Agentic Era Restructures the Software Stack
The essay argues that the two‑decade software design model—centered on a fixed UX, narrow features, a thin data layer, and static API endpoints—is breaking because the consumer of software surfaces is no longer predictably human. By 2026, consumers may include humans, autonomous AI agents querying products via Model Context Protocol (MCP) servers, multi‑agent systems using Agent‑to‑Agent (A2A) protocols, or oversight layers (AG‑UI). These agentic consumers can query products unexpectedly, compose capabilities across systems, bypass GUIs, or call underlying services directly, undermining assumptions that enabled traditional SaaS design. The shift implies product teams must rethink interfaces, APIs, data and orchestration layers to serve machine consumers and new forms of integration.
Frames a broad, strategic industry shift from human-centered SaaS workflows to agentic AI stacks; implications affect enterprise software vendors, data infrastructure providers, payments, compliance and MarTech strategy.

AI Shifts SaaS Value to a New Context Layer
This essay argues that generative AI is reshaping the enterprise software stack by commoditizing code and many point SaaS applications while creating a new, high-value "context layer" that encodes institutional knowledge and directs AI agents. The author describes software splitting into three layers—systems of record (databases), point-solution applications (per-seat SaaS), and the emerging context layer (orchestration + institutional meaning)—and explains why growth, margins, and switching costs for many legacy SaaS firms are under pressure. Examples and competitive positions cited include OpenAI’s Frontier (described as an "intelligence layer"), Anthropic’s Cowork, ServiceNow’s collaborations with model vendors, and firms like Notion and Glean targeting institutional knowledge. The essay contends the context layer captures coordination overhead previously borne by payroll, compounds with agent usage, raises switching costs, and will be a strategic battleground for enterprise software value.
When Software Goes Headless: Defensibility Shifts
This a16z opinion essay examines how the rise of AI agents and headless product offerings (exposing APIs and data layers without human UIs) change what makes enterprise systems of record defensible. Using Salesforce’s recent announcement to open APIs and market a “headless” product as a prompt, the piece argues that agentic workflows weaken UI-driven stickiness and shift durable advantages downward into data models, permissions, workflow logic, compliance, proprietary data and network effects, and upward into real‑world execution. The article outlines three buyer paths (incumbent+agents, DIY, or AI‑native replacements), highlights factors that will matter for future defensibility (proprietary data, closed-loop action, network embedding, permissioning for agents), and identifies practical opportunities for builders in domains where software coordinates real-world operations.
Cloudflare Aims to Own the Agentic Web
The article argues the web is shifting from human-centric usage to an 'agentic web' dominated by AI agents. Simultaneously, software usage is moving from human-operated SaaS toward agent-operated services (coined 'AGaaS'). The author frames the combined shift of web and software primary users—from humans to AI agents—as a major structural change with wide implications for software, SaaS businesses, and web infrastructure.
