Milestone (age 25)
Founded Retool in January 2017 at age 25, went through Y Combinator's Winter 2017 batch, raised $1.5 million, and grew Retool to $2M in ARR by August 2018 at age 26, later building it to a $3.2 billion valuation.
Born around 1992 in Palo Alto, California, Hsu grew up in Silicon Valley with parents who had immigrated from China for post-graduate studies. He graduated high school early, spent a gap year in China, and attended Oxford University to study philosophy and computer science. During his senior year at Oxford in 2015, he built a peer-to-peer payments startup called Cashew, which he brought to Y Combinator's Winter 2017 batch before pivoting to Retool, an internal tools platform for developers.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of David Hsu's outcome attributable to any origin.
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, David Hsu's starting-advantage total is at the 92th percentile. Separately, their built or converted leverage total is at the 11th 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
Growing up in Palo Alto with Chinese immigrant parents who came for post-graduate studies gave Hsu deep Silicon Valley immersion from childhood. His Oxford education in philosophy and computer science provided an elite academic foundation. The direct domain insight for Retool came from building internal tools for his own failed fintech startup Cashew, giving him lived experience of the problem. His parents provided material support by housing the startup team in their childhood home. The Hacker News launch in August 2018 drove immediate inbound growth, and Retool reached $2M in ARR before its public launch. YC and Sequoia backing provided elite ecosystem access.
