Also worked at Pivotal, and this is definitely true. The number of meetings is must lower than in other firms (in my experience), but meetings are still a part of life. Breakfast, though, is such an amazing operational hack that I'm surprised the article didn't go into more detail. Humans are very rhythmic creatures, and our circadian rhythms are moderated a number of environmental factors -- the big two being sunlight, and food. By having both breakfast and lunch happen at the same time each day, your body adjusts to getting at least two meals on a regular schedule, which helps with maintaining a constant energy level throughout the day. On top of that, it makes it physiologically more difficult to be late to work. Your body knows that a meal is coming up and you will tend to wake up on time. And while, yeah, you don't leave at 6:01, it's pretty rare to see people at the office after about 6:30. So, it's pretty easy to get to sleep at a consistent time as well. This is important enough that it's part of one of my conference talks: that a regular cadence throughout the day, including set meal times, is a great way to boost happiness, improve health, and more importantly, get more "quality hours" out of the day.
