Disrupted

After twenty-five years as a magazine journalist, Dan Lyons loses his job at Newsweek at 51 and takes a marketing job at HubSpot, a Boston software startup steeped in relentlessly upbeat, youth-obsessed corporate culture. Disrupted is his account of the culture clash that follows — equal parts memoir of professional reinvention at midlife and a sharp, funny indictment of Silicon Valley's disposable attitude toward anyone over 40.
