You wouldn't hire Elon Musk to turn anything into PayPal, as he wasn't a founder nor truly even an employee or executive of PayPal. Musk joined PayPal via merger with his fledgling X.com online bank. It was Confinity's PayPal product that continued from the merger, not Musk's X.com product. Musk was appointed CEO of the combined business, but contributed nothing of note to it. He was only there for a few months before the board ousted him from the company, while on vacation: his regular absence from the job was one of the reasons. The other was that his contribution to the engineering direction of the company amounted to "let's stop working on the business, and instead rewrite the platform on .NET to run on Windows servers", which the organization found so preposterous they circulated a petition to the board among the engineers to have Musk removed. The board did so.
