T2 Field-leadingMilestone (age 26)
In 2009 at about age 26 he co-founded the vertical real-estate search portal Jiujiufang (99fang) with college roommate Zhang Yiming—a material startup founding before ByteDance.
Born 1983 in Jiangxi Yichun; met Zhang Yiming at Nankai University (microelectronics, graduated 2005). After early jobs the pair cofounded Jiujiufang in 2009; in 2012 they cofounded ByteDance, where Liang led product R&D on Toutiao and later Douyin/Lark before becoming CEO in 2021.

Question four · where did the leverage come from?
Liang Rubo'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 Liang Rubo'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, Liang Rubo's starting-advantage total is at the 23th percentile. Separately, their built or converted leverage total is at the 45th 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
Caixin and Baidu Baike both place birth in 1983, Nankai graduation 2005, and cofounding of Jiujiufang with Zhang in 2009 (~age 25–26). ByteDance cofounding in 2012 is post-26 (~29). Long-running Zhang partnership is the dominant documented advantage; family wealth/domain not documented.
