About Mantle
Summary
Mantle builds internal AI agents that automate back-office work for B2B companies. Founders and operators describe a task in a single prompt, and Mantle connects to tools like CRM, email, calendar, payments, and product analytics to run that work automatically. It replaces manual reporting, pre-meeting research, and routine email drafting that employees otherwise handle themselves.
Business model
Pricing is not public.
Go-to-market
Mantle targets small B2B teams that want to eliminate administrative overhead without engineering work. The prompt-based setup is self-serve, requiring no code to deploy agents.

Build internal agents to automate back office work with one prompt
Mantle connects to all your tools: your CRM, Mail, Calendar, Payments, Product Analytics, and more. With just one prompt, you can create agents that handle back office work for you. These agents can automate reports and email them to you, drafts emails right in your email client, generates pre-meeting research directly in your calendar event, and much more. They run quietly in the background, react to changes in real time, follow a schedule or work when you chat with them. You didn’t start up to stay stuck in admin. Turn your company AI-native with Mantle.
