Be as open as possible. The places I've worked that were basically "open books" and super transparent tended to be more successful than the more opaque places.

Be as open as possible. The places I've worked that were basically "open books" and super transparent tended to be more successful than the more opaque places. Largely because people felt they had more of a stake in it, felt more involved and engaged, and would bring more ideas/contacts/knowledge to the table, etc. The more opaque places that practiced unnecessary levels of "need to know" tended to not work as well, as the company couldn't leverage its peoples experience, networks, etc as efficiently, and people generally work less well if they are kept in the dark. Being open tends to create opportunities, and your employees can warn you about risks you might be missing. Being closed? You lose that advantage. A decent NDA and properly written contract will cover you if someone leaves.
