Stack Overflow operates a dual-revenue model: a public Q&A platform with 83M+ questions, and Stack Internal, an enterprise knowledge system adopted by 20,000 organizations. The tech stack is heavily weighted toward infrastructure and security tooling (Terraform, CloudFormation, Docker, Okta, ServiceNow, AWS WAF, SASE, Fortinet), with active projects around SOC2/ISO 27001 compliance and SecOps maturity—indicating a push to strengthen enterprise security posture as the core competitive moat for Stack Internal.
