Sinch AB (publ), trading on OTCMKTS as CLCMF, is a global provider of cloud-based communications and customer engagement services. The company offers a communication platform as a service (CPaaS) that enables businesses to integrate messaging, voice, video and verification capabilities directly into their applications and workflows. Sinch’s product suite includes SMS and MMS messaging, voice calling, two-factor authentication, number masking and mobile marketing tools, all delivered through scalable APIs and web interfaces.
Founded in its current form following the rebranding of CLX Communications in mid-2019, Sinch traces its roots to earlier Swedish telecom operations established in the late 2000s. The company has grown both organically and through strategic acquisitions, expanding its service portfolio and customer base across multiple verticals such as e-commerce, financial services, gaming and on-demand platforms. Sinch completed its initial public offering on Nasdaq Stockholm in June 2019 and has since strengthened its global footprint by integrating complementary businesses to enhance its messaging, voice and verification capabilities.
Headquartered in Stockholm, Sweden, Sinch operates data centers and maintains regional offices in North America, Europe, Asia-Pacific and Latin America. Its geographically distributed infrastructure ensures reliability and low latency for international messaging traffic. Sinch serves a wide range of enterprise and mid-market clients, supporting high-volume transactional alerts, promotional campaigns and real-time conversational services. Under the leadership of CEO Oscar Werner, the company continues to invest in network expansion, real-time analytics and AI-driven engagement tools to meet evolving customer communication needs.
