Having worked in academic research and co-founded a startup I would admit that the working hours weren't that different. However, in a startup you have a much wider set of pressures - making payroll at the end of the month, keeping customers happy, investing your own money to keep the business going, hiring/firing/managing people etc. (it's a very long list).

Having had my own co-founded company gone bankrupt, I have to agree with you.
