Build internal agents to automate back office work with one prompt

Mantle builds automated back-office agents that connect to a company’s tools, generates tailored agents from a single prompt, and runs them in the background to handle tasks like data retrieval, updates, and composing replies. The product aims at teams seeking to automate repetitive work and improve efficiency, using a context layer to guide agents across tools (CRM, emails, calendars, etc.).
