In a 2015 Venturebeat post, Gregory Ferenstein writes that WordPress co-founder Matt Mullenweg used to sleep 6-times day while creating and writing WordPress codes. Before he founded Automattic Co., he was “simply an eager coder with a healthy attitude for self-experimentation”.

“Instead of just two cycles, Mullenweg did 6 sleeping periods a day (of about 40 minutes each), with about 2.5 hours in between each nap. He abandoned his extreme sleep schedule after getting a girlfriend” writes Ferenstein.

This was probably one of the most productive periods of my life. I wrote WordPress in that time.

According to the post, Mullenweg’s New Year resolution (that year) is to meditate 5 minutes a day, putting him among many successful tech founders who are also meditators.

Sleep Foundation states that ‘A Good Night’s Sleep Helps With Job Performance’.
