Trelium is an AI agent-building platform for teams automating repeatable business operations across the software they already use. Teams can describe workflows in plain English, inspect and edit the resulting steps, and use agents for tasks such as purchase-order entry, invoice matching, order updates, and customer replies. Agents connect through integrations or approved browser actions, with human approval steps, run logs, and retries available for oversight. Trelium also offers deployment in a customer-controlled data center or private cloud.
