Documented path
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).
Born 1992 in San Jose, California to Taiwanese immigrant parents; raised in the Bay Area and educated at The Harker School before Stanford.
DoorDash co-founder and head of consumer engineering; owns roughly 4% of the company; net worth on the order of $1–2B; married tennis player Carol Zhao (2024).
Where the conditions came from
Each is placed on a −1 to 3 scale from documented evidence, and the three are never added together. A combined total would rank Andy Fang against other people. Held apart, they explain why this path ran differently from another one—which is the only comparison this project supports.
The marble itself
+1Tailwind
What capability, drive, or early skill is documented in the person rather than their surroundings?
Harker School and Stanford CS graduate. Excelled academically but no evidence of prodigy-level ability or early exceptional output. Exposed to CS early via a summer class his mother enrolled him in.
Where it was dropped
+2Tailwind
What money, family standing, network, or permission was already in place before the work began?
Taiwanese immigrant parents in San Jose, one of four children. Harker School (elite private school in Silicon Valley) indicates significant family educational investment. Bay Area location with immigrant-family emphasis on education.
The shape of the track
+3Tailwind
What place, timing, institution, or peer group made the next step available?
Harker School (elite private), Stanford CS, Silicon Valley, and the DoorDash cofounder trio (Tang, Xu) formed as a class project. YC backing and the on-demand delivery wave. A once-in-a-generation peer environment at the right place and time.
A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: Medium. These are analyst readings of what the sources record, not measurements of merit, talent, or effort. The twenty-two scored dimensions remain available inside the deeper research detail.
What moved through the conditions
Silence in a biography is not evidence that perseverance was absent.
This is an unchosen opening or condition in the record, not an estimate of how much luck caused the outcome.
Strongest documented signals: Elite institution pipeline, Frontier geography, Exceptional peer / cofounder.
Describes the starting position, not what the person later made of it.
Strongest observed levers: Complementary team, Started serious reps before 20, Prior reps.
Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
The timeline below shows the sequence of work and transitions around the selected early milestone. It is evidence of a path, not proof that every step was necessary.
Dominant figure at the top of a field. The tier summarizes documented career recognition through the data cutoff—not Andy Fang's worth or future potential.
Question four · where did the leverage come from?
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.
One or more documented starting advantages plausibly enabled this lever.
One or more documented starting advantages plausibly enabled this lever.

A structural wave is external to the person, even when their position improved access to it.

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.
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.
Multiplying capacity documented later in the path. Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
Access or conditions documented near the beginning of the path. Zero means "no clear evidence in reviewed sources," not "advantage was absent."
Taiwanese American family in San Jose Bay Area; parents immigrated from Taiwan; one of four children.
Not documented as tech founders; immigrant professional/family context in Silicon Valley geography.
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.
