Sinch has been named a Marketplace Partner in the SpaceX Super Intelligence (SpaceXSI) Partner Network, the company announced on November 4.
The partnership brings Sinch’s voice, verification, messaging, and email infrastructure into applications built with Grok Build (formerly Cursor).
SpaceXSI is focused on frontier AI, intelligent agents and agentic software development. As developers create more advanced applications in Grok Build, the company says they increasingly expect core services to be available directly inside their workflows rather than added later.
Through the partnership, Sinch is integrating its communications tools into Grok Build so developers can build applications that let AI agents handle customer inquiries, automate routine interactions and support other business processes. The company says the integration is designed to give those applications the reliability, scale and compliance controls that enterprises require.
“Grok Build is massively expanding what developers can develop and Sinch makes sure what they build can reach customers in production,” said Petter Bengtsson, SVP, AI Ecosystem & Partnerships at Sinch. “Through the SpaceXSI Partner Network, Sinch is closing the gap between working code and production-ready customer communications. Developers build with AI and connect with customers on infrastructure designed for reliability, scale and complex compliance requirements.”
Sinch says embedding communications capabilities into AI-powered development workflows allows developers to build and test them during the application development process instead of integrating them afterward. The integration runs on Sinch’s existing carrier-grade infrastructure, which the company says is already used at enterprise scale and can support applications as they grow from initial users to millions.
The Sinch plugin is available now in the Cursor Marketplace. It includes the Sinch Model Context Protocol (MCP) server and 15 Skills in a single installation, giving developers and AI coding agents access to current Sinch API knowledge and tools.
According to the company, the plugin is meant to speed up common tasks such as integrating messaging and verification workflows or testing communications features, reducing the need to search documentation or build integrations from scratch.
