Stream operates a managed backend platform delivering chat, video, activity feeds, and AI moderation APIs to applications at scale. The stack—Go, PostgreSQL, CockroachDB, Redis, WebRTC, plus Kubernetes adoption—reflects infrastructure built for high-concurrency, low-latency real-time systems. Pain-point data reveals the company is actively fighting scaling challenges, churn risk, and low API adoption, while hiring heavily in engineering (9 open roles) and adding compliance capability—a shift toward enterprise-grade operational maturity.
