Leah Culver
Milestone (age 24)
In June 2007, co-founded microblogging/social network Pownce with Digg cofounder Kevin Rose and Daniel Burka, serving as cofounder and lead developer; the product became a high-profile Web 2.0 peer of Twitter and was acquired by Six Apart in late 2008.
From Minnesota; switched from art to computer science at the University of Minnesota (B.S. 2006). After early roles at iLoop Mobile and Instructables, she programmed Pownce largely herself and launched it with Rose and Burka in 2007 at about age 24, earning Fast Company/MIT Technology Review recognition while still under 26.

Leah Culver'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 Leah Culver'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, Leah Culver's starting-advantage total is at the 40th percentile. Separately, their built or converted leverage total is at the 57th 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
Culver's ≤26 milestone is cofounding and building Pownce (2007) as lead engineer with Digg's Kevin Rose and Daniel Burka—material, dated, and multi-sourced. She had just finished a CS degree (2006) and early SF startup jobs. Fast Company (Nov 2008) identified her as a 25-year-old founder/lead developer, and MIT Technology Review featured Pownce among startups to watch with her on the cover path. Advantage stack centers on complementary high-status cofounders and scarce full-stack product engineering rather than family capital.
