The CEO is the business guy. As a CEO, you don't get to code. Instead, you'll get to do the paperwork, answering phones, making cold calls, a lot of meetings, and a lot of traveling. It's fun at first, but gets boring quickly for technical people. You have to be comfortable with that role and must be a good communicator and marketer. <p>It's a fancy title, but don't let that tempt you against your good judgement. The founders of a lot of technology startups go out and hire an outsider to be the CEO. Google is a good example. Even Steve Jobs hired a CEO in the early days of Apple. <p>If you're in the very early days, then just put Founder as a title for all founders. You don't need to get into conflicts too early.
