Emmett Shear'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 Emmett Shear'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, Emmett Shear's starting-advantage total is at the 72th percentile. Separately, their built or converted leverage total is at the 31th 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
Shear's trajectory was shaped by an elite educational pipeline (Evergreen School for Gifted Children, Transition School at UW, Yale) and a remarkably early and durable peer partnership with Justin Kan, beginning at age 8. They were part of Y Combinator's inaugural class in 2005, giving them access to Paul Graham's mentorship and the nascent startup ecosystem. The launch of Justin.tv in 2007 rode the wave of broadband-enabled live video streaming. No specific family financial or domain advantages are documented, but the gifted school pipeline and early peer bond were clearly catalytic.
