Andrew McCollum'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.

No decisive linked signal
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Andrew McCollum'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, Andrew McCollum's starting-advantage total is at the 40th percentile. Separately, their built or converted leverage total is at the 45th percentile. Other T3 profiles average 7.0 / 24 starting advantage and 11.7 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.

Evidence summary
McCollum's path to co-founding Facebook was driven by being at Harvard at the right time and knowing Zuckerberg through CS classes. The elite Harvard environment concentrated opportunity and placed him among a peer group of future founders. The social media wave of 2004 was a massive structural tailwind. His complementary team with Zuckerberg, Moskovitz, and Hughes was exceptional. Family background is not documented, but the Harvard platform and peer network were the dominant advantages. By age 20, he had co-founded one of the most consequential companies in technology history.
