All of F26About horizontal.
Every factory will be run by AI agents. Horizontal is building them. Today, the work that keeps production moving is scattered across people, teams, and disconnected software. When plans change, materials run short, or quality issues appear, factory teams piece together the context and coordinate the response by hand. Horizontal's AI agents take on that operational work inside the systems factories already use. They replan production around a disruption, investigate quality issues and coordinate order releases across teams and tools. Manufacturers start with one process and add agents over time, building toward a system that coordinates the factory end to end. Factories are demanding environments for AI: every plant has its own systems and procedures, and every action must work in the context of real production. Our team combines mechanical engineering and shop-floor experience with a track record of building and deploying agentic AI in global industrial companies. Horizontal connects the people, software and machines that run production.
