As someone who has hired developers in the past. This "12 hours CTO" missed a good opportunity. It's much better to work 7/8 than 12. As frequently, developers when they get home. The itch will get too much and then start tinkering and learning new things in their personal time.

Being visible at a keyboard for 12 hours is not.
