Linq

Linq operates as a B2B software and infrastructure provider. It supplies APIs, testing tools and deployment tooling that let businesses embed messaging and voice capabilities into their own applications. Value is created by reducing integration complexity, supporting high-volume and low-latency delivery, and enabling newer channels such as native iMessage alongside more standard SMS, RCS and voice. Revenue is generated when customers move from testing into live production usage and expand throughput or enterprise support needs.

Linq is a private US software company that provides communications APIs and developer tooling for businesses building messaging-based applications and workflows. Its platform gives programmatic access to iMessage, RCS, SMS and voice, with supporting products such as a sandbox testing environment and CLI tooling to speed integration and deployment. The company is positioned as a developer-first infrastructure provider rather than a consumer messaging app.

The business model is based on selling API-driven messaging infrastructure to developers, product teams and enterprise buyers that need dependable, scalable customer communications or conversational AI workflows. Linq makes money through a mix of software access and usage-based messaging economics, with free or low-friction onboarding via sandbox tools and monetisation tied to production deployment, message volume and enterprise requirements.
