After a couple of years catering for the growing company, one of Google's financial analysts told Ayers that the business was about to go big, and that he should get stock options before it went public. To invest in Google, Ayers borrowed $14,000, the equivalent of around $25,000 (£19k) in today's money, from his father, who warned him that if it was a scam, he would have to pay every dollar back.
When Ayers (pictured) left Google in 2006, his 700,000 shares were worth around $40 million, the equivalent of $62 million (£47m) in today's money. This allowed him to open his own restaurant and pay back his dad – and then some.
