What Linq is
Linq is a communications platform and API for businesses and developers that need to send and receive messages or make calls. Its messaging API supports iMessage, RCS, and SMS, selecting a protocol automatically and falling back when needed. Rich messaging includes media, group chats, reactions, effects, typing indicators, polls, and real-time webhooks. Linq names customer support, sales engagement, appointment reminders, order notifications, and AI agents among its use cases. Developers can use API documentation and CLI access; Linq says a first workflow can be built in less than five minutes. It advertises 99.95% uptime and latency below 120 ms. Linq 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 is free and supports up to 20 contacts. Pro is $260 a month; Enterprise pricing is custom. Platforms include Android, iOS, web, and API.
