5. CEO talked about useless details

Incident: “One CEO spent 45 minutes on the first slide telling the story of how the company and founder team was formed, and how the idea was generated." says Don Rainey, of Grotech Ventures.

Reaction: “No deal’” said Don as an answer to the CEO’s useless blabber.

Lesson: Quite obviously, when pitching affront an investor, keep your mind away from all the use less and not-so-important stuffs and get directly to the point.

6. Bending around the NDA

Incident: “When the entrepreneur came in and pulled out an NDA to start the meeting. I explained to him why I wouldn’t sign it and he spent the next 10 minutes walking around the business idea without really telling me about it,” a VC reported to Business Insider.

Reaction: The investor pulled out of any further discussions and stopped the meeting immediately.

Lesson: Either let the VC know about all the business or production plans you have in mind or do not ever propose signing of an NDA if the VC is not ready.
