I'm a member of the product team at Treehouse, and was employee #3. We don't go around talking about the 4 day work week because it's something that we think is a great gimmick that we were fortunate enough to be able to pull off because we hit the VC lottery. It's something at the core of who we are as a company and something we've seen help us compete - not only in hiring but also in productivity. We see a huge benefit in rest, fresh thinking, and a healthy balance between our work and the rest of our lives. The 4 day work week builds that into who we are. It's not the only way to achieve those goals, but one of the primary ways we pull it off.

We've been working the 4-day work week far longer than we've had VC money. Our first investment came in the fall of 2011, long after we existed as a company, and we were profitable prior to raising VC.
