Milestone (age 23)

Joined Facebook in 2005 at age 22–23 as one of the company's first ~15 software engineers after dropping out of a Stanford Symbolic Systems graduate program; helped build News Feed, a defining product surface.

Born 2 September 1982 in Atlanta and raised in affluent Winnetka, Illinois; attended New Trier High School. Earned a Stanford bachelor's in Symbolic Systems (AI concentration) and began a Symbolic Systems graduate program before leaving to join early Facebook in 2005.

Question four · where did the leverage come from?

Chris Cox's leverage provenance

Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Chris Cox's outcome attributable to any origin.

Luck is not a leftover score.

Structural luck, Encounter luck, Event luck, Outcome variance can change every arrow in the path. This successful-only dataset cannot observe the near-identical paths that did not break through, so luck stays visible and unscored.

Within Founders / operators, Chris Cox's starting-advantage total is at the 59th percentile. Separately, their built or converted leverage total is at the 20th percentile. Other T2 profiles average 7.9 / 24 starting advantage and 12.3 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.
