Microsoft × Publicis Partnership
Simultaneously with Agent 365 GA, Microsoft announced a strategic partnership with Publicis Group (world’s third-largest advertising and marketing group).
Gartner predicts: By end of 2026, 40% of enterprise applications will embed task-specific AI agents.
Landscape: Agents Consuming Apps
Old paradigm (2020-2025): Humans open apps → operate within apps → AI occasionally assists
New paradigm (2026-): Humans tell Agents goals → Agents choose tools → Agents execute and report
Apps are evolving from “human interfaces” to “Agent tools.”

Risk Warnings
- Agent permission boundaries: Improper permission configuration can lead to data leaks

- Employee resistance: Transition from “using tools” to “managing Agents” requires cultural change
- Vendor lock-in: Once deeply embedded, migrating to other platforms will be extremely difficult
