AI Market: a16z Backs Cognition's Agentic Coding Future
a16z founder Marc Andreessen published an opinion piece announcing continued investment in Cognition, the company behind the AI coding agent Devin. Three years after its founding, Devin now writes over 90% of Cognition's production code, up from 13% in the past year. The article highlights customer results such as Mercedes Benz completing a COBOL migration in 8 days versus eight months, Rivian achieving 10x test generation velocity, and Itau automatically remediating 70% of security vulnerabilities. Andreessen frames this as the next phase of 'software eating the world,' where software development accelerates at the speed of compute. This is an opinion/investment thesis piece, not a funding announcement, and reflects a16z's conviction in agentic coding as a transformative technology.
Highlights the growing role of AI coding agents in software development, which is a key infrastructure trend relevant to AdTech and MarTech, but lacks specific industry impact metrics.
