  • StrongDM's AI team builds software without human-written or reviewed code, using AI agents.
  • The team follows principles like 'Code must not be written by humans' and 'Code must not be reviewed by humans'.
  • A key innovation is using scenario testing as holdout sets to validate software without human intervention.
  • StrongDM introduced the Digital Twin Universe (DTU), cloning third-party services like Okta and Slack for testing.
  • The DTU allows extensive testing without hitting rate limits or incurring high API costs.
  • Techniques like Gene Transfusion, Semports, and Pyramid Summaries enhance AI-driven development.
  • StrongDM released Attractor, a non-interactive coding agent, and cxdb, an AI Context Store.
  • The team demonstrated rapid progress, showcasing agentic workflows and DTU clones within months of formation.
  • This approach represents a shift from writing code to building systems that autonomously generate code.
