I have one of those awful people as a client right now. We spent hours with a truly fantastic marketer (and I don't throw that kind of praise around lightly, especially in marketing), who not only helped us identify great copy, but also helped us identify some broader values to give the company character. I sat in that meeting with the 2 founders. We took notes, raved about the meeting, had a bunch of great concrete stuff to move forward with.

A week later the CEO designed the startup's landing page. None of the good stuff from the meeting was there, just a generic uninformative slogan and a generic long parallax marketing page that doesn't tell anyone what the product does. Sigh.
