Aaron Iba
Milestone (age 24)
Co-founded AppJet (YC, 2007) at age ~24; launched Etherpad (first widely noted web realtime collaborative editor, 2008–2009) and sold AppJet/Etherpad to Google in December 2009 at age 26.
Born June 18, 1983; grew up in Lexington, Massachusetts; MIT mathematics degree (2005). With David Greenspan won MIT Battlecode (2003); founded AppJet in YC, pivoted tools into Etherpad, then joined Google post-acquisition; later YC partner (2011–2013) and PayGarden founder.

Question four · where did the leverage come from?
Aaron Iba'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 Aaron Iba'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, Aaron Iba's starting-advantage total is at the 84th percentile. Separately, their built or converted leverage total is at the 86th 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
Iba’s path is classic elite-pipeline + technical depth: MIT, competition-winning partnership with Greenspan, YC-backed AppJet, and a category-defining collab product (Etherpad) acquired by Google by age 26. Family background is sparsely documented; institutional and peer advantages dominate the early stack.
