Do I need a specific idea already to join the Entrepreneurship Program?

Absolutely not. Some of the people attending the program have multiple ideas they are considering, but don't know which to pick. Some have no particular idea, but are passionate about something in their lives, and want to create a business around that passion. And, some just want to start a business and don't know where to begin.

So this is definitely not a requirement. In fact, it may be best to join with an open mind and see where it takes you.
