Sinch positions itself as core communications infrastructure, a CPaaS routing SMS, voice, email, and identity verification through a single set of APIs, and is now extending that plumbing toward agent and AI use cases, including calling its APIs directly from inside code editors. Public conversation about the company leans heavily on amplification of its own published research on the gap between enterprise leaders' confidence in AI readiness and the rollback rates their teams actually see, alongside conference appearances and quarterly product-showcase coverage. Day-to-day integration commentary is a smaller share of the picture so far.

Business Profile
Sinch was founded in 2008 in Stockholm as an SMS aggregator and has grown through a mix of acquisitions and organic expansion into a public communications infrastructure company on Nasdaq Stockholm, with roughly 4,000 employees. Its acquisition of Mailgun and Mailjet added transactional email delivery alongside its messaging, voice, and verification APIs, rounding out a Customer Communications Cloud spanning SMS, RCS, WhatsApp, voice, and email. The company reported $2.8B in FY25 revenue, down 6% year over year, with a market cap near $2.9B, and continues to position itself around AI-era communications infrastructure for enterprise developers and operators alike.
Agent Readiness
Measures how easily your agents can build on it — API, MCP, CLI, SDK, docs depth. Methodology →
Sinch has shipped a full stack for agent access to its communications APIs, including a documented API, an MCP server, and SDKs, and demonstrated that stack concretely with a plugin that lets Cursor call its messaging APIs directly from inside a code editor. Its quarterly product-showcase cadence has begun explicitly framing new releases around AI, positioning the API layer as infrastructure agents can call directly rather than only a UI built for people.
