Founders want to see what you're doing at all times, they know that you have to out in remote double time to actual get anything done. I can't solve incredible engineering problems with 5 people talking at the same time for 6 hours, I wind up having to work 18 hour days with 8 hours of face time sitting and chatting to make the crew of kids happy. As a senior dev my workload is triple the juniors so it's not unusual for me to have to do 80-120 hours a week for 40 hours pay to not lose my gig.
