From a May posting to a classifieds website for Stanford University students. The post sought roommates for Startup Castle, a 17,000-square-foot Tudor mansion in Woodside, California.

Welcome, friends!

We’re building a community of excellence in one of the most impressive estates in Silicon Valley. We believe that the right people in a place like this can make for a great environment and geometric scaling of success for everybody.

You must:

 — have a top-class degree or job with a strong math/science requirement

 — exercise at least fifteen hours in a normal week

 — commute by car less than 20 percent of the time

 — prefer organized systems and common rules

This may not be the right place if you:

 — watch more than four hours of TV/movie/game entertainment per week

 — have more than one tattoo

 — have attended more than one protest

 — make more than three posts a week to social media

 — wear makeup more than twice a week

 — own any clothing, shoes, watches, or handbags costing over $500

 — have more than one Internet-app date per week

 — have a complex diet that requires lots of refrigerator space

 — drink alcohol more than three drinks per week

 — use marijuana more than twice a year

 — have been prescribed anything by a psychiatrist more than once

 — have used any other drug more than twice in your entire life

About the place: It’s furnished, and we stock the “generosity kitchen” with basic foods. As we get the permanent group settled, we’re hoping to do things as a group like fitness challenges, group dinners, bike rides, challenge outings, and working on building things together. Private rooms start at $1,750, shared dormitory for $1,000. More for private bathrooms, car parking, and extra people. Aside from being a cool place with great people, I really think this is the best deal in Silicon Valley, but let me know if you think I’m wrong.
