Empowering the world to develop technology through collective knowledge
Stack Overflow is the world's largest online community for developers, founded in 2008 by Joel Spolsky and Jeff Atwood in New York City. Its public platform hosts over 83 million questions and answers covering programming and software engineering, serving nearly every developer who codes. On the enterprise side, Stack Overflow offers Stack Internal, a knowledge management platform that brings human-verified knowledge and AI together to help engineering and technical teams collaborate, onboard faster, and solve problems without creating duplicative Slack or email threads. It also provides Stack Data Licensing — licensing decades of verified technical Q&A to power AI model training — and Stack Ads, which reaches developers directly in their workflow. Stack Overflow's knowledge base has been reused over 113 billion times.
