Using founders of $1B+ companies is absolutely using outliers and is evaluating survivorship bias.

As it relates to this article, a $1B+ company generally has product market fit and the founder has taken $10M+ off the table, which is more than they would have made in a regular job over a ~10 year period. The authors concerns don't apply in that situation.

I'm not using "founders of $1B+ companies" as my set. I'm using "founders who are my friends" as the set and it happens to include a couple of $1b+ companies but the majority are not (yet!).
