I had an initial conversation with a Mr. Nick Adlinger about a beverage idea I had. I signed their NDA and sent them mine. Mr. Adlinger never signed my NDA. In addition, he told me his company would get back to me in a about week once they discussed my idea with their marketing people. I NEVER heard back from him. Is this how this company conducts business? I sent him an email and crickets....clearly, I will never use this company.
