GoKawiilEssay argues SaaS companies are evolving into 'harnesses' around AI models
A tech essay describes a trajectory where software companies increasingly wrap their operations around large language models, moving from engineers pairing with coding agents to entire teams triggering and reviewing background agents, and eventually to agents proactively deciding work themselves. The author terms this evolving structure a 'harness' — the infrastructure, interfaces, and state built around a stateless model — and suggests most SaaS businesses are already on this path, whether they recognize it or not.
GoKawiil's interpretation of the reporting above, not reported fact.
The framing suggests that competitive advantage in software services could shift from proprietary code to how well a company designs the scaffolding, review processes, and orchestration around AI models. If this trajectory holds, it implies significant restructuring of engineering, product, and sales roles toward supervising and prompting automated systems rather than performing tasks directly. The essay's own author frames this as speculative but treats it as a near-inevitable industry direction.
- The essay defines a 'harness' broadly as all infrastructure, context, and state surrounding a stateless LLM.
- It outlines a multi-stage progression from human-run SaaS to agent-orchestrated companies.
- The author argues this shift could eventually mean agents, not humans, orchestrate core business operations.
