XMTP

SDK-based messaging platform for app developers

Overview

XMTP provides a platform for developers to integrate messaging capabilities into applications. Its core offerings include event-based notifications, one-to-many messaging, and one-to-one messaging through software development kits (SDKs) and development tools. Developers drop these features into their apps to keep users informed, foster conversations, and build communities. The product works by embedding XMTP’s SDKs into an app, enabling real-time messaging and notifications while prioritizing privacy and speed. XMTP positions itself against competitors by focusing on clear developer tooling, scalable messaging across chats and broadcasts, and a privacy-oriented, fast experience for users. Its goal is to help apps increase user engagement and community building by providing easy-to-integrate messaging features that can scale from startups to Fortune 500 customers, generating revenue through usage of its SDKs and services.
