> the new guy sucks. Just gets everything done slower
You made 2 mistakes here.
1. The first employees were not excited, they were all on paid trial periods and have no equity.
2. The other developer who quit and myself by far did all the work. Staying all night does not mean you get the most work done. Actually, the founders played basketball most of the time and got no work done. Over the years I've learned to become increasingly productive during the day (with the help of coffee, eating right/being active) and I effectively built most of their product even though I would "sneak out" at 7 at times. Staying late at night or going in on weekends never advanced the product. Most nights would end in the VP Eng. and founders drinking wine and whiskey (this is a YC startup mind you). They didn't do anything despite being there all the time.
