There are a few key roles you need to fill in your startup.  What you call them is up to you.  Whether you fill them with fewer people is also.

•  You need the the person that is the face of the company and sells to the market, investors, partners, board members. (CEO)
• You need the person that gets things done.  (COO)
• You need the person looking for the next big thing (CTO)
• You need a rainmaker.  The one that finds customers and closes deals. (VP Biz Dev.)
• …and you need good advisors.

A lot of technology starts get heavy on one end.  Launching a company is not the time to develop new business skills.  Find the right people.
