Just read a great post by Jeff Bussgang (Flybridge general partner).  Full title is “Why Venture Capitalists Invest in Pigs, Not Chickens“.   The point about young companies with under 40 employees not needing a COO is pretty powerful.  CEO needs to be “all in” and all over the company.  Mark Suster just wrote about this exact topic as well; his post is titled “Why Your Startup Does Not Need a COO“.   There are obviously exceptions to everything.

Good reading.
