Severin Hacker'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 Severin Hacker'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, Severin Hacker's starting-advantage total is at the 84th 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
Hacker paired elite European CS training with a high-trust advisor relationship that became a cofounder partnership. Duolingo’s origin during his PhD (2009-2011) at ages ~24-26 is the <=26 milestone; public launch and scale came later. Institutional pipelines and mentorship dominate over family-domain inheritance.
