Back during the dotcom days, most employees, from secretaries to engineers, got extremely rich from options when the company IPOed. These days, in order to make a life-changing amount of money at a YC startup as an employee, the company needs to exit/IPO at over $5 billion in order to make about $1 million. I was at a YC company for 4.5 years as an early engineer, and I ended up with less than $100,000 from my options. I would have made 10x that had I taken a FAANG offer with considerably less work and risk.
