I'm a software developer who developed a SAAS (software as a service) system for a startup company. I can't provide any additional details into the company since it's under an NDA but they shouldn't be super relevant to my question. I've been working for awhile for pennies on the dollar with the promise of that scaling as we earn more clients. Currently, we retain the rights to half of the product since we were willing to work for so cheap. It's coming time now where we relinquish our ownership of the product in exchange for a small amount of equity.
My question is, what can we do that would prevent the owner of the company from being able to create a new company and purchase their own company for $1 giving us practically nothing?
