Documented path
Built the directory while at Stanford, at a moment when web navigation was unsolved and user demand was exploding.
Born in Taipei, Taiwan; father died when he was two; mother moved the family to San Jose, California in 1978 where she taught English to immigrants; knew only the word 'shoe' in English upon arrival.
Founding partner of AME Cloud Ventures; chair of the Stanford Board of Trustees; net worth estimated at ~$2.6 billion as of 2025.
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 Jerry Yang 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?
Graduated first in his high school class, student body president. Earned BS and MS in electrical engineering from Stanford in four years while working part-time. Above-average ability and drive, but not a prodigy.
Where it was dropped
0Neither way
What money, family standing, network, or permission was already in place before the work began?
Father died when he was two. Mother was an English professor who moved the family from Taiwan to San Jose when he was 10. Immigrant family with modest means — knew only the word 'shoe' in English upon arrival. No financial or domain advantage.
The shape of the track
+2Tailwind
What place, timing, institution, or peer group made the next step available?
Stanford provided the research environment and partnership with David Filo. Early web timing was perfect — built Yahoo directory when web navigation was unsolved. Stanford's EE department and Silicon Valley geography.
A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: High. 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
This records repeated behaviour or recovery described by sources; it is not a grit or merit score.
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, Capital safety, Domain proximity.
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.
Legendary or globally iconic career standing. The tier summarizes documented career recognition through the data cutoff—not Jerry Yang'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.
One or more documented starting advantages plausibly enabled this lever.
One or more documented starting advantages plausibly enabled this lever.
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.
No current annotation distinguishes self-built, enabled, or earned origins for this lever.
One or more documented starting advantages plausibly enabled this lever.
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Jerry Yang'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."
Immigrant family; no major financial advantage established.
No directly relevant parental domain advantage established.
Built the directory while at Stanford, at a moment when web navigation was unsolved and user demand was exploding. Family: Immigrant family; no major financial advantage established. Parents/family: No directly relevant parental domain advantage established.
