Per my comment, "...she apparently decided to change ("re-frame") her vision so that she could appease investors who were telling her the opportunity wasn't big enough to justify an investment."
The CEO of a company is ultimately responsible for setting the company's vision. Period. If the OP changed her vision to win over investors, she doesn't own that new vision any less. She had the ability to pursue the original vision.
There are lots of startups in Silicon Valley that have the potential to be profitable small and medium-sized businesses. They'll never get there because they are run by founders who are drinking the kool-aid and trying to turn their companies into businesses they will never realistically become. But this isn't the fault of the investors. It's the fault of the founders who lack the ability to recognize that the VC path isn't a fit for the type of company they're building.
I think it is really hard to resist the "dark side" that investors want CEOs to follow. You also have consider what happens to the company if the investors force a buyback on the founders if the company is not meeting their growth targets. Once you sup with the devil and accept outside money you really have no choice about the path you are on.
Are we sure this is her vision or that of her investors? The need for VC to generate "outliers" is wrecking a lot of really good businesses.
