Sendbird, founded in 2013, built its original business as chat and messaging infrastructure, APIs and SDKs letting any company add real-time chat features to their own app, marketplaces, dating apps, gaming communities, well before AI customer support existed as a category, with customer support being one use case among several for that underlying messaging layer.
AI agent capabilities have since been added on top of that established messaging infrastructure, giving Sendbird a different starting point than purpose-built support platforms: a proven, high-scale messaging backbone originally built for a much wider range of applications than support alone, now extended with automated resolution features.
A free tier covers limited use, with paid plans priced separately for AI features on top of core messaging infrastructure. For a company that wants AI support agents built on genuinely proven, high-scale messaging infrastructure rather than a support-specific platform built from a narrower starting point, Sendbird's broader messaging heritage is a specific point of technical credibility.
