From Wild Web to Agentic Stacks: How AI Will Redefine Enterprise Software

The discussion around the perceived 'SaaSpocalypse' at Web Summit Vancouver was less about doom and more about a fundamental shift in user interaction. The central thesis, championed by industry veterans like David Shim (Read AI) and Avery Pennarun (Tailscale), is that Agentic AI is not replacing SaaS; it is fundamentally changing who the primary user of software is. This means the end-user persona is migrating from the human clicking buttons to an intelligent automated agent.

This shift implies a powerful consolidation effect, echoing the early days of the internet when thousands of niche websites eventually folded into dominant platforms. Instead of needing dozens of specialized tools—the 'hairball' of modern enterprise software—enterprises will increasingly adopt integrated stacks where lighter applications are absorbed or superseded by AI functions. The heavy lifting, the core system-of-record processes (like CRM or meeting management), will remain, but their interfaces and operational logic will become highly automated and autonomous.

David Shim’s observation regarding market valuation—that growth rate slowdown, rather than total collapse, is the current concern—provides a crucial commercial lens. The anxiety of investors focuses on perceived diminishing returns from software spend. However, the reality suggests that AI doesn't reduce spending; it changes how the money generates value. By having an autonomous agent act as the primary user, companies can connect disparate systems into complex computational workflows previously requiring manual human orchestration, creating a powerful new layer of enterprise utility.
