Part of a CFO's job is finding the cheapest capital source for the companies growth, sometimes that raising private equity and sometimes that is raising public equity (from IPOs). Also, being public is a resource drain on the organization. You have to comply with SEC guidelines, employees have to be watched for insider trading, all of your company financials and other details are now public for the world to see. Sometimes the burden doesn't make sense for a high growth company.
