JAMS is an automation orchestration and job scheduling solution that runs, monitors, and manages critical IT processes from a single console. JAMS automates jobs across Windows, Linux, UNIX, IBM i, z/OS, and OpenVMS, with native integrations for the databases, BI tools, and ERP systems already running your business. Jobs run on any schedule or trigger off other events, with dependency management keeping workflows in order and an audit trail logging every execution. JAMS includes two AI capabilities at no additional cost. JAX is an AI agent built into the JAMS Web Client: ask it a question in plain language, and it finds a job, troubleshoots a failure, or looks up how to do something, grounded in JAMS documentation. It acts only when asked, and every change waits for your approval. JAMS MCP brings JAMS into the AI coding tools teams already use, including Cursor, Claude Code, GitHub Copilot, and Claude Desktop. For teams managing thousands of jobs across SQL Server, ADF, Airflow, SAP, JDE, and Banner, this cuts tribal knowledge and middle-of-the-night troubleshooting. Knowledge that once lived in one person's head becomes something any team member can ask about directly. The AI lives in the product, not in the support queue. Support is staffed by humans JAMS will never outsource, based in the United States, the United Kingdom, and Australia. New tickets go to long-tenured engineers, and every JAMS customer has the CEO's cell phone number. JAMS' mission is to reduce the operational burden of critical automation, so teams spend more time on the work automation was meant to free them for.
