The enterprise software landscape is currently facing its most significant structural transformation since the move to the cloud.

This shift is driven by the emergence of “Vibe-Coding”—the concept that rapidly improving AI models can replace traditional software development—and the transition to “Agentic-First” autonomous systems.

This briefing outlines the threats to incumbent software providers, the pitfalls of this new paradigm, and the economic shifts defining the era of autonomous software.

The Core Disruption: “Vibe-Coding” and Agentic AI

Market sentiment in 2026 suggests a “Software is Dead” narrative, driven by the belief that traditional Software-as-a-Service (SaaS) is being disrupted by AI-native tools.

Threats to Incumbent Software Providers

Established software companies face “front door risk,” where their products are reduced to middleware. In this scenario, AI agents capture the majority of the value and expansion revenue, while legacy systems sit at the bottom of the technical stack as mere repositories.

The Erosion of the Per-Seat Model

The traditional SaaS model of charging per “user login” is becoming unsustainable. As AI agents replace human labor, the value of a “seat” diminishes.

• Outcome-Based Pricing: Providers are shifting toward charging for results (e.g., “pay per ticket resolved”) rather than access.

• Revenue Impact: High-performing AI agents can do the work of hundreds of human employees; if a vendor cannot charge for those human seats, they face a “Value Crisis.”

Conclusion: The Path Forward

The market is currently pricing software with a “shoot now, ask questions later” mentality, resulting in the lowest revenue multiples in over a decade (median 3.6x). Analysts suggest that only a small percentage—perhaps 10%—of legacy SaaS companies will successfully transition to becoming “AI winners.”

To avoid obsolescence, incumbents must:

1. Own the Data Moat: Turn proprietary transaction history and domain-specific data into a defensive advantage.

2. Transition to Outcome Pricing: Align their revenue with the productivity gains provided by AI.

3. Adopt Open Standards: Utilize protocols like the Model Context Protocol (MCP) to allow agents to connect across different platforms seamlessly.

While “vibe-coding” poses a legitimate threat to simple workflow tools, the robust moats of complex enterprise systems of record may provide them more resilience than the current market volatility suggests. However, the window for these incumbents to re-architect for an agentic, autonomous future is closing rapidly.
