How do founders kill their companies? Most often by not understanding the basics of marketing strategy. I spent a pleasent hour at Draper University speaking to students about the top three ways Silicon Valley startup founders crash their own companies. Draper kindly provided video from the event, and you can watch the whole presentation.   For a full course on the basics of marketing strategy, get a copy of our book The Start-up CEO’s Marketing Manual at Amazon.com. (if you have technical difficulties watching the embeded video above, it is available at YouTube at https://youtu.be/Fly_JceiuWY).
