In short, because you can be sure that 13 MBAs will be a high-trust, high-quality community - also in 20 years.

There are lots of so-called exclusive networks out there, working on a ‘by invitation only’ basis. But what ‘by invitation only’ really means is that everybody can join, independent of qualifications, as long as they just know somebody who is a member. These networks are not really exclusive, nor will they remain trustworthy in the long run.

In comparison, every single person you will meet in the 13 MBAs community has been thoroughly vetted by the Admissions Officers at the world’s best business schools. Think of it as an extension of your own school’s alumni network – equally trustworthy, only 13 times bigger.
