Scored Meeting with Chief Product Officer, How to Handle?

I have caught the attention of a Chief Product Officer that operates in the same industry as my product. (Financial) Only difference is my product serves consumers, his products serve banks and lenders. I am very excited to meet with him but I have my reservations. I love sharing my idea and vision for my product with friends, family, and colleagues but am hesitant to share detailed plans for execution with someone who could build it faster than I possibly can. I still have a day job.

Or perhaps he could help me? I don't want to be close minded, but I don't want to put myself in a position where I see my product become one of theirs with a different name slapped on it. What is to stop them from moving into that consumer space?

Sincerely,

Paranoid Paul
