About horizontal.
Summary
horizontal. builds AI agents that run manufacturing operations end-to-end, sitting on top of the ERP, MES, QMS, and CMMS systems factories already use. The agents handle the coordination work that today falls to factory teams: replanning production after a disruption, tracing quality deviations to their source, and releasing batches as soon as checks clear. Target customers are enterprise manufacturers in process, batch, and discrete industries in Europe and the US.
Business model
Demo-led sales; pricing not public.
Go-to-market
Enterprise manufacturers engage through a direct sales motion, starting with a single operational process and expanding agent coverage across the plant over time. Deployment runs on existing plant systems with no replacement of core infrastructure required.
From the Y Combinator listing
AI agents that run factory operations end-to-end.
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.
