At HumanLayer, we’re on a mission to transform how teams build software with AI. If we had a motto it would be “No vibes allowed” – we believe AI agent-enabled coding is a deep technical engineering craftAnd we’re building CodeLayer to unlock this at scale. A June 2025 Stanford study said AI can’t solve hard problems or work well in complex or legacy codebases, and we’re proving them wrong with advanced techniques inspired by Context Engineering (a term originally coined by our CEO Dex in April 2025).
