is okay to not know what you are doing. Let me know if I can help in any other way via call.
