What Linq is

Linq is a communications platform and API for businesses and developers to send and receive messages or make calls across iMessage, RCS, SMS, and voice. Its messaging API supports iMessage, RCS, and SMS, with automatic protocol selection and fallback. Rich messaging features include media, group chats, reactions, message effects, typing indicators, polls, and real-time webhooks. Linq identifies customer support, sales engagement, appointment reminders, order notifications, and AI agents as use cases. Developers have API documentation and CLI access; Linq says a first workflow can be built in less than five minutes. The company advertises 99.95% uptime and latency below 120 ms. It says it holds SOC 2 Type I and Type II certifications, encrypts sensitive customer data stores at rest, and restricts privileged access to encryption keys. The free Hobby plan costs nothing for up to 20 contacts. Pro costs $260 a month and includes zero data retention. Enterprise pricing is custom.
