I think this is likely just some angel investor's portfolio, with some other companies sprinkled in. A few alarm bells are going off:

* Explicitly filters for people who do not want a work life balance. If a job applicant says they found your company via this list, you don't have to ask, "Will you regularly work more than 40 hours a week for free?" They just told you.

* No information on why these companies in particular are special (everyone has a strong market/team/growth)

* No disclaimers regarding conflicts of interest

* Trying to establish a brand for some reason

* Published anonymously

Hopefully I'm not being too cynical. Just seems very financially motivated.
