Kim Scott
Author of Radical Candor (over 1 million copies sold, translated into 23 languages) — the most-cited book on Lenny’s Podcast. Former Google executive who led AdSense, YouTube, and DoubleClick teams. Faculty at Apple University. CEO coach at Dropbox, Qualtrics, and Twitter. Earlier in her career: managed a paediatric clinic in Kosovo, started a diamond-cutting factory in Moscow. Working on a follow-up book, Radical Respect, which extends the Radical Candor framework into broader questions of organisational culture and identity.
Known for the Radical Candor two-axis framework — care personally × challenge directly — and for identifying ruinous empathy (caring without challenging) as the dominant failure mode in management feedback, responsible for roughly 90% of mistakes.
