About Stamp
Summary
Stamp builds an AI-powered email and calendar assistant for individual professionals. It drafts replies in the user's voice, prioritizes and categorizes incoming mail, tracks action items, and schedules calendar events, replacing the manual triage and composition work people do themselves today. The product learns each user's preferences through stored memories, contact history, and custom workflow rules.
Business model
A free entry point plus paid plans, as shown by the Pricing page on the site.
Go-to-market
Stamp targets individual professionals directly, with a self-serve model available via web and a mobile app, letting users sign up and connect their inbox without a sales process.

The AI Native Email Client
Stamp is the first AI Native inbox. It's more than an email client, though -- it's like your second brain. Stamp can respond to emails in your voice, organize your inbox to filter out the noise, keep track of action items, and automate essentially every task you're doing manually in your inbox today.
