Sinch Tech Stack

Global communications platform processing 900M+ customer interactions annually

IT Services and IT Consulting Stockholm, Stockholm County 1,001–5,000 employees Public Company

Sinch operates a multi-channel customer communications platform (SMS, email, voice, RCS) handling 900+ million interactions yearly for 190,000+ customers. The tech stack reveals a dual-layer architecture: Salesforce ecosystem (CPQ, Billing, Revenue Cloud, Marketing Cloud) for go-to-market and enterprise customer operations, paired with cloud-native infrastructure (Kubernetes, PostgreSQL, Java, Node.js) for the messaging backbone. Active adoption of GCP, LangChain, and code-generation tooling signals a pivot toward API-first developer experience and AI-powered messaging features, while the engineering-forward hiring velocity (67 engineers vs. 53 sales roles) and SDK/infrastructure projects suggest deepening platform capabilities over sales expansion.
