Question four · where did the leverage come from?
Stephen Cohen'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 Stephen Cohen'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, Stephen Cohen's starting-advantage total is at the 72th percentile. Separately, their built or converted leverage total is at the 72th 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
Cohen co-founded Palantir at 20 as a Stanford CS student after Clarium Capital exposure under Thiel and research with Andrew Ng. He built the early prototype and has remained president/board member through IPO and beyond. Advantages center on Stanford technical training, Thiel network, and complementary cofounders rather than documented family capital.
