About

One of the top 3 global CPaaS providers by message volume, with a differentiated owned carrier network and broad omnichannel messaging portfolio

Sinch is a leading cloud communications platform-as-a-service (CPaaS) provider headquartered in Stockholm, Sweden. The company offers a comprehensive suite of communication APIs and tools that enable businesses to integrate SMS, voice, video, email, and rich messaging (RCS, WhatsApp, Viber) into their applications and customer engagement workflows. With a global carrier network spanning over 190 countries and direct connections to more than 600 mobile operators, Sinch provides the infrastructure backbone for high-volume, mission-critical communications at scale. Founded in 2008 and publicly listed on Nasdaq Stockholm, Sinch has grown aggressively through organic development and a series of strategic acquisitions — including Mailgun, Mailjet, MessageMedia, Pathwire, and CLX Communications — transforming itself into one of the world's largest CPaaS providers. Its platform serves over 150,000 businesses globally, ranging from SMBs to large enterprises, across industries including e-commerce, financial services, healthcare, and retail. The company processes billions of messages and calls annually, making it a critical enabler of customer engagement and marketing automation. In the AdTech and MarTech ecosystem, Sinch plays a significant role by powering omnichannel customer communications for brands, agencies, and platforms. Its messaging infrastructure supports use cases such as promotional SMS campaigns, transactional notifications, two-factor authentication, conversational marketing, and customer support automation. Sinch competes directly with Twilio, Vonage (Ericsson), and Bandwidth, and positions itself as a differentiated provider through its owned carrier network, global reach, and integrated email-plus-messaging capabilities.
