All founders, mentors, and local leaders attending sessions of the Founder Institute have to sign NDAs before participating in the program. Your IP is safe. We also tell all of our Founders that in many cases, Founders change their ideas in the program and realize that for example there is no market for the idea to scale or that there are holes in the idea that cannot be filled and therefore should be dropped.
Additionally, your idea will never be able to be replicated the same exact way that you visualize it. Ideas are worthless, execution is everything. If you actually have a good idea, then there is a big chance that someone else out there is already working on it.
By restricting yourself to talk openly about your ideas, you forgo valuable opportunities to get feedback on your startup.
