T2 Field-leadingMilestone (age 21)
Co-founded DoorDash in 2013 at age ~21 while a Stanford computer-science student and served as founding CTO (2013–2019), building the core logistics platform that later IPO'd and made him a billionaire.
Born 1992 in San Jose to Taiwanese immigrant parents; one of four children. Graduated The Harker School (2010), then Stanford BS computer science. Roomed with Stanley Tang as a freshman; met Tony Xu in a joint engineering-business course; founded DoorDash as a class project (initially PaloAltoDelivery.com).

Question four · where did the leverage come from?
Andy Fang'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 Andy Fang'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, Andy Fang's starting-advantage total is at the 72th percentile. Separately, their built or converted leverage total is at the 82th 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.

Evidence summary
Andy Fang co-founded DoorDash at ~21 as Stanford CS student and founding CTO, shipping the technical core while the founders personally made deliveries. Elite prep (Harker) and Stanford plus Bay Area geography and a tight cofounder team (Tang, Xu) compounded on the on-demand logistics wave. Family background is Taiwanese immigrant San Jose; no strong documented parental tech apprenticeship, so peer team and institutional pipeline dominate.
