Jeff Ralston

Jeff Ralston appears in Paul Graham on Y Combinator’s Growth, Myths, and the AI Era through Paul Graham’s account of the Y Combinator leadership transition after Sam Altman chose OpenAI. Graham says YC picked Jeff, already a YC partner, as successor; Jeff led for about three years before wanting to retire, after which Garry Tan became the fit Graham felt strongest about.

The page’s role is source-scoped: it marks Ralston as the bridge between the Sam Altman period and the Garry Tan period in this account of YC continuity.
