From a homemade media browser to Discourse, Sam Saffron has kept finding work hidden inside everyday annoyances. Now the co-founder and co-CEO is asking what AI saves us - and whose time it spends.
He helped programmers find answers, then gave online communities a place to talk. Now the co-founder of Stack Overflow and Discourse is putting family wealth behind a familiar idea: people deserve a chance to help themselves.
An imaginary leap day, a door that closes, a question with an answer. Joel Spolsky has spent his career noticing the small things that make software hard to live with - and building companies around them.

Before Airtable could make databases feel easy, someone had to make the difficult machinery hold. Emmett Nicholas took that job - and largely stayed out of its way.

Dave DeLong is a software craftsman with fifteen years of building iOS and macOS apps that ship on billions of devices - and, he likes to point out, some that run in outer space. A seven-year Apple veteran who worked on Siri, UIKit, Apple Maps, and Developer Evangelism, he led the WWDC app from 2013 to 2015 and helped ship the first releases of Swift, WatchKit, HomeKit, and HealthKit. He is among the top contributors of all time on Stack Overflow, a fixture of the Swift Evolution process, and the author of widely cited open-source libraries on calendrical math. He blogs at davedelong.com, speaks at conferences worldwide, and is currently building a stealth startup.
