Linq is a programmable messaging infrastructure platform that helps developers build applications and AI agents that communicate with users through native messaging channels. Its API provides access to iMessage and RCS functionality while also supporting SMS and voice for broader communication coverage. Developers can create experiences that include emoji reactions, voice notes, rich media, typing indicators, group chats, and other interactive messaging features. These capabilities make it possible to build conversational products that behave more like a direct contact in a user's inbox than a conventional application interface. Linq can be used for AI assistants, fitness coaching, restaurant reservations, market alerts, travel services, customer engagement, and other workflows where ongoing conversation is useful. The platform is designed to let teams integrate messaging into existing applications without having to build and maintain the underlying delivery infrastructure themselves. Documented APIs, developer tooling, sandbox access, and technical support help teams move from experimentation to production more quickly. Linq emphasizes scalable delivery with low-latency infrastructure and support for high-volume messaging workloads. Enterprise security features include encryption for transmitted and stored data as well as SOC 2 Type II compliance. The company also operates an iMessage Agent Store where users can discover AI-powered services that are accessible directly through messaging. Linq is aimed at developers and businesses that want to use messaging as a core interface for AI agents, consumer applications, customer workflows, and other conversational products.
