About Outbound

GPAgent's own fund-neutral profile, written from public information. Updated Oct 4, 2026.

Summary

Outbound builds a multi-channel messaging automation platform for mobile and web products. It lets non-technical marketers and product managers trigger emails, push notifications, SMS, and voice messages based on what users do inside an app, replacing hand-coded notification logic and one-size-fits-all broadcast campaigns. Built-in testing tools let teams measure which messages drive the actions they want.

Business model

Not specified in available sources.

Go-to-market

The platform targets non-technical roles, marketers and product managers, at companies with mobile or web apps, offering self-serve setup without engineering support.

Outbound organizes the messages you send around the actions your customers take. We allow non-technical marketers and product people to set up automated email, push notification, SMS or voice messages when you need your users to take an action, then test how well each message works.
