Perhaps instead of your ideas, it’s worth seeding your own personal make up with a firm statement of ethics??
Are you the kind of person who will hijack conversations to promote your product? Or do you have integrity?
Just purely out of concern for your business, do you have a cofounder who could handle marketing for you? If so, consider letting her have complete control over that function. It’s genuinely sad to see a founder squander goodwill on shitty marketing.
