Protect ideas/intellectual properties:[3] If the startup is working on a revolutionary product that would be easy to replicate - especially software ideas or relatively cheap new technology - 'going stealth' will avoid any details about the idea being brought in public and it being copied by another company. Usually employees will have to sign an NDA with the company. Applying for a patent is also a lengthy and expensive process, which is therefore often not a viable option for a recently founded company.
