You have secured job offers as chief operating officer (COO) at two companies, both of which are in the advanced materials industry. Each of these companies launched three to four years ago and is experiencing a rapid growth phase.

The CEO of Company A is a materials science engineer who has also completed an executive MBA program, and her three patented inventions are the basis of the company's product line. This is the first company that she has led. Company A is backed by venture dollars.

Company B also has a robust patent portfolio, with the inventor/co-founder serving as the company's chief technology officer. The CEO of Company B was recommended by the venture capital firm that funded the latest growth stage. The CEO has a limited technical background but has led two companies to a successful exit (following two failures in his early career).

Based on the leadership profiles of the CEOs, and assuming all other things are equal, for which company and CEO would you prefer to work and why?
